OMG, even the producers of Eastenders couldn’t produce an end of year ‘cliff hanger’ this good. Just when we thought you might have cracked it along came the ‘doof-doofus’ (Rob’s closure piece). More excited for part 2 than I am for anything on Christmas TV this year! Superb chaps!!!
Rob are you and Chris available for Weddings, Funerals and Bar mitzvah’s in the New Year 😂, your both look proper perfect in Chauffeurs caps , Happy New Year 👍🏻.
I think Chris is going about it in exactly the right way, but I am sure the ECU is protected against polarity mistakes, I have learnt that it is best to do as many simple checks as possible and not to assume the most complex part of the problem is causing the fault. with a car that did work until it spent a long time unused it is very unlikely the ecu is the fault. Check the pumps are running, check the fuel pressure sensor, check the temperature sensor, a corroded connection could be seen as a high resistance which may make the temp guage go to hot, unplug it and see what happens, check the ecu earths etc etc, I am probably repeating what you already know, but it bears repeating! Every time I assume a fault is a difficult one it turns out to be somethiung simple! Phil
Unfortunately it wasn't ECU was burnt out most likely someone put way to much power in it I do know tho cars do have a battery charger which you can plug in if the car isn't used that much to stop the battery from going flat.
Wrong, forward a few episodes It was the ECU that was at fault, burned out due to as Chris states some numpty connecting the battery leads the wrong way round ☹️☹️☹️
The Mike Ed friction was just for the TV, however, little did we know Brewer was a bit of a plonker off screen, ultimately Ed is a gentleman through and through…!!
Often ECU's are designed to have a single high current protection diode on the pcb to product the input from reverse polarity, often this will blow but in doing so it protects the rest of the board. There will possibly be other components on the input side too to protect against load dumping which could have failed due to a surge. Might be worth having someone familiar with pcb level work to locate and check the integrity of the diode etc. BBA-Reman might also be able to help with this.
If it is possible to examine the ECU PCB, it would be worth noting, that there could be several SMD Fuses on the PCB which are present to protect the 'delicate' components - such as the ICs and Main Microprocessor. These SMD Fuses will have an "F" designation, and can be checked with a DMM. I have repaired many electrical items with Microprocessors, just by doing this, replacing the blown SMD Fuses on the PCB. I hope that this helps.
Reverse polarity protection doesn’t burn down because its usually designed to do job without any drama. What can burn down albeit very rarely is usually TVS diode which is there to protect circuitry from over voltage. However they are also designed to sustain quite a bit of hammering and will usually burn your fuse way early before throwing the towel themselves. Usual failure sources for ecu which has some age are capacitors (electrolytic or tantalum) which can fail due age or temperature and short-circuit, resulting cascading failures of all kind of components down and upstream. In which case new ecu is more economical option.
yes and if preceded by a fuse or self resetting fuse it could protect the ecu or leave it open for a simple repair. I bought a hardly used whirlpool expensive dryer off ebay for 50 quid and lo and behold there was a wrong value fuse under the top which I replaced with a higher value one, it's still working 10 years later...I wouldnt be too disheartend at that point..
Just a possible hint - as know from dealership experience of messing up battery swaps that there is a battery management ecu hidden behind the left hand (starter battery) that can get fried if you attempt to jump start direct to terminals or as in this case wire up wrongly - probably not the problem but just an idea of something else to eliminate. Also you will be aware post battery changes that you have to drive the car for a few miles so it can reset all the various computers e.g. steering, suspensions, windows, etc etc - There is a very specific procedure on what to do pre removal on steering position, brakes, etc etc. I heard the dealer saying something like over 100 sensors on a continental that gets reset post battery change. Enjoy the journey.
I agree with it having a little ecu for batterys, especially as you said it's bmw parts, after watching salvage rebuilds for a while I decided to clean up a few cars, I have just got a BMW from that year and noticed the battery has its own little circuit board, But what I would want to suggest is, could the temp wiring be shorted so when power on its getting full 12v therfore the temp skyrocket and also causing electrical issues so you can't read the ecu?
Polite observations! If this Bentley has been sitting for some time, and it has, and the fuel gauge is showing almost empty, put in a full tank of fresh petrol. One gallon of fresh gas isn’t going to cut it! Next, put in a set of fresh spark plugs. Are the existing ones actually sparking? Is there coolant in the radiator? Fresh coolant would be nice. Oil. What are the current oil levels? Battery. A fresh Varta battery I am sure would make a WORLD of difference! Good luck!
I've had a bit of experience with arnages. I once had one intermittently overheat and the car would go in to limp mode and then turn off and cut ignition until it cooled. If yours thinks it's overheating pegging the gauge immediately it will not let it turn over or start.
I have no knowledge of these cars ,but I agree the ECU is seeing the temp gauge in the red and the safety has kicked in and disabled it. I also had a thought the ECU has a fuse ,if that's blown there will be no communication.. Actually second thoughts ..The scan tool is communicating so maybe I'm wrong with the ECU fuse
when the ignition is switched the ECU sends a temp signal to the cluster. if there is no input it will max out. this is how it's done on all makes with a bosch ecu. the ecu is just not communicating at all
Some of my fave bits when Chris goes through his thought process to address an issue, most you just see on the tools but hearing the process of deduction and possible issues is awesome and helps peeps learn. GUYS YOU ROCK
I think you've got an Arnage T there, which is the high output variant (450bhp). It certainly has Arnage T alloys. Lovely car and have always wanted one. You may find it is a VW ECU, as I'm pretty sure they had purchased Bentley by then. The key looks like a VW-style key, rather than BMW. The motor is very simple and originates from the 1960-1970s Rolls Royce 6.75 V8 unit. I am almost certain it is pushrod rather than overhead cam. If anyone can fix it, you guys can!
Bit of a back story on VW and BMW. BMW thought they were buying Bentley with Rolls Royce as they were REALLY after Bentley but VW had sussed it was a separate purchase. So BMW didn't get what they were actually after ending up with RR and VW got Bentley.
@@1chish other way round. VW were buying RR & Bentley. But BMW sneaked in and bought the RR car rights from Rolls Royce aero engines (as the car company didn’t own the rights to the name). BMW were co developing an aero engine with Rolls Royce at the time. VW paid a lot of money thinking they were getting Rolls Royce, but just got the factory and Bentley.
It's a 6.75 litre V8, which was the standard motor used in Bentleys and Rollers in the 60s/70s/80s. The one you've got is a turbo charged Arnage T, which is quite a rocket ship. Enjoy it, once you get it running.
Rob, Chris - Thanks for posting and good luck with the car - If you are interested in the BMW-VAG connection it goes as follows, Rolls Royce cars (which also made Bentleys) was owned by Vickers. They sold it in the 90s and there was a battle between BMW and VAG - VAG won the actual company and factory, but BMW were able to separately buy the rights to the Rolls Royce name for cars (Rolls Royce aero engines always owned the Rolls Royce name and historically allowed the car company to use the name under licence). Prior to the sale, Rolls Royce used some BMW parts like engines. After the sale, VAG had the factory but could only use the Bentley name. VAG then started to get rid of all the BMW parts (including engines) in the Bentley cars. Bentley under VAG went back to the old 6.75 litre V8 engine that you have in your car. BMW built a complete new factory to make Rolls Royces, starting from scratch and using BMW parts. That's why your car has VAG ECUs (although it might still have a few BMW parts that they hadn't got around to replacing). As others have said, the engine design is very old and pretty reliable, but of course it now has loads of electronics attached for performance, emissions etc. Good luck - hope you get it to run.
Rob, you get all excited about a fiesta starting for the first time. I hope you’re sitting down when this one finally fires up! Good luck with it guy I really hope you get a result here..🤞
And this is why I hate computers on car's I am an old school retired mechanical engineer the more electronics you put in a car the bigger the headaches become .Happy new year lad's.
Just some tips.. sometimes it is as simple as checking that the engine ECU power supply is ok, there is typically a dedicated fuse(s) for the engine side electrics, sensors, etc. Could also just send off the engine ECU to ECU specialist to verify it functions well, before attempting to source another which will need recoding, etc..it may come up to have no issues at all.
I can listen to rob and chris talk about cars all day, they explain things in simple terms for people like me lol ..hope you get that beauty up and running and make a nice profit lads 😀
Well, I never expected to see a Bentley on the channel, but I'm really glad you have one. I know most of us will never have the opportunity to own one, but it's a great example of even expensive high end cars can have mysterious faults too. I sincerely hope it stays on the channel, as it's going to be interesting to see of you can get it running.
Just to let you know guys this is the 5pm video we thought the time wouldn’t matter today. A lot of the running gear around this car is bmw including all the breaks cooling systems etc however after a bit of searching online with the part number the ecu is vag and fitted to some Audi’s 👍
Well they fitted different engines depending on the colour of the Bentley badge. Red or green. Either bmw or the old chuffer reliable Bentley engine with twin turbos added. Maybe this is the later version, with facelift headlights
This is a really good one! If anyone is going to persevere and get to the bottom of the problem it’s you guys. It’s amazing what small issues do bring modern cars to a halt and are actually easily fixed. Can’t wait to see part two!
Merry Christmas guys, thought it was comical with Rob sitting in the car and beeping "Chris come over here" the Bentley mindset has already kicked in. The battery terminal damage suggests exactly what you thought, reverse polarity jump start attempt.
Really hope you can sort this one boys , very impressive car ! I love that your oit of your comfort zone , albeit you can give it back ! The fact your good enough to know when to walk away when its too risky , shows discipline and good business sense ! I tip my hat to you both , love the content keep it coming 👍
That’s a cracking car guys. The team at Classics Monthly have been running an earlier Bentley and have established contacts with several specialists. They are based at Cudham in Kent. Long shot but they might be able to offer some help. 👍
You can have the ECU tested for about £50 and they can rebuild, reload the data, etc. Might even be a swap out, if there's one available. Send it away, wait about week and get it back tested, fully working.
Rob, Chris you’ve made my day, I really wasn’t expecting to see a video from ye this week. Thought you’d both be enjoying a much deserved break - I just know you’ll get that Bentley started and back on the road. Seasons greetings to you both!
I live 2 mins away from Bentley in Crewe, used to work there on the maintenance and saw these getting built everyday. Keep at it guys you will crack it.
Hope you had a fantastic Christmas guys. I absolutely love the Arnage (it's a V8 by the way). I thoroughly enjoyed this video and the investigation work. Chris is a top mechanic. I'm sure you'll get it started and I'm looking forward to it!
Absolutely love your videos. Rob and Chris are like a married couple without the rows! Chris is so laid back he’s almost comatose. 😀 Please keep the videos coming, nice to see this Bentley, something a bit different to look at.
Looking forward to the next instalment. There are few things more satisfying than getting an electrical fault sorted where somebody else has given up. If it was a reverse polarity fault let's hope it hasn't fried any other modules. Good luck!
Nice video proving what I have always said that Bentleys are such a great car for the home enthusiast who, with a few tools and little specialist knowledge, can make all necessary repairs! Hope you will sort this out and make a fortune because it always favours the brave! I have wanted a Continental for years but the head always overrides the heart and I never will!
The engine is the old RR/Bentley 6.75 litre V8, originally made in the fifties. updated and turbocharged. It was always a great engine and is still in production for the Arnage.
We love the challenging Investigation cars Rob especially when Chris takes the time to explain the thought process you go through to solve them. Lovely car, lets hope for SRUK profits rising in 2022. Cheers, Mac in Stafford.
What a beauty! Beautiful content and video. I like how you are not afraid to look at different cars. Very different from your regular videos and had me glued as usual. Would love to see running again along with you guys turning a profit.
Wow what a gorgeous car..! I hope you continue to work on it and get it running and driving, I know that you and Chris are not easily beaten..!! Can’t wait for the next video on this , keep it up guys 🙏🏻😃❤️
All the best to you and families Rob, Chris, all the subscribers and supporters of the channel. Its been amazing watching you grow and I love the community around this channel - a real family of enthusiasts 💯
I have been watching for a long while now. Since Chris wouldn't have a bar of the camera. It's amazing and fantastic to see Chris come out of his shell and get in front of that camera
Great video fellas! i'm wondering if the coolant temp sensor has failed, and showing as overheating, then maybe the ecu wont let it start to protect the engine?
Well I never expected a Bentley on the channel! A real Christmas bonus for us. Hope you both manage to get it going, would love to see you both taking out on it's first drive. The potential profit is a great carrot for you both and great content for us.
It's gonna be a challenge, but what an awesome ride! Had to laugh for a Second at you two trying to push that three-ton beast. Hope y'all didn't strain anything important!
Oh the joys of modern, sophisticated cars and all their electronics. I always enjoy your work on ordinary family cars, but this is a special way to end the year with an exclusive car, throwing you a challenging riddle to solve. So far "only" your time has been invested. Fingers crossed you will be able to pinpoint the problem before investing in expensive spare parts, that then turn out not to fix it.
My XJR hated being low on fuel. Always ran happier with at least half a tank of fuel. What i mean is a empty fuel tank can produce condensation which can end up in the fuel system. Some of these cars will not start with a door open. Do you have to cover the brake for it to start ? . Anyway hope you get it going soon and i cant wait to hear that stunning piece of engineering running. Great car.
Mega thumbs up on this video. Ever since I started watching your channel I've been hoping for an old Rolls or Bentley to be one of the cars you work onl, so like the saying goes, everything comes to those who wait!
Crack the ECU open and check any diodes, there’s usually reverse polarity protection diodes. If there’s any reading short circuit take them off and test them removed. If you do find any that are short circuit then cheap to replace - you can also run the ECU without them as a test if it’s across the supply and ground.
It might be worth trying Ghost Motors in Borough Green (Rolls Royce and Bentley specialists) to see if they can offer any help or advice. Good luck guys!
Rob, Chris, you’ve pulled a rabbit out the hat with this one. What a car, and what a challenge for you both. I must admit I never expected you to be dealing the cars of this type. What a treat for Christmas. Cheers guys, I’m eagerly awaiting the next instalment. All the best….
Brilliant. I mentioned a few uploads back that I wasn't thrilled with another Citroën van and the boys have blown the roof off this time with a Bentley Arnage. I loved these cars and the coupe version was a thing of sheer beauty. Great content.
Could it be as simple as the temp sensor(s) ? just a thought as that would be my train of thought seeing the gauge. Thanks guys for such great content and all the very best to you and yours.
Chaps this is a classy motor, I know you will get that beaut running. And Rob don t beat yourself up ref not spotting the temp guage straight away you found it while fault finding and now are well on the road to fixing it. Can't wait to see this finished and most of all you getting a decent profit.
Arnages are my favorite body style of the Bentleys; seriously a nice, clean ride. I can't modify my truck until it's 25 due to emissions we have here in Texas in some counties, but always thought it would be fun to have one of these V12s in it as it's not a great deal a larger motor than the 6L already in it, and the weight is also about the same between these HEAVY cars and a full size Silverado. Hope y'all can make some progress on it and continue with the project, that would be plumb neat.
Nice car gents. Would it be as simple as an interlock in the ECU not allowing the engine to start if it has a coolant temperature reading that is off the scale i.e. to stop any further engine damage??
@@mwh2412 good point but possibly Not if it was stored in the ECU as the master control as that was not responding on the CAN bus, the analog style metering may be different from the sensor. I'd start with the engine ECU and fuel lines and tank to make sure water hadnt condensed into the fuel system (from the cold tank walls) and then the spark plugs and spark,
You never know what the next video is going to cover on this channel. Very nice find, didn't know these held their value that much. Usually the more expensive or exotic the car, the more it depreciates. Hope you & Chris have a good new years.
20K miles and the car fails you !!!??? For THAT kind of money you'd expect a car to go for life. Seems like the more expensive the more they break down nowadays.
I think it was allowed to go flat whilst stored in a barn. Somebody attempted to start it with a jump pack and got the polarity wrong. It’s blown the ECU and possibly more. What an expensive and destructive mistake. Hope that the parts are identical to a BMW 7 series of the same vintage.
What a beast of a car. I work on a Daimler Ferret Scout Car here in Australia. I've also worked on Land Rovers and Jags. British cars sure can be complicated. This is a great video. Very interesting. Too many electronics in modern vehicles. Looks like the ECU was the easiest thing to get to.
A long time friend of mine told me a few months back that his brother did the same thing, put jump leads wrong way around. It was a different car, Mercedes , but it did a fair bit of cooking! Can't say I know in depth about this car but I think you are on the right track Gents. This could be a 'nice little earner ' and let's hope it is. Thanks Rob and Chris for the early video, we don't mind today.😁👍
I remember a customer had one of those bentleys back in the day -probably 2001 2002. it had an issue of some description and he plugged the car in to some sort of modem and Bentley could check the car remotely, I was amazed at the time that was possible
what a cliffhanger 👀 great video as always 👏

Loved it when Chris said the 'Fuels low, so I put a gallon in it' ... that's probably just about enough to fill the fuel lines!!
Or make them wet!
sounded like it broke his heart to spend that much as well
what about a squirt of quick start up the air intake
and then consumed with one blip of the throttle.
I'm not that mechanically knowledgeable but I could listen to Chris explain things all day long I actually learn so much from the two of you 👍

This is a really good one! If anyone is going to persevere and get to the bottom of the problem it’s you guys. It’s amazing what small issues do bring modern cars to a halt and are actually easily fixed. Can’t wait to see part two!
Merry Christmas guys, thought it was comical with Rob sitting in the car and beeping "Chris come over here" the Bentley mindset has already kicked in. The battery terminal damage suggests exactly what you thought, reverse polarity jump start attempt.
I spotted that too, all Rob had to say was "can you come over here my good man" :-)
@@dontuno it cracked me up, but I would probably be worse....
Really hope you can sort this one boys , very impressive car !
I love that your oit of your comfort zone , albeit you can give it back !
The fact your good enough to know when to walk away when its too risky , shows discipline and good business sense !
I tip my hat to you both , love the content keep it coming 👍
A serious car for serious money,good looking tank,luxury at its finest 👍
That’s a cracking car guys. The team at Classics Monthly have been running an earlier Bentley and have established contacts with several specialists. They are based at Cudham in Kent. Long shot but they might be able to offer some help. 👍
You can have the ECU tested for about £50 and they can rebuild, reload the data, etc. Might even be a swap out, if there's one available.
Send it away, wait about week and get it back tested, fully working.
Watching Chris run few permutations in his head is great. All us car fidlers do the sane but he is a master
Haven’t clicked on a link so quick since the Sierra Cosworth!!!!
I 2nd that
Same
@luckyadam331 something's are just that important
Before changing ecu, definitely worth sorting the temp sensor first as that could be the problem. Look forward to part 2 gents 👍
Rob, Chris you’ve made my day, I really wasn’t expecting to see a video from ye this week. Thought you’d both be enjoying a much deserved break - I just know you’ll get that Bentley started and back on the road. Seasons greetings to you both!
I live 2 mins away from Bentley in Crewe, used to work there on the maintenance and saw these getting built everyday.
Keep at it guys you will crack it.
I love the way Chris is just having a lay down while you have a big old chat. 🤣
Never mind anything else with this car, I'd just like to say well done for physically pushing it into the workshop👍
Hope you had a fantastic Christmas guys. I absolutely love the Arnage (it's a V8 by the way). I thoroughly enjoyed this video and the investigation work. Chris is a top mechanic. I'm sure you'll get it started and I'm looking forward to it!
Absolutely love your videos. Rob and Chris are like a married couple without the rows! Chris is so laid back he’s almost comatose. 😀
Please keep the videos coming, nice to see this Bentley, something a bit different to look at.
Had to laugh when you said 'let's push it in' I was thinking no way! Haha but you and Chris must have had your weatabix
It was like something from Only Fools and Horses or even Minder!
I like these guys, no bullsxxt. Straight, unedited planning and debates.
The range of motors you guys do is quality! Chris will keep this Bentley for himself!!! Good work 👏🏼
Looking forward to the next instalment. There are few things more satisfying than getting an electrical fault sorted where somebody else has given up. If it was a reverse polarity fault let's hope it hasn't fried any other modules. Good luck!
Keep at it chaps, I've got a good feeling about this.
Nice video proving what I have always said that Bentleys are such a great car for the home enthusiast who, with a few tools and little specialist knowledge, can make all necessary repairs! Hope you will sort this out and make a fortune because it always favours the brave! I have wanted a Continental for years but the head always overrides the heart and I never will!
Hope you had a good Christmas Rob and Chris and have a great 2022.
The engine is the old RR/Bentley 6.75 litre V8, originally made in the fifties. updated and turbocharged. It was always a great engine and is still in production for the Arnage.
We love the challenging Investigation cars Rob especially when Chris takes the time to explain the thought process you go through to solve them. Lovely car, lets hope for SRUK profits rising in 2022. Cheers, Mac in Stafford.
Can already hear Rob can’t wait to start cleaning it, be a few episodes in that alone it’s like a cruise ship
Never thought we'd see a Bentley!! Interesting to see how it pans out.
Why? They started the channel with a Ferrari lol
What a beauty! Beautiful content and video. I like how you are not afraid to look at different cars. Very different from your regular videos and had me glued as usual. Would love to see running again along with you guys turning a profit.
Wow what a gorgeous car..! I hope you continue to work on it and get it running and driving, I know that you and Chris are not easily beaten..!! Can’t wait for the next video on this , keep it up guys 🙏🏻😃❤️
All the best to you and families Rob, Chris, all the subscribers and supporters of the channel. Its been amazing watching you grow and I love the community around this channel - a real family of enthusiasts 💯
I have been watching for a long while now. Since Chris wouldn't have a bar of the camera. It's amazing and fantastic to see Chris come out of his shell and get in front of that camera
That will be impressive when you get it running and go out in it to collect the coffees! It will probably cost £5 in fuel just for that round trip.
Best video yet Rob looking forward to part 2, the apprehension in your face and voice at the beginnig to the confidence at the end is a joy to see. 👍👍
Great video fellas! i'm wondering if the coolant temp sensor has failed, and showing as overheating, then maybe the ecu wont let it start to protect the engine?
That’s what I thought the moment I saw that gauge, not that I know anything about Bentleys but I reckon it could be something like that.
I second that, it's certainly logical but sods law probably not that simple!
I always enjoy Chris fault finding, he's the man when it comes to auto electrics. I'm looking forward to part two. All the best guys.
Lovely Bentley. Do they do a ladder rack for it? Love to have it for my window cleaning round. Always wanted to go upmarket.😃
The guy that cleans windows round my way has a hearse...😂😂😂
Well I never expected a Bentley on the channel! A real Christmas bonus for us.
Hope you both manage to get it going, would love to see you both taking out on it's first drive.
The potential profit is a great carrot for you both and great content for us.
All the best with this one Rob & Chris! Really hope you get it going!
From Fiat's to Bentleys you guys do it all! Top video lads. I hope you both had a Merry Christmas
It's gonna be a challenge, but what an awesome ride! Had to laugh for a Second at you two trying to push that three-ton beast. Hope y'all didn't strain anything important!
You can’t leave it there, I’m gripped! You two always come up smelling of roses, this is going to be fantastic, what a car.
I can't wait to see how this pans out.
Oh the joys of modern, sophisticated cars and all their electronics. I always enjoy your work on ordinary family cars, but this is a special way to end the year with an exclusive car, throwing you a challenging riddle to solve.
So far "only" your time has been invested. Fingers crossed you will be able to pinpoint the problem before investing in expensive spare parts, that then turn out not to fix it.
Hope you had a good Christmas Rob and Chris 👍🏼
My XJR hated being low on fuel. Always ran happier with at least half a tank of fuel. What i mean is a empty fuel tank can produce condensation which can end up in the fuel system. Some of these cars will not start with a door open. Do you have to cover the brake for it to start ? . Anyway hope you get it going soon and i cant wait to hear that stunning piece of engineering running. Great car.
Fingers crossed Rob and Chris hopefully it’s the ecu and you get the Bentley running good look 👊👊👍
Mega thumbs up on this video. Ever since I started watching your channel I've been hoping for an old Rolls or Bentley to be one of the cars you work onl, so like the saying goes, everything comes to those who wait!
" Check the oil, check the tyres ! " Yes well car vertical is certainly on the ball ! 😅😃😂😁😅😃😂😁😅😃😂😅
It's sound advice to be fair, most private buyers who've bought from me don't even open the bonnet!
Crack the ECU open and check any diodes, there’s usually reverse polarity protection diodes. If there’s any reading short circuit take them off and test them removed. If you do find any that are short circuit then cheap to replace - you can also run the ECU without them as a test if it’s across the supply and ground.
Could the ECU be cutting the spark and fuel because it thinks the engine temp is in the red? Good luck with this one, what a car!
That’s what I thought check the sender unit to see if it’s bad. Maybe disconnect it and try cranking the engine?
Could be but the list of "ECU not communicating" codes is a bit suspicious I'd say.
Absolutely love the way you guys go through the problem solving side of your job, can't wait for next update on this👍👍
It might be worth trying Ghost Motors in Borough Green (Rolls Royce and Bentley specialists) to see if they can offer any help or advice. Good luck guys!
Rob, Chris, you’ve pulled a rabbit out the hat with this one. What a car, and what a challenge for you both. I must admit I never expected you to be dealing the cars of this type. What a treat for Christmas.
Cheers guys, I’m eagerly awaiting the next instalment.
All the best….
A Bentley of this age can't be a gamble for you guys looking forward to seeing the end of this project and the results
Brilliant. I mentioned a few uploads back that I wasn't thrilled with another Citroën van and the boys have blown the roof off this time with a Bentley Arnage. I loved these cars and the coupe version was a thing of sheer beauty. Great content.
Could it be as simple as the temp sensor(s) ? just a thought as that would be my train of thought seeing the gauge. Thanks guys for such great content and all the very best to you and yours.
Chaps this is a classy motor, I know you will get that beaut running. And Rob don t beat yourself up ref not spotting the temp guage straight away you found it while fault finding and now are well on the road to fixing it. Can't wait to see this finished and most of all you getting a decent profit.
Rob will get a “brand new second hand battery” on her and she’ll fire straight up 😂
Chris is a trouble shooting car wizard, a very methodical guy that understands how things work... What a team you two are.... Cracking channel✌️
Wish you both a Happy New Year.watching you both has made my year in lock down go fast thanks
Arnages are my favorite body style of the Bentleys; seriously a nice, clean ride. I can't modify my truck until it's 25 due to emissions we have here in Texas in some counties, but always thought it would be fun to have one of these V12s in it as it's not a great deal a larger motor than the 6L already in it, and the weight is also about the same between these HEAVY cars and a full size Silverado. Hope y'all can make some progress on it and continue with the project, that would be plumb neat.
Nice car gents. Would it be as simple as an interlock in the ECU not allowing the engine to start if it has a coolant temperature reading that is off the scale i.e. to stop any further engine damage??
They’d be able to read a fault code on it if it was that.
@@mwh2412 good point but possibly Not if it was stored in the ECU as the master control as that was not responding on the CAN bus, the analog style metering may be different from the sensor. I'd start with the engine ECU and fuel lines and tank to make sure water hadnt condensed into the fuel system (from the cold tank walls) and then the spark plugs and spark,
Loving this channel. A better format and more realistic than the wheel dealers. Big fan. Love it very much.
What a corker of a video as a Christmas special. Hope you have a good drive
You never know what the next video is going to cover on this channel. Very nice find, didn't know these held their value that much. Usually the more expensive or exotic the car, the more it depreciates. Hope you & Chris have a good new years.
How much was it when new though?
This is going to be good and I can't wait for the second episode. Good luck guys, I've got faith in you.
20K miles and the car fails you !!!??? For THAT kind of money you'd expect a car to go for life.
Seems like the more expensive the more they break down nowadays.
I have the same issue on a 2003 mini cooper.! Just noticed 225,000 Subscribers now! Well deserved and congratulations.
The immobliser on my car causes the temp gauge to go into the red and goes back to cold position once disarmed. Good luck chaps.
Yes it’s got loads of bits from 750il , best check eBay, could be a cheap deal on it 👍good luck and yes I love the fault diagnosis that Chris done
I think it was allowed to go flat whilst stored in a barn. Somebody attempted to start it with a jump pack and got the polarity wrong. It’s blown the ECU and possibly more. What an expensive and destructive mistake. Hope that the parts are identical to a BMW 7 series of the same vintage.
It turns out to be a Audi ecu 👍
@@sruk Would never have thought that given the vintage. (2004)
What a beast of a car. I work on a Daimler Ferret Scout Car here in Australia. I've also worked on Land Rovers and Jags. British cars sure can be complicated. This is a great video. Very interesting. Too many electronics in modern vehicles. Looks like the ECU was the easiest thing to get to.
Looks gorgeous and only 19k miles….definitely worth the risk on that one….I’m sure u guys can get that running 🤞
A long time friend of mine told me a few months back that his brother did the same thing, put jump leads wrong way around. It was a different car, Mercedes , but it did a fair bit of cooking! Can't say I know in depth about this car but I think you are on the right track Gents. This could be a 'nice little earner ' and let's hope it is. Thanks Rob and Chris for the early video, we don't mind today.😁👍
I can only imagine Robs reaction if they manage to get this wanged over.
I remember a customer had one of those bentleys back in the day -probably 2001 2002. it had an issue of some description and he plugged the car in to some sort of modem and Bentley could check the car remotely, I was amazed at the time that was possible
