"But the N53 is a really good engine"
Cheers Dean, that is exactly what i wanted to hear, some positivity.
The timing of this video is unreal! I'm collecting my 2008 e60 tomorrow. I seen all these receipts in the service history and was wondering why there was so much work done( pumps etc) but I think I'm lucky that almost everything on your list has been done! 👌🏼 cant wait to collect it.
Owen Kenny like wise I’ve just gone to see a 2009 325i trading it after watching the n46 vid.... only thing is I’m a bit sketchy about it... it’s a cat d
cat d is fine mate nothing major if your not planning to sell it then no reason not to buy it for my purposes I wouldnt touch any categorised cars
but if your not in the trade you have no reason to fear
cat d can end up better then a car thats been on the road all its life because being a cat d it may have been off the road for months if not years and it wont have much rust or much mileage which means not much to go wrong
BMW Doctor went to go see the car after... oil was mixed in the coolant and on INPA the cylinders 456 where reading low and 123 was hitting the reds. Was walking away the right decision? (Still stuck with my N43 and he will still do a straight swap) car drives just running really bad.
Great great video mate. Just got my self an E93. Very helpful!!!
Thanks for the video, making a list of things to check before buying an e92 with this engine. It helps know what to ask for of the owner and what to ask of the mechanic to do preventively.
Hi dean, how much would you charge for the software update? im planning on buying an e90 325i with the n53 engine soon, would you recommend the software update as a preventative measure?
The engine update you mention on the last item. I purchased my car a 630lci 2008 with n53 engine. "is there a check that can be done to see if its been done and if not how can I contact you?
@BMW Doctor, do you know if outside of UK it is possible to check with recall were applied to the car? I've been recalled for injectors in 2010, but around same time when HPFP failed, had to pay for it which seems now to be a scam given it was part of recall.
Any details would be more than welcome - thanks!
Hi Doc Dean, thanks for posting all these videos. I've gone through so many in the last few days. I will be contacting you via email in the next couple weeks to get my car updated. I'm UK London based. Bought an 07 N52 2.5l e92 manual with 107k, getting the steering pump and rocker cover gasket and ofhg done for £350 first.. Done the recall a few days ago
No problem mate that’s fine buddy let me know when your ready mate
THANKS ONCE MORE Mister BMW DOCTOR
All issues and campaingns you have mentioned are exact, to complement your video there are two versions N53
272 cv DISA manifold and ECU software N53B30 OL
218 cv without DISA and other software for less power N53B30 UL
Long live living legends NA's 6L.
Congratulations Master
BimmerN53
Which one would you recommend to be reliable? Hope you will answer a 2 year old comment 😅
If I learned anything its that it WASNT A NEW RECALL. nice vid, ty
No mate you got that right it ain’t that’s why don’t believe the USA HOME DIYERS who don’t know anything
Just what as they say from what they have read up that’s all they do and all they know
Hilarious.
@@BMWDoctor hi mate i have a 2008 bmw e60 with n53 im in sydney australia how can you update it i wanted to like you said at the end of the video?
Spot on. Thanks so much for making this vid.
Great video thanks. You’re saying if I go to BMW in 2021 they’ll replace my water pump free of charge?
Did BMW place the modified fuelpump, injectors and waterpump on the late 2012/2013 N53 cars allready? Or do they have the same parts as the first models with this engine?
I’ve recently purchased an N53 engined 630i.
It has a very strong of petrol under the bonnet in and around the manifold.
It there common issue that this might be?
Hi! Very informative video. Thanks!! Is there known problems with the timing chain/guides on this engine? I have a rattle at idle when engine is thoroghly warm(no cold start rattles) also some clattering at warm start when car has stood still 10--15min. When i rev the engine gently there is a metallic ticking that follows the revs. The sound is most prominent if i prod the throttle so revs go up to 2-3k rpm- on the way down theres a clear ticking/rattle. This NOT injector tic.
Help a friend out here, i'm looking to buy a E60 530i, i prefer the LCI if possible
What would you recomend buying? Pre-LCI or the LCI model, regarding n52 vs n53
Sorry for my english 👍🏼
Excellent and informative video, Dean!
thanks home boy
Brilliant video Dean as always mate.
cheers Matthew
I’ve got a question about my parking sensors, I keep taking it to the mechanics but they keep saying there’s a rear module power fault and don’t know how to fix! Any ideas? Help 😢😫
Hi thanks for the video how do I know if the ECU update is needed or not? Bought my e92 with n53 at 111k?
Hey! May I ask what if I have changed 3 injectors to index 11 and the other 3 is old ones with index08, is it makes problem? Btw cold star shaking my engine for few mins.
Hello mate I got 08 plate BMW X6 3L turbo diesel for about £130 exchange high pressure fuel pump and fitted it myself so if ya shop around you can pick them up cheap BMW wanted £1500 plus fitting around the same TOTAL 3k cool vid bro ,,!! From Euro Car Parts i got FUEL pump
Great vid!
Nice one mate. Much appreciated advice
your welcome got your email and replied
I hve 57 plate e90 325i wich curently has rough idle with engine check light but doesnt seem to have lost anypower. My mate done diagnostic with hand held and he said its the secendary o2 sensors? Does tbis sound right before i go ahead and buy new ones or is there any other routes i can go down to find the problem before hand
Hi, is it possible to update my bmw ecu? Believe its on the old one and also if you could diagnose a few faults. I. Getting no eml come on however I have done most of the stuff in the video. New injectors all 6, coils, spark plugs, nox sensor, the oil leak near the fuel filter. Im thinking it may be disa.
Dr Dean, how do I contact you privately in regards to the ECU update? Thanks
Hello Dr Dean, how can I get in touch with you in order to get my N53 updated to the latest version? Thanks for your video
Nice job bro
Hi Dean great info
I was seriously thinking of buying a F10 523i with the n53 3.0 what is your advice car has under 100 k on it realy don't want to take a big risk I'm not over struck on the shape of them but it's a change my heart is with E39 but a real good one is same price has 2010 F10
330i n52 or n53? What do you recommend?
Great video Deano. This was the one I’ve been waiting for from ya. Top man. I’m interest in this ECU update you mention. Also would be good if you could a diagnostici check of the engine. I have a 2009 E64 630i. You may rememeber I contact around Xmas as I live in N. London and wanted to see if we could hook up, so you could see car in person. Let me what’s possible here and if I Can DM you to arrange something. Ta. Marco
Hi mate yeah I remember mate but I don’t go out to people mate most stuff I do is all remotely done mate I can do it all remotely so there is no need for me to move travelling and all that isn’t for me mate
And most people I do I do it remotely
Hey I have 06 330i bmw came with n52 ecu so how came make more power . Is there a sopswear for it?
Can you fit a N54 intake manifold onto a N53 (that doesn’t have the three stage ie 325i)?
Direct Injection requires good quality fuel at all times. US/AUS/NZ have higher sulphur content in our regular 91 and 95 fuels. However, here in NZ we have a high octane 98 fuel that is imported especially for high performance cars and it is for this reason I use it my own E90 330i N52
Hey Kiwi. im looking to buy an 07/08 325/330. would u suggest a N52 rather than a N53 in nz due to the sulfur?
Isn't N52B30 port injected? Asking for a friend...
N52 is port injected bro
Just found a pretty cheap 328i 3.0L Sportpack from 10/2011 (~50k Miles)
What u think about it ?
I drive daily and ~12k Miles a year
Great vid for the N53 Dean, all issues I have done with BMW parts. One of my other pet hates is the damn seat belt arm that passes the seat belt, easy fix though. Keep up the cracking vids. Still the one stop Chanel for BMW info and knowledge 👍
cheers David mate haven't seen you pop up for some time mate im glad you see that others dont at present but they will in the end
@@BMWDoctor yeah been a bit , but I am still as BMW daft. Got a few to vids to catch up on your a bz UA-camr 😀 never cater to the haters, they will never be happy, the content you put out is what keep us loyal subs , haters will always hate
@@davidhenderson7433 lol I wish mate I feel like I haven't posted enough mate lol
We need more ista + videos What’s up with the new version of the icom is it available for sale yet
Finally the N53!👍👍👍 I'm in the UK and would appreciate for a bit of advice on my E91 with this engine as well as probably updating, as you mentioned. How to get in touch with you? Many thanks!
@@BMWDoctor thanks, it is not for a business use, it is a personal matter. Will send you an email shortly with my contact details.
E60 530i Msport LCI N53 . Is this engine reliable? If all the recall has been done and replaced . Looking to buy one.
Hi Doc, thanks for this video, but for me too late😂 Already bought 325i xdrive 2010. This engine is real enigma. Check engine light is constant, first cold start is terible, rough idle, the whole car is shaking, after few kilometres everything is normal, running smoothly. Exhaust is black from smoke, no one knows whats the problem. I changed nox sensor, coils, sparks, the same. It reported missfire on 4th cylinder, change the injector, missfire is now on 5th. Sometimes is cranking very long, it struggles to start. I want to purchase new injectors, but I'm afraid that the problem will not be sloved. If you have some advice, please share. I'm losing hope that I can fix this engine.
I have an n53 engine would you be able to do the update on it remotely ? And how much would it cost ?
Hey man how much would a total update be? I have a slight rough idle when first starting you see and everything updated sounds good. Would it count as a remap for insurance purposes? Would I need to buy stuff for you to do it remotely? Or are you based near London? Cheers mate
Is it worth avoiding an n53 if i can get a car with an n52? 325's in the UK i. think have the n52 up to 2007
Hi Dean, how do i get the update for the n53 engine, thanks Tony
Hy BMW Doctor Dean. I have a small problem on my N53 330i. I have changed The battery Last year. The slow crank persista. What could be The problem? Thank you. Continue The good work!
Does anyone know how this recall for the injectors work? I have phoned bmw UK and they told me theres no recalls on my vehicle , however my injectors are stsrting to fail
i live in Germany and i recently bought an LCI BMW 330i with the N53B30 and i had and rough running problem.
My dealer changed all 6 Injectors sparkplugs and ignition coils - now its better :)
but i want to update my software to the newest one like u said at 11:50.
i recently ordered a obd2 to usb adapter. i will get inpa for my laptop, but how can i update my car?
is this even possible?
Was your misfire only when the car was cold?
Hello doc I was wondering if you can help me I've got a oil leak on my n53 i think it's the sump pan gasket do i need to drop my sub frame to change it or is there a easy way. mutch appreciated
Hi mate how much did you pay to change your injectors
If you was going to buy a 530d or 730d what is the best year to buy cheers bro
Can I asked something, can I mixed different index injector in one bank on N53b30A E92 330i 200ps
Hey Doc, wondering if I can pick your brain for a minute. I started my x3 the other day, didn't drive more than a minute when it shut off... so I pulled over and it wouldn't restart - had the EML light on. So I walked back home with my daughter and discovered all the engine oil on my driveway. Upon inspection 1/2 the oil filter cap had exploded off and all the oil blasted out and made a mess of the left side of the motor (left hand drive - Driver's side - intake side). So I buy a new cap, and new oil... clear the codes - had a over retarded + o2 sensor code. Started it --- Long crank then start - dies... restart - dies... restart.... Runs like crap at about 580rpm. Had a strange rattle sound like someone shaking a spray paint can. So I let it idle - eventually it came up to 800 or so. Eventually I drove it home but anything more than light throttle and it bogs down with a muffled puffing sound. So I'm thinking Oil has contaminated something. I cleaned out the vanos solenoids and cleaned all the connectors. Then it showed code p0341... Cam Position Sensor A bank 1. - should be intake. So I cleaned the connector for that as well as checked the wires.
I notice that oil had spilled onto that electrical connection under the intake manifold, I think it's a 2 wire - whatever that is down there.
Final notes: Starts up after about 4+ seconds of cranking... which isn't normal... usually starts right away. Runs cold about 800+ rpm then climbs up to 1100 after a few seconds - then back to about 500 - 600 once it's up to temp. Beyond that it seems to idle fine. If I rev it, it will bog down like a pufffy intake sound, if I put it in gear it won't move if I apply throttle it will bog.
Any ideas are appreciated. I'm thinking oil is in an electrical connector someplace... Car was running fine before this so I don't see how a sensor could have been damaged from the low oil level.
Thanks!
Nice one Dr Dean 🤛🏼 But is there a way to tell if we've had the update or not!? I searched for ages for a video of changing an N53 rocker but couldn't find one, probably cos of what you said. Anyway pressed on regardless and got it done. Coil packs and plugs while at it. Since then was all gravy until suddenly stopped. Turns over but nothing. Fuel pump? Jumped Chain? Any advice mate very helpful. Are you in London?
Supposed to be going into BMW for 2 recalls in 2 weeks. Battery terminal and blower regulator... But it won't move. You never mentioned the chains in your vid, are they solid?
Hi Dean Im running a 330ci E46 at the moment and was considering changing up to the E92 330i until I saw your vid ###. Is it still a good move over staying with the E46? I do all my own servicing an the E46 without any major drama so not afraid to tackle the mechanics on the E92 but my expertise stops here. Are you UK based in case your services are needed?
Cheers RK
Drive your E46 until its completely done!
Best bmw of that era
I hope you held on to your E46.
Hi I know this vid is a year ago now, but could you please help me update my e92 n53 module? Its done 160k miles now, Ive changed many parts its running fine, but a slight miss fire, it dose need ignition coils and sparks doing them soon, always watch your vids got a lot of info from you its real appreciated, if you can help update module it will be appreciated thanks 👍
Dean, Your a legend mate. I'd love for you to take a look at my N53!
you’re
Thanks for your video’s, just subscribed 👍 is there a way of telling if my n53 has had the software update? Cheers again
nope only I can tell once I use the software to check
@@BMWDoctor how to do you proceed to check software? thanks
@@BMWDoctor hi mate where are you based?
Just had to change the long life plugs on mine as it was rough idling. Mechanic said because it is direct injection go for the higher octane fuel (if affordable)
Is there anything you would check ?, like any sensors or anything ? Seems strange that out of the blue and on the start of the car it would break ?, plugs and coils are ok, but 5 and 6 down apparently and loud tick and shaking ?, if it is lifter stuck is this expensive job mate ? Is there anything I can check or do to try resolve or is it done ? Thankyou
Sounds like misfire from injectors imo. Did you fix it?
Hey bro can you leave a link to buy the N53 valve cover gasket
Can you please do video on the transmission also
Really hope you can help me!!! My n52 e90 has now been low on coolant twice in the past 2 weeks. Car isn’t smoking and there’s no sign of a leak. I changed the oil about a month ago and there was no sign of coolant in the oil either. Any ideas? Could it be the dreaded water pump?
🤓🤓🤓
BMW Doctor thanks for the solid answer!
How do I get in contact with you? Or how do I know if my n53 got the update or not?
I’d love to speak to you I’m building a 1000bhp z3 I’ve got a m52tu28 and a m54b30 I want to build it fully forged (rods , pistons , arp bolts ect but now after watching your vids not sure whAt to do may be go back to m50b25 non vanos but if you have time please call me I really value your advice
hey doc, i need some advice i hope you see this ... we have an x3LCI N52N (THA) bmw it was rough idling/missing, it would cut out at random times and rough changing gears to where it would almost push you forward in the seat as well. We took it to a mechanic here ... he checked it none of those things happened with him... he said he only got a light miss... diagnosed it and said it was the MAF and the rough changing was the cross in the rear driveshaft took it out the garage drove great engine wise only thing was the rough change in gears. Ok, so 3 days later MAF is changed.. still rough changing have to import the driveshaft... but now on top of all that...it is back to rough idling/missing even worse.. 4x4 light keeps blinking off and on and the engine light came on recently. If you can atleast give us some idea about this id be grateful.
brand of the MAF is OE .. so we arent playing cheap either... you have constantly drilled never buy cheap parts for this engine into my head
I am so confused. I wanna buy e90 325i 3.0. How can I know if its n53 or n52?

Hello,
I have a 2006 bmw 530xi. I keep getting the code P420 and P430. Lately my car is dragging and it won’t really accelerate. It’s really slow. Do you think it’s the catalytic converters or the oxygen sensor?
Thank you very much
if I was you mate take it bmw dealer let them have a look
Hello mate, I got an N53B30 on my car and I noticed that fuel consumption it went from 21-23 mpg to 14-15mpg could be because of the winter of something could be wrong with the engine. I’ve done full service in June last year ( almost 3500 miles ago ) spark plugs, oil, filters etc. I know on wintertime the consumption goes up but in my opinion, the difference is too much between 21mpg to 15mpg. Any suggestion? I got no errors everything looks fine. Many thanks, mate!
Nox sensor
Did you figure out what it was? Mines the same
Got an email I can contact you at? I’m looking to have my sap and o2 deleted and saw you coded Nathan’s 5 series for them.

Hey good evening @BMW Doctor I've got an issue with BMW 330ci 2006. It's got a battery drain so while I'm waiting to change the FSR on it I've decided to disconnect the battery. What's started to happen is once the battery is reconnected the car sometimes doesnt start, its turning over tho. Sometimes it starts then after a 10mins drive and turned off and you go to start it again it doesnt start. If you wait a while it decides to start again. Was thinking it could well be the fuel pump? But not sure.
Any ideas? Will be appreciated. Thanks in advance.
No mate that is (CRANKSHAFT POSITION SENSOR)
What is happening is when engine is COLD the car goes back into open loop
When the car is hot it’s in closed loop which means the car won’t start as it’s trying to use the sensor to start which it can’t because the sensor is faulty
@@BMWDoctor cheers mate will have a look in to that. Appreciate your help and time.
@@BMWDoctor is there any checks I can do to make sure its definitely the CRANKSHAFT POSITION SENSOR?
@@BMWDoctor also mate what make would you recommend to get? e.g HELLA, MEYLE? As not sure which ones BMW use as standard. Your help would be appreciated mate. Sorry for bugging you again.
My N53 engine seized about a week ago due to low oil pressure😢. It had some oil leaks back in march this year which I took to a bmw specialist and got it sorted. Fast forward in June I noticed the car consuming a lot of oil but this time on longer journeys like 2hours plus journeys. I had to refill the oil after every long journey. I contacted the bmw specialist who fixed the oil leaks back in march and he advised me to add an additive into the oil from Halfords. It was called stop leak. It was working okay until about two weeks ago the engine gave up on the M3 motorway. Had to call RAC to tow the car back home. The RAC guy said the engine had seized because he tried to spin the crankshaft and it was very still. He mentioned something to do with the timing chain as well. I’m probably now looking at an expensive repair or possibly an entire engine replacement
Sorry to hear that hope you can get the car back on the road somehow. Rotten luck
what happened?
2:27
I only know of a couple of people who had to get their HPFP replaced but they both said it only cost them £500 - £600 all in, including labour, rather than £1,300 - £1,400 just for the part.
Yh I’m seeing lower prices too..
Hi Dean, I bought my 2008 325 3.0L N53 MSport september 22 with a dead water pump so got it cheap and had it transported back to London, water pump and thermostat replaced, now it drives however it has many of the issues you've listed. got a bunch of new parts, just replaced mass air flow sensor, 6 x NGK sparks, 6 x Bosch Coils now it fires up and runs better but am still getting engine management light on afetr few minutes with high speed fan running and engine fault warning message on screen, next to replace will be 2 x VANOS, engine oil flush, engine oil replace, new oil filter - then take it to BMW for a full diagnostic check to see why she runs fine but the "Engine fault" message appears with a high speed fan then contact you for that software update.
Dean I've had BMW straight 6 naturally asperated cars for most of my life and to me "NOTHING BEATS THEM" I will crack on with your list of checks/fixes until my car is perfect because I know - once you look after these engines they pay you back 10 fold and the pleasure you get from driving a BMW - you just dont get from a Ford.
Tengo pensado comprar el mismo coche que tienes (325i Msport) 2008, pero me da miedo, es demasiado dinero que hay que invertir en esos fallos? Y son comunes los fallos o sólo mala suerte, el auto tiene ya 240000km 😅

Hi, can I get in touch regards an n53 update please?
Great video! How do I get the update done from you??
Many thanks
BMW Doctor hi. Have emailed you mate a while ago but not sure if you got it, no reply yet. Am desperate in your help with an update please? Is it still available? Thanks
HELP! This is a longshot but by BMW e60 is "lagging" when I hit some big bumps/speedbumps and the car acts like a crazed horse for a few seconds, I've changed the VANOS already but the problem is still there
Happens in LOW REVS! And sometimes it can happen while im cruising in 80kmh and I hit a tiny bump, feels like the car taps the breaks almost but we've tested all of the breaks and abs systems etc and its nothing to do with that
Hi doctor I need the update for the n53 how much ???
Great Video, as always. Very clear and informative. I do have two questions about it.I've got a N53B30 with almost 70k miles on it. My injectors were replaced before purchase. Would you advice to replace all the expensive parts ASAP ? HP fuel pump and water pump for example ? And what's the parts you mentioned at 9:30 ? I couldn't fully understand, I'm not British sorry :D
Thanks in advance :)

@@p.marinov2109 brilliant, thanks mate.
@@calummchale6145 also, your car is 2010, that means its 100% N53... the N52 fitted in the E90 gets replaced by the N53 after 2007 or 2008 i'm not sure .. so yeah, you got N53.
could be the Nox sensor
Hi bmw doctor I'm a new member How do I get to live chat with you? I have a problem with my bmw 325i n53 code p0401 egr 🤔 that I want to hear if you can answer me. Sincerely, Jimmi from Denmark
Is the n52 or the n53 better? Or there is no difference
N53 330i or n55 335i for e93 2011 ?
Will you say one should go for the N53 over the M54 or N52
No I wouldn’t I would say go for S65 or S85
BMW Doctor I am referring to the natural aspirated inline 6 options
Great work, info makes perfect sense. I have emailed you dean, is there another way to contact you? I’m in midlands Uk and n53 needs some tlc. Firmware update for rough run and 330i reflash after walnut blast and Intake swap.
👍🏻
I never got it mate yes mate it’s all done remotely for update mate and no brother no work undertaken outside of UA-cam sorry
BMW Doctor - nice one for getting back to me. Just resent mail. Is everything you do remotely pal? Like I say, I got most software and cable from shack, coding and live data is about my limit but need to get her smooth like she was, ready for sale this year.

How do I arrange for you to provide the update to my N53. Cheers.
How do can the upgrade
I have an -08 E91 with the n53 3liter motor and I'm having misfire issues in cylinder 3. Spark plugs (NGK) and ignition coils (Bosch) have been changed but it's still happening. After changing the coils the misfire didn't happen for 2 days but then reappeared. I have ordered new injectors but I'm afraid it won't solve the issue... Any thoughts on this? I will try to explain the issue in detail:
After starting the car there's no issues. I can drive for a good 15-20min before the symptoms appear. The check engine light will go on and the engine starts running roughly, rpm will start to fluctuate as well. When accelerating there's no power and the car noticeably shakes when slowly picking up speed. Idle is then also rough and rpm keeps fluctuating. Issue will not solve while the engine is hot, even if the car is turned off and back on the symptoms start immediately. Then the next day or after properly cooling down, the symptoms are gone again. As mentioned the only consistent error code I've received from the engine is P0303.
I believe the injectors are still the original ones or at least very old. I haven't checked myself. I used a petrol system cleaner, the kind you pour in the gas tank, and I feel like it improved the situation slightly, so I'm hopeful that replacing the injectors will fix the issue but still afraid it doesn't. Any advice going forward?
Update?
n52 vs n53 ? I am thinking between 525i (218hp) or 523i (190h). Which one of these would give me less headache and better fuel consumption?
You don't buy a 3 litre petrol car for the fuel economy...
@@SuperBobbster don't worry about what i am buying my car for, my money my choice
@@DjordjeSrpski i just got 39 mpg from exeter to essex in a e90 N53 325i with a faulty injector. If the car is running well i bet it would get more than 40 mpg. Turns out you can have good mpg and a fast 3.0 litre. thats why the stratified charge mode is such a pain to maintain!
I drive a F10 528i N53 and got 7,0l / 100km at 130kph. Once the N53 is warm it consumes only droplets of fuel. Its surreal.
@@tristanjager4112 I have a N53 325 Msport and I get similar mpg on the motorway even if engine management light comes on - but in town it sucks, still got a few bits to check off Deans list tho
Hey Dean
This is crazy ! I have the E92 325i (175.000 km) and I have gone through every single problem you just mentioned for the last 2 years, exept for one. The Injectors. I know thiese often make problems. I have used around 4500 pounds on all of thiese repairs so far. I am on the edge of just selling the car. BUT when it runs, I LOVE IT. It has only run 170.000 km. What do you think I should do ? Sell it or keep it ? :S
you've fixed all of the problems this engine might have and then you want to sell it? Why not check the injectors and make a decision after? looking to buy one with a bit higher mileage, hopefuly previous owner went through all of these before.
Hey i had my E60 recall done today by bmw and I'm thinking if u Can do the update for me because i have the rough idle still?
Yes I can mate but it’s not free mate
@@BMWDoctor I know just tell me how much to do it
Ok
Hello BMW doctor. Thanks for the videos ! I have a request : I am not an English native speaker, My average level of English is not sufficient that I follow your flow, can you just slow down a little bit (10 20% of speed).
I have to listen to your video many times in order to understand what you say.
Thank you 🙏
the same, he spoke really fast with no pause and huge irish accent ^^
I tried to use the subtitle but it's only in portuguese (?)
If a kind spirit could do a list of what problems he related on this video its will be nice !
sorry for my poor english in advance.
Not all N53's have the disa valves, 325i's with the N53 don't have it, only 330i
