Glow plug torque,
Removal 20 Nm, (14.75 ft/lbs), 177 in/lbs. If you exceed this torque upon removal you risk breaking the plug off.
Installation 10Nm, (7.37 ft/lbs), 88.5 in/lbs
First part of the movie is pinpoint diagnostics. Then we get in the shop and fix the problem.
This is what I saw 2008 Jeep Grand Cherokee, merdesbenz ml320 w164
3.0L Glow plug diag and repair The most professional and detailed DIY video.
There are, as far as my limited search skills have determined, precisely two videos throughout the entire universe related to glow plug replacement regarding the om642 engine.
One of these videos is a 3 minute pile of crap, shot time lapsed, with goofy millenial music crap which teaches someone stupid like me absolutely nothing about changing the glow plugs.
The other video is this one, by comparison, a masterpiece of easy to understand information spoonfed to me as though I were a six year old, which is precisely the only way I am able to learn stuff.
I offer you my sincere gratitude sir! Thanks to you I can now approach the job at hand with confidence. I wish all the best to you!
Thank you, so much! Got P0674 and P0672 errors. Going to diagnoze with help of you great tutorial...
A First class tutorial. No ambiguity, well planned and logical, I'm especially grateful for the hands-on belt and braces approach. (if you're not) You would make an excellent tutor/instructor. Thank you.
I think your review of changing and checking out and glow plugs on this jeep. Vehicle was very well done, the information was at a good pace, and the information provided was complete without eliminating steps. This makes it all very clear for a novice mechanic. One item I suggest is a little more light on the subjects. Trying to see the glow plug down in those holes was a bit of a stretch with the light provided. All I know I gave you an 95 out of 100. Old-Rick
Thank you for posting this video. You did a very thorough job presenting the information and it was well produced. It's the type of material that makes UA-cam a great resource.
This tutorial just saved me $300 in shop fees. Thank you author.
What a quality video which helps enormously. Thank you.
I'm not sure what's most impressive - but your ability to work one handed is fantastic! :)
oh and the diags stuff at the beginning is very useful - thank you
I wonder why these 16 thumbs downs are given. Excellent video with excellent explanation. Thank you for your efforts.
This is one of the best video's on youtube. Thank you for posting! In this cold weather I am lucky to get my 08 JGC started at all. This weekend I will get the Gp issue fixed.
Thank you very much for making this video. Managed to diagnose and replace a faulty Glow Plug control module myself and no doubt saved a lot of money in labour fees at the local Jeep dealership!
That is the most comprehensive helpful video, and most of it done with one hand!? This guy knows his stuff have bad cold starting Glow time about 2 sec's not long enough I think.Thanks Dan
Thanks for the information. I was able to diagnose a loose connector after metering it out and thinking I had a bad plug. Thanks for taking the time to put this together to help out a bunch of strangers - I dont think a comment is enough to repay you for your time, however, it's all I got for you at the moment... wait.. heres some good karma! Sincere thanks from a fellow Jeeper!
Man I echo Brandons comment. Thanks isn't enough, here's more good juju from a fellow om642 owner.
Well done ! and no bullshit! love it. straight to the point. finally someone who knows what they are doing. I am so glad I found this video before any other BS short change video. This instruction is all you need!
very helpful, thank you. I was trying to acquire a jeep and was told it's difficult to maintain but with posts like this, I believe it will be much easier...
If I was you I would not get a jeep. Especially a diesel. I am not impressed with ours at all. The diesels are expensive to maintain and very expensive to repair if anything goes wrong with the engine. The fuel mileage is not very good due to the fact that it has a DPF system on it. The 4 wheel drive low on ours quit working and the only time I used it was to drive it up on the ramps when I did an oil change. I would hate to see how long it lasted if I actually drove it off the road once. Trail rated is what it sais on the side. My old Cavalier outlasted this thing. Just some of my thoughts.
I'm fortunate enough to be a diesel mechanic and can fix most of the issues myself. If I had to pay someone every time this thing broke down it would have cost me more than the initial cost of the vehicle and its only got 160,000 km on it.
Miria, I have had to spend money to keep my Jeep GC in tip top shape, but I do really love it and haul lots of weight with it and recently made a custom mount for my snowbear snow plow blade. sharock23c may not have had as much luck with the 4WD as I do, but I have not had issues with my 4low or 4hi yet (knock on wood). I take my GC into the woods every time I have a chance.
Helpful video with accurate, concise and thorough commentary. Good work!
What a great video, thank you so much for sharing. I just bought a 2008 from an auction this summer. Iam having issues with it starting, so this video is going to help me big time.
So number 2 is the front driver's side, not middle passenger side. I'm so glad I watched right to the end with the diagram. Thank you for all the info.
THIS WAS REALLY GOOD - YOUR PEDAGOGIC AND METHODS ARE SOOOO IMPRESSING -- THANKS MAN!! (ONE WHO NEVER MAKES COMMENTS)
Thank you so much for making this video. I was able to diagnose and repair mine with little effort. The Module was broken. I needed 10 Minutes to Diagnose and a week later again about 10 Minutes to replace the Module. Start without any problems now. Thank You so much. Greetings from Switzerland
Thanks for taking the time to make this video. Very helpful to watch before undertaking any work yourself.
Best repair video I have seen!!!! You should be proud.
Thanks so much for a very informative breakdown of the GP system
Great video. What looked difficult is actually pretty straightforward after listening to you and watching you go through the steps. I admit I was dubious about your diagram at 2min showing the location of the glow plugs but I had a P0675 error code and the number 5 cylinder glow plug is where do show it to be.
You helped a lot of people with this amazing video.Please post more.
Good job, very concise! My 2007 JUST started showing fault P0670 I now have a good idea of how to track down issue. Thank you!
Great video. Thanks for taking the time to help us out. Much appreciated
Thank you for making this video. I just bought my 3rd vehicle with this engine.
If you ever get the hankering to change out a starter motor, water pump or alternator on the om642 and film it for us, I sure do look forward to watching anything you'd put out. Thanks in advance, this was well worth the subscription!
Bob MccKenzie I would too for sure
Brilliant video..clear and concise..well done from the U.K.
Amazing info! I should have trusted myself and done this module swap p1649, but I paid $650 to have it diagnosed and repaired , on my '07, at the local shop. I did, however, use this video to diagnose and repair the glow plug on my '08!! Two big thumbs way up. Jason in Winchester, VA
Thanks.
A great movie. Very Professional, helped me a lot. Thanks for that.
Great video. Thanks for all the detail. There was another video that additionally demonstrated removal using repeated clockwise-anticlockwise force on the plug, which seemed to be a good technique. May be worth considering on top of the penetrating oil and hot engine advice...
Me too, man. Excellent video. Very well done. Helped me diagnose and replace a bad cylinder #5 glow plug. Many thanks.
Excellent video, a million thanks. I have the same Jeep with the same problem.
Brilliant video. And a great choice of music😎😊 many thanks
An excellent video, everything well explained and showed. More video please!
Wow very good video, doing my glow plug right now!! tx for the gread info.
Great video, very informative clear and precise 👍👍👍
Hi. thank you for your work. Video is great. I am troubleshooting JK crd 2.8 . Take care.
Thanks great video saved me a lot of money
Great info, thanks for your effort in putting it together.
thanks for the video- just changed out #2 and 6 today, the reference material is a big help. Didn't do an ohm test, the Jeep has 75K miles on it, starting to change them out as they go bad.
Paul Brenner how do get out glow plug 6¿? Its covered by a bracket or something
Great video - thanks. The driver side/passenger side for us crazy Brits is a little different!
Sharock you r good.Clear explanation. Great video.
Thank you for your expert opinion and excellent guidance. I have six new plugs and control module ready to go, same vehicle. My fault code is p0670. I intend having a crack at this tomorrow.
Very good information. Thanks for it.
Thank you. Very informative.
Thanks for the excellent video.
Very good video. Thank You very much.
Excellent info many thanks.
Great video... one handed too. That takes talent but you should consider a head mounted camera. I am no where near having skills to play around in an engine but at the very least this video will has helped me understand what's involved in the job. Great work.
Great Video! Thanks
Very helpful many thanks!
sharock23c, great video! Found a lot of great service info for my 2007 GC Diesel on UA-cam. I'll subscribe to your channel. Keep up the great work.
Thank you will solve my problem!
I'm dealing with this today, glow plug out on cylinder 1 on my 07 CRD. I have to watch again because I thought I saw you want the engine warm when doing this.
Good work
TANKS MI FRIND¡¡¡ YOU SAVE ME REGARDS FROM ARGENTINA ¡¡¡¡¡
wow you are good.this is for the mercedes 3.0 v6 engines aswell people
Hi, thanks for the informative video. When you take the foam off the driver's side, there's 2 hoses that need to be moved. What's the smaller one with the brass-looking plug in the end of it? My Jeep doesn't seem to have that one.🤔
This was fucking awesome one of the write/work video I seen extremely help to us, thanks so much Jeep dealer wanted over AUD $1200 instead it cost us $170 thanks
Thanks so much for a great video. Is there a way to test the data. I presume that is from the ecu. All the tests as per your video on my car is perfect but no power getting to glowplugs. I put my multi meter on a glowplug wire and earth, switch on and wait for indicator light to go off, but no voltage in that period. Can you please advise. New module
Awesome video! I just have one problem. How did you remove the glow plug connector #6? What tool did you use? It is so tight back there, can barley get my fingers to it. Can't squeeze to get the connector off...
Thanks so much !
Hi,
Great video. I would like a video like that for every issue I have with my car.
My issue is with glow plug number 6. But it is very difficult to remove it. How did you do to remove it? Do you have special tools, or did you remove other parts?
Thank you in advance.
all the diagnostics can be done cold. you only warm it up when taking out the glow plug. and I try to take out the plug before I warm it up and if it don't come then I warm it up.
Thanks.. really great help and very educational :-) Nice commenting and not too fast . I will subscribe for future needs with servicing my Jeep Commander 3.0 crd :-)
I had no idea the commander came with a diesel. What year?
This was awesome!! Thank you! My new mechanic wanted to charge me $2000.00 just for the module plus plus.. GRRR Being a woman has draw backs. People like you make it easy to not be a Stupid Woman too.. LOL I found my parts way cheaper and will now test and replace what Actually needs it thanks to you :))
Hugs and Kisses from Canada
$2000 for the module seems outrageously expensive. Even from the dealership there not that much. Where was this mechanic from? You could change the module and every glow plug including diagnostics for under $2000. I have worked a few different places and dealer ships and seen a lot of customers get ripped off. Even I'm scared to take my car into the dealer ship for the bullshit they will try pull and I'm a master certified mechanic. I'm making these videos so people can see what is actually involved in the diagnostic process and can hopefully do some repairs themselves and not have to go to the shop.
I am in Kingston, ON Canada as is he. I am very glad you make these. Found the part for 200.00 canadian and the glow plugs for 39.. He was quoting from the manufacture supposedly and claimed no others were available. Glad I got a back bone Finally and did some research.. that was at X-mas. Jeeps been sitting since :((
Much Gratitude for the time you put into this
bronwynjj, if you are in the GTA area. Check out Peel Chrysler (Mississauga) and request Reynold to look at / work on your diesel. They have always been great to deal with. I do most of the simple repairs myself to save some money. But they do the major stuff.
Cool Thank you and Love your Pic :))
Let me know what you think of the video.
+sharock23c I'm having this exact problem with my 08 Diesel. Reader shows 1850 VPW. Module Voltage. Does this mean the control module is faulty? Or should i go through all the steps in the video? Great video by the way.
+Grogor1 1850 vpm would be the protocol used to communicate with the ecm. there should be a fault code like P0xxx or P1xxx. But if it's a module power supply lost fault and there is power on the large wire I would suspect the module. I have a module I split open and it burnt the wires off inside. If you have lost power on the small key power wire you will get a glow plug module lost communication fault because the module is not powering up. Hope this helps.
I took it to a friends shop, was a fault code exactly like you said, part is ordered, should have it fixed in a couple days. Thanks so much.
+sharock23c Great video. Probably the best Jeep CRD specific video available at the moment. Used it to trobleshoot and sort out my GP system. Ended up replacing GPCM after fixing it with solder. Short term fix, but eventuall yneeded new GPCM. Had to change GP #4 as well.
Question: Is the grey Jeep yours? Any idea where the grill guard was purchased, or where to buy one?
+shanghaitheory. The grill was on it when we bought the jeep. I went and checked to see if there is a name or label on it but there is nothing. I would think that some one like grand west would have grills guards.
Great video. The diagram at 25:48 is wrong so that is why your codes were not making sense, #1 is the front passenger, #3 is the rear passenger, #4 is the front driver, and #6 is the rear driver.
очень познавательно Большое спасибо авторую
Hello, thanks for the video, i have a p0670 code, ecu glow plug, circuit open, any idea? sorry for my english im from argentina
How do you prewarm the glow plug on these jeeps
tks so much!
Great Video!! Unfortunately I didn't get too far. Pin 6 ground measured 8.7 ohms. Not sure where to go from here as the engine harness is Brand New! Ignition switch is new. Any thoughts suggestions would be greatly appreciated.
If you pause at around the 2 minute 8 sec mark, it shows where the ground wire from pin 6 is attached. Might be loose or a dirty connection. Good luck.
fantastic
So I know this isnt about the glowplug but I can't find the amplifier to the sound system for this exact model. Does anyone know where it's at?
Great video, very explanatory.
Had the mechanic already replace the glow plugs in my 2009 Grand Cherokee with what looks to be the very same motor. I've already ordered the module as we still have the starting issues - hit and miss but more miss than hit now.
I can see how to replace the glow plug module from your video. Thank you. I'll do that and it should be fine; cross fingers.
By the way, what is the diagnosis software you're using and is it available to the public or do you have to be a mechanic to get a hold of it?
I use Appcar diagnostic software running on a laptop, and it shows these codes. Cost me about $50
You do a good job why don't you do more of these? I have a 99 Mercedes E300 that needs glow plugs and maybe a module. The battery is under the seat is it necessary to disconnect the ground cable to work on. Thanks
By the book yes. But most people don't.
Great video man. Not a lot of info on this vehicle out there. I’m thinking my controller is bad. Shows two cylinders are bad. Checked them both and they seem fine. Although every pin shows .6 ohms. But the others are fine. Faulty volt meter?
If you tested each glow plug pin and get the proper resistance then the module is more than likely bad. The original modules were not very good. If you are worried you could try and swap a glow plug from a bad hole to a good hole and see if the problem moves.
@@sharock23c Just as a heads up for anyone else. I checked the glow plugs and they tested fine. I tested the wires to the glow plugs and they were fine. I also made sure there was power to the module and that was good. It was a bad module. Thanks again for this video.
Hey sharock, are you sure about pin 6 being the ground? When I check for voltage on the module pins(with just the power plug connected to module and neg meter lead to battery ground) I have power on all the glow plug pins plus on pin 6 but not on pin 5. Are you sure it's not pin 5 that is ground and pin 6 12v?
I looked up the wiring diagram at work just now. And yes 6 is the ground. If your seeing power where there should be ground I would double check battery connections, eng block ground, chassis grounds. I would suspect there is a different grounding issue that might be a root cause.
how reliable are these mercedes 3.0 diesels compared to other diesels ?
Hi nice video I pull my glow plugs on my jeep and the tip of the glow plug has some oil can you tell me if is ok , thank you
Renato Olivares I have the same problem can you tell me if it is a bad problem thanks Doug
hello you video is amayzing. it s really clear and it help a lot. ty! i have a quest can u pls tell ,e from where u bought that aswomew bull bar pls?
+Inf inity. It was on it when we bought it. Its more just for looks. I don't think it would protect the car much if you were to actual hit a deer. Ill look into it and see if I can find out who makes this one.
ty
+Inf inity. So I looked into it. "www.carid.com/2008-jeep-grand-cherokee-grill-guards/" The very first one at this web sight looks like the one we have.
great: d ty .. my problemm came from glow fuse module... 3 pin from passager side dont worn so 3 fuse glow dont burn on that side..ty so much for all. it really means a lot to me
Hi i can see the you turbo is not leek oil what do you do to stop the leek thank you
The fault codes you have at 1m59s are wrong, at least on my 2008 JGC Laredo. P0675, is cylinder 5, and is in the location you say is at P0673 in the diagram at 1m59s. The diagram at the end of the video, at 25m45s is correct, cylinder 5 (P0675) being passenger (left side you facing the truck) side, closest to the firewall.
Is this particular year and model Grand Cherokee, with the Mercedes diesel engine known to be a good Jeep or a notorious lemon? They seem like an interesting build and I can't find an overwhelming amount of info on them.
Its a nice vehicle to drive. The fuel milage averages around 13-14 MPG. Not that great as my one ton dodge pickup with a 6.7L diesel gets 14-15 MPG empty. Since we got this jeep. Its needed a TCM (transmission control module) that also needs to be programmed by the dealership. So that problem the dash would light up and wouldnt shift gears. Next the ECM went. Then the Glow plug module. Have done 2.5 sets of glow plugs. The jeep we got is one of the "trail rated" ones (I have little faith in these off road packages). Being trail rated the steel fuel tank is protected by a plastic tub. This tub holds all the dirt and little rocks and moisture around 3/4 of the tank and is the perfect combination to rust it out in no time. Then it threw faults for turbo boost pressure issues. Ended up being the turbo actuator that controlls the variable part of the turbo. This part is not sold separately from the dealership and requires the turbo to be changed. At a dealer cost of $9800 for parts. I found an actuator on amazon for $180. Installed it 3 years ago and works great. I want to make another video on this. Then usual stuff that all vehicles go through. Our neighbors have the same jeep same year and model with the 3.0L diesel. I am a mechanic so I fix there stuff to and it has had the same problems. But with there jeep the turbo compressor inlet pipe has a silicone seal which comes apart and damages the compressor wheel. Then its new turbo time. Dealership price for the turbo at the time was $9800. Plus labor. I called alamo turbo and i think it was 4500 from them. Call in a few favors and got it for 2500. Still excessive as we put turbos on semis at work with 15 liter engines for $750. There is an updated inlet pipe from the dealer for this problem. I like the jeep but if i wasn't a heavy duty mechanic that can fix my own things this would have been a horribly expensive vehicle to own. I would stay away from a diesel jeep unless you understand these inside and out. Just my experience. Hope this helps.
@@martinolsen6369 What kind Of Milage were you and your Neighbor looking at with these problems setting in?
What should the voltage at each glow plug connector be? My oem module shows 6.9 volts where the beru module shows 1.9
As far as I know the glow plugs are powered by a duty cycle that changes. Not just a constant voltage. So trying to measure DC voltage will probably give you erratic readings. But I could be wrong. I havent actually checked to see if it is duty cycle or not.
Hi my diagnostic machine is saying number 1-6 glow plugs and very hard to start, do you think it would be the module at fault and not all the glow plugs? Thanks
If all 6 were actually open at the same time I would be a little worried that the module has a problem and burnt out the glow plugs. But it could be that maybe 3 out of the 6 are bad and they want to change all 6. If the glow plug circuit is open there should be a fault code logged for each one. Then the wire for each one should be checked to see if it can hold a load. If it can and the glow plug is good then the modual is at fault. I cut one of the modules open and found the tiny wires inside melted off that supply the power to the glow plugs.
Thanks for the reply, so I have changed the glow plug module and still the same, my diagnostic machine is coming back with 1 to 6 glow plug fault code (separate codes) so I think next is to change them all, also when I try cracking it I can see smoke coming from glow plug 1 and 2, what do you think they could be at fault?
Is the last glow plug Considered number 6 ? Because that's the one thats bad on mine. And the glow plig module supposedly.
So if you got a fault P0676 then this is the cylinder on the drivers side closest to back of the eng. Cly 1,2,3 are on the passenger side front to back and cyl 4,5,6 are on the drivers side front to rear. If you go to 2:00 min in the video there is a pic of what fault is associated with glow plug location. Hope this helps.
@@sharock23c yes thank you.
How can access to glow plug #6? I saw its buried with a harness cover or something. Looks like turbo collide with socket spanner
Hi, me again. With power on and testing directly on the module I get 9.2v on all those pins all the time.
If the data line is disconnected then it should throw a fault for unable to communicate with the glow plug module. If the car is warm enough it wont cycle the glow pluggs. I wonder if there could be a problem with a temp sensor and the car thinks its warm enough and does not need to cycle the plugs.
@@sharock23c Thank you so much for the reply. Wouldn't a faulty sensor give a code? No codes on my carr
It might. We call them in range faults. So if the sensor is reading between a set parameter it wont throw an actual fault. If you can get a hold of a scan tool and see what the reading is. We let the vehicle sit over night and then make sure all the temp sensors read the same. Then if you got one reading 30 or so deg above the rest then you know to check that sensor and its circuit.
@@sharock23c Thank you so much again. Will see what I can do. Btw I am from South Africa
When im done work today ill go over the wiring diagram and see if i can come up with something.
Hey!
In your circuit diagram you show a fuse between the module and the ignition. Is there actually a fuse and if so, where? I cannot find any fuses on my 2007 3.0 that are glow plug module related.
James Mapledoram I don't know exactly which one it is but it will be in the Fuse box that's under the hood. most fuses protect several circuits but they tend to only list one or two in the manual. Need to get a hold of the actual circuit diagram. I'll see if I can find which Fuse it is tomorrow.
Hey thanks I'd really like to know which fuse!
Troubleshooting a U0106 (communication with Glow Plug Control Module) on a 2007. Started occurring right after replacing the fuel filter. So, we already checked / cleaned the ground wire. We replaced the GPCM as well. I suspect it could just be a fuse... we are getting no power to glow plugs at all.
Thanks! I'd really like to know! Looked all over for a diagram but only finding the ones for the Wrangler. We are getting the U0106 (lost communication with GPCM) right after replacing the fuel filter. We checked the ground wire near the filter and cleaned it. We replaced the GPCM as well. I suspect fuse maybe since there is one... getting no power to the plugs at all.
PS: You have the most informative video on the net for this vehicles GP circuitry. :) Thanks very much!
James Mapledoram So I found a diagram. It sais that Fuse 43 in the under hood Fuse block powers the glow plug module on pin 5. it's a 25 amp Fuse. It also power the water in fuel sensor pin 2, crank case vent heater pin 2, intake swirl servo motor pin 2, EGR valve pin 2, boost pressure servo motor pin 2, and pin 86 of the fuel pump relay, and ecm pin 3. I would check for power at the crankcase vent heater and if you have power there but not at the GPCM pin 5 then there has to be a broken wire somewhere on the way to the module.
I am having p0675 p1648 codes coming up. Have replaced both the glow plug and module and tested the connections between. Erased the code but it comes back on shortly after or the next day. Any suggestions would be awesome! Thanks!
so p01648 is an internal glow plug module fault. double check your power and ground circuits. if they test out OK change the module.
thanks for responding! we didn't check power between the module and glow plugs. we also replaced both the glow plug 5 and the module.. Still the engine light came back on. frustrating
I'll. do a little research and get back to you tomorrow.
Thank you!!! I appreciate it!
@@sper Hello, I know it's been 2 years but if you remenber What happened to your vehicule in the end ? what did you do to fix it I have the same error codes ...
Very good video but any open will not show high resistance... it will show OL
Peter Geralis. Not all ways. One side could be open and the other could be shorted to ground or other wires with shitty contact causing high resistance on one side. Just depends on what side is checked. An open is high resistance. Its considered infinate in the automotive world. It's that these shitty automotive style multi meters don't have the range to measure it.
sharock23c ok misunderstood not the whole circuit, but one wire yes. I also under stand that even a really good meter can't really accurately check resistance on anything lower than 1 ohm. But if you unplug the gpm and the wire had chaffed to an open and backprobed the suspected cylinder it would be OL. I meant to specify that.
It was my understanding in the beginning you said glow plug 123 was on passenger from front to back and 456 was on the drivers side front to back. The diagram at the end is incorrect showing the glow plug numbers from my experience.
the difference in the numbers is the cylinder location and how the glow plugs are numbered by fault code. there not the same.
But I'll book and review the movie and correct it if I made a mistake in labeling something.
I think the cylinders are mislabeled as well. This is not a gas engine with timing firing and I think Jeep is so used to alternating cylinder numbers they put this in the manual as well and whoever wrote it. Thanks for a great video. I had 2 plugs together come up with a code at the same time which is odd as I would only have 1 at a time. I going to follow your testing to make sure it is actually the plugs. I keep spare glow plugs but not the module. I have now 197,000 miles on my 08.
Hi first I wanna say ty for your help in the past. I asked u about glow plugs in past from my inf inity account. I think a have a new problem with my jeep gk 2008 3,0l. În last time I seen I lose oil u Der the car I was in a service the figure it out its come from oil cooler. So I go I service they change all seals from turbo from cooler oil. From everywere. They cleaned my gallery and hole place from where cooler oil stay. Then they put everything back. When all was done, I start the motor it was smoke.....but car start pretty good. I run the car all day it works... but the next day when I wanted to start the motor car didn't start no more. I hear the motor want to start but it die in few seconds. I call the guys from service a guy come to my parking place and he start my motor with a spay. He said problem come from my egr valve bcz it s durty. .... and idk what to think about. Befor this cooler oil changing. My car start good every day. He told me about a sensor witch can get durt and he also said if I wanna start motor to take out the water sensor...... do u think they can be right?
Good, but you never show the pin-out of the module connector. [Later edit - it is @1:34] @25:54 diagram* is practically unreadable and does not relate the pin numbers to the layout anyway. @12:20 you have a diagram but frustratingly show only a corner! From there you talk though one-by-one but we can't really see as your hands are mostly in the way.
* I'd like to know where you found the diagram. I have full service manuals but can't find it, nor the pin-out - Page 8W-80-72 says it's not available!
Module pin out is at 1:34.
The diagram at 25:54 is just component locations not wiring pinouts. At 12:20 the corner that you see is for me while I was making the video and is the one at 1:34. All the diagrams are clear for me on a laptop or desktop computer. not so good on a phone which I assume you are using. I figured the whole sys out on my own with no manuals. Fairly simple. Next.
@@sharock23c My apologies, @1:34 is just what I wanted. I had watched through but when I went back to look for the pinout I somehow missed this. I've added an edit to my OP in case I mislead others. :-) Meanwhile I have tested mine, working by logic, and 2, 5 and 6 are u/s. 6 looks a swine to reach.
Hi nice video I pull my glow plugs on my jeep and the tip of the glow plug has some oil can you tell me if is ok , thank you
It's OK. The thicker part of the glow plug from the tip to the threaded part at the top will usually have oil on it.
