Competition winner - David Cowan - sprautos@gmail.com really common job this guys, if you own this engine you may of had this done, if you haven't there is a good chance you may in its ownership so will give everyone an insight to the job. Although this video makes it look very easy this is actually an 8 hour job! Hope you enjoy all the best everyone.For those asking this job with the turbo was about £2K
I had this job done a couple of weeks ago (leak was just a slight weep though) - it was picked up at a routine service. Turbo was OK. 167k on the clock. Hopefully it’s going to last a long time now! Great video, by the way - liked & subscribed 😀
Hi, great, first video I have found with the same surging, I seem to have this fault, is there a way to check the turbo itself to garentee it is at fault? I have the surge I have the pressure code and no eml. I must say though it is intermittent, doesn't do it every time you floor it, 50% maybe but it only happens on full send accel

This is one of the best engines Mercedes made after 2000 . I've had it in many vehicles including jeeps . As long as you keep it up with preventive maintenance and change the oil every 8000 km it runs and runs and runs ... as long as you're not scared to do some stuff yourself , it's not really expensive . Love it , recomend , 5 stars , 10 out of 10 .
@@MoesKeckeEcke Because he's parroting internet stories. The v6 is more sensitive to bad maintenance compared to the older i6, that's true, but that's about it. It's only issues are with the oil cooler and the flaps getting stuck, but the flaps can be cancelled with a resistor and the oil cooler can be kept an eye on. I've seen fleets of sprinters with this engine, all around 650-800k km and still running. Some oil leak here and there, but still ran strong. 1 went over 1 mil km before being finally retired, but not because the engine was bad, but because the truck bed and inside the cabin was getting really worn out.
@@MoesKeckeEcke It just has a few design flaws - blue emissions fluid chief among them - and lacks the durability and reliability of the old Daimler diesels.

Late arrival, I just finished this job on my new to me 06 ML320 cdi. The job itself can be fiddly, but it's all the cleaning that takes time. It was n good experience though. Thanks SPR for sharing vid like this making it possible for a guy like me to keep my ML on the road.
On the 8:02 minute when you replacing the old intake manifold damper links it is important to check if the manifold flaps have position sensors and if they do, the aluminum replacement needs to have additional steel pieces on the sides, similar to original plastic, to trigger the sensor when the flap is at max and min positions.
I so like your channel. Just, what I did to my 648 straight 6 cdi was removing the flaps altogether. The whole system is just to vulnerable. Oh, also disconnecting the egr. Life is good. But I’m living in Texas. Probably not possible in the UK. I feel so sorry for all the regulations you have to deal with. And just to get some more oomph I had my ecu remapped by Renntech. You got to love these diesels. Pretty rare in the USA.
Amazing! How tightly packed are all those components! If that was me, I would be looking for those washers and nuts that are making a bid for freedom. When I was 21, I tried cleaning and rebuilding a Stromberg carburettor on my Hillman Imp, without realising I had lost a washer down the inlet manifold - expensive mistake! Respect to you and your team!
When I done mine I removed the intake swirl flaps from manifolds with pliers and for turbo only the actuator I changed to the corect G227 I think code, purple gaskets are made of viton which should last longer ,not hard job but long time and yes change all gaskets clean all carbon and should be ok. Good video.
Great video, only just discovered your channel, now I’m addicted. Came across it as I have this exact problem, including the kangarooing when accelerating. Unfortunately for me you’re along way away. Really good to see your expertise.

Presumably you restock after every job? 👍👍👍 I too do many jobs on Rover 75's which the owners don't even know about , we find many faults which they were not even aware of ⚠️ They will only thank you when they have not been let down by the car 5 years later 😅
Yes we replace as we go. Haha we do all sorts don’t we that go unnoticed. But it’s a nice feeling for us when it’s back together knowing we have done what we can to make it the best we can.
Very informative, i really like your attention to detail top notch. I like your aluminium linkage upgrade for the swirl flaps and inlet motor replacement, i would not get the same attention to detail at my local Mercedes specialist. Great work!
2 other common issues I have found over the years is the PCV on the back left head faiils which allows the oil to travel down the pipe and into the "Y" pipe and then out of the large orange seal. The turbo ends up being changed thinking it's leaking oil when infact it's the PCV thats failed instead. The other one is the large green O ring in the inter cooler pipe at the top of the engine. It's either missing or not giving a proper seal.
Great video, only one I have seen which details the job and is uk based 👍 I had the EGR mapped out on my s211 om642, kangorooing went away, replaced actuator and exhaust back pressure sensor prior to that.
As a precaution you can place a piece of thin rubber under the plastic intake pipe, then if leaks occur the oil will exit down the outside of the turbo not leaking into the swirlmotor thru its connector. Also use the revised black rubber skal on plastic inlet.
The other " while your there" job to do is replace the O ring on the EGR cooler plumbing where it pushes into the inlet manifold. (7.10)The other end of the cooler from the flange. I had to do this whole job because that O ring failed and leaked coolant at a huge rate. Within a couple of days of first seeing a leak under the car the engine wouldn`t hold any coolant. This was an OM642 in a Jeep with only 140k on the clock. Good excuse to do the Oil cooler seals before they leaked so no big mess in the engine valley to clean up.
It's a systemic fault. The friggin o ring! Used everywhere in automotive today, designed to fail. The sheer amount of work caused by this feature is mind blowing.
I did all these jobs. my self. yes a biiiggg job. but the turbo is still running more than 90 000 km.. even when that turboproblem shows. but a restart and it all good for weeks...sometimes mnd. just love that strong engine. and love the torque.
Great video!! I have had the same done, but the car isn't starting now, just cranking , giving out all cylinder errors ... car was starting before the job .. any advice would be great ..
Very informative video, we have a C350 AMG estate with the V6 engine which needs stripping down 😕 so looking to sell it on as now have a replacement car, wish we lived closer to you as would love to see it on your channel!
I have the early stages of this issue on my ML350. I live down south but think I'll make the trip north just to have it looked after by someone who knows what they are doing!
I believe that from 2010, Mercedes started factory-fitting the new upgraded (purple) oil cooler seals to all new OM642 engines, so you should actually be ok. At least with the oil cooler problem described here!
A very strong engine, I had a 320 and now a 350, fortunately never had the oil leak issue (Yet), but the 320 did have the swirl flap issue! Lovely to see Sam and John doing the job properly. Most garages would likely only tie the flaps open and make do. I speak from experience! Keep doing what you do, and as you do SPR. See you in March. 👍🏻👍🏻
I have the same engine in my 2012 w204 and I believe it needs the valve stem seals replaced, how much extra would it cost, and do the heads need to come off to get to the valve stem seals. Thanks for the great video.
yup thank you , i got a clean 08 gl 320 with 170k in Canada , yes i can fix one day i love the car but no thanks i will sell it . put a catch can and the seal in turbo is newer , but i know what is coming , i don't want to deal with any of it , i will buy a Honda ridgeline for work need a box in the back !! thank you good job !!! ,, will changing the ail until i sell it ,, i will miss it greatly
Another excellent video, wondering now when my e350 cdi with 124k miles on will need that job doing😊 all was good when recenly b serviced my my local independent merc guys.
So glad my Merc mech advised me to avoid these engines and the v6 petrols. I’ve got a R129 SL320 straight 6. He told me to avoid the V12 as it would cripple me financially. Wish I’d bought the R129 SL72
M112 v6 petrol was a tank. 272 was ok. Yes I’m not a v12 fan either. Sl 72 is something very special though. R129 with a m113 v8 is the best combo in my opinion
This vid gave me flashbacks of when I did the cooler seals on my R class. It was fortunate that I did it during furlough as it took me a couple of weeks (a lot of that was waiting for parts though). I found the previous owner had done the resistor mod to delete the swirl flap motor. I took the opportunity to reinstate the flaps with a new motor and an aluminium rod kit. The previous owner had also fitted a chineseium actuator to the turbo but I ordered a genuine refurbed one from the states. One little mod I added was I added a shroud made from an old drinks can to cover the swirl flap motor as even though I was replacing the turbo inlet seal, I have only ever known them to leak. The shroud is shaped to guide any oil that drips down behind the flap motor and into the V. I'd be curious to know if you have a definite fix for the red seal leaking?
What does a turbo replacement run to? I have the bucking issue you showed in the vid. At much lower revs though. Have fired the parts canon at it, well everything except a turbo.
Great video, I have learnt a lot, I spend too much time watching your videos! At what mileage do you usually see these parts fail? I got a CLS 219 with the OM642 at 73k miles. Would it be worth doing the jobs in the video as a prevention at some point or just wait till one of them fails and do the whole lot? Thanks.
I have all the faults you’ve covered on my ml320, I had the oil cooler done a year and a half ago, at over a £1000 , but it would appear that my mechanic stitched me up it is now leaking water and a bit of oil not as much oil as before, so it’s lying in my driveway now doing nothing , being a pensioner I can’t afford to get it done again, I also had a new turbo fitted 4 years ago and the car started the kangaroo bit when I accelerated hard, but again couldn’t get anyone to diagnose the problem at the time, 🤷♂️🤷♂️🤷♂️ but thanks for your video very informative cheers 🙏👍👍👍
At first, I thought that you were going to be working on a failed radiator/trans oil cooler which was what put paid to my E211 270 transmission - good old Valeo rads! Enjoyed this one though!
@@sprautos The only time that I have ever traded in a car knowing that it had a fault - to the dealer that sold it to me 18 months earlier. That 2003 E class was the most unreliable car that I have owned!
I have a 2011 e350 with latest om642 engine 265hp. 250'000km and I changed only the thermostat I think the latest iteration I have is much more robust, with all these problems solved. But now at 260000km, I start to have some oil drops...oil cooler probably 😅 Will do it next holidays
I am in Texas USA and on the subject of the OM642, it would be great to hear your comments on the Bluetec Settlement. I know that MB had to settle in the UK and Europe so I'm sure you're familiar with this. Thanks!
An oil catch can circuit between CCV & turbo inlet would reduce substantially amount of oil that cascades down into valley from batwing turbo inlet seal. In my opinion, that is true source of most car om642's oil leaks. It soaks swirl flap motor, splashes all over turbo pedestal & then pools around oil cooler before draining through that weep hole in valley near bell housing. These issues don't really exist on 642s from Sprinters because they have a much better air intake system & larger oil pan that can accept 5 more quarts of oil. Every time I see another om642 oil leak video, I thank my lucky stars that I still have an om648 w211 on the road.
My car got the maff sensor and boost sensor and intake sensor and circuit fault… but Mechanic said I need new manifolds is that true or is it just the repair kit and motor?
Pure professionals. I am thinking of buying a 2013 CLS shooting brake 3l Cdi with 130k mile on her. Very well serviced with the cooler gaskets already done apparently. Just wondering would this need to be done again down the road, is this issue a design fault regardless of how well its serviced. Are these engines very reliable generally if serviced well. Cheers for the video guys it was a pleasure to watch.
Watching this makes me so glad I drive a car with the OM648, ok I have the SBC pump to worry about but these Vee config Diesels and not only Merc one's either are utter crap.
Very informative video well done! This engine was part of so many merc models and variations. Why do you think they went back to straight 6 ones? Is it just cost to make?
I’m really not sure, I’m Presuming it was emissions related, the v6 cdi was a nice smooth torquey engine. I wonder why they move on from many engines at times 😂🙈
Cut my teeth on these in the early 2010's....did sooo many exhaust manifolds on the 642 for metal pieces coming apart and mashing the turbo...That and the 272 balance shaft tear wearing off, Good old Crank/CAM correlation. I miss my days at a Mercedes dealer, Now I'm meddling with Audi...😂
I have this issue on my ML280cdi (OM642) I had the back pressure sensor fault, my dad who's an ex mechanic thought he'd sorted it. He's 74 bless him, if I'd known this earlier I wouldn't have had him do what he did to try and solve it. I'll be booking it in here and getting it sorted 😢wasted around £200 on parts as it's started again with the kangaroo hops 😩
Well it won’t all be a waste as if he has replaced the back pressure sensor we would have recommend that also anyway. Good on him for Giving it a go. And it caught me out the first time also.
Great work guys! Any chance of getting a list of parts /gaskets /orings like you have the magic folder listed here ? W211 owner with OM642 (225000miles ) perfect running condition never had the issue above but trying to stay in top of things always:)
@@BarrySims-w7p the newer type (Viton) seals were fitted on cars after 2010 but as previously mentioned they can fail. My previous Chrysler 300C with the OM642 engine had no problems but I have had to change the seals on my 2013 S Class with the same engine. Thankfully Mercedes didn't fit the dreaded swirl flaps in all the OM642 motors. My
Thanks for this awesome video with tons of valuable info, even the parts list! Question: Looks like you got a new turbo? So the stuttering was caused by a faulty turbo or was it the faulty/worn flaps? I do have that stutter every now and then, but only when I floor it. Normal acceleration doesn't produce that issue. Don't want to buy a new turbo if it's probabaly only the flaps. I'd come to you but living in New Zealand it's a bit of a challenge 🙂 (2007 CLS 320 Cdi, 220,000km) And yes, I have an oil cooler leak as well...
Awesome, thanks. I never could figure out what the problem was as the fault codes did not mention the turbo, most of the times it was exhaust back pressure. Thanks again!

Great video, only one I have seen which details the job and is uk based 👍 I had the EGR mapped out on my s211 om642, kangorooing went away, replaced actuator and exhaust back pressure sensor prior to that.
As a precaution you can place a piece of thin rubber under the plastic intake pipe, then if leaks occur the oil will exit down the outside of the turbo not leaking into the swirlmotor thru its connector. Also use the revised black rubber skal on plastic inlet.
Great Job,and forward thinking for sure
Looks like the owner has neglected a lot of regular maintenance
All the best cheers Frank
Great vid thanks.Tjink i ll stay with my w210 e320cdi om613 straight 6.Lot less to go wrong.
Great stuff, this video has been really helpful as my grand Cherokee has the Mercedes 3.0 v6 OM642. 👍
Glad it helped
Great video, as always. Very interesting and informative. Keep them coming.
The other " while your there" job to do is replace the O ring on the EGR cooler plumbing where it pushes into the inlet manifold. (7.10)The other end of the cooler from the flange. I had to do this whole job because that O ring failed and leaked coolant at a huge rate. Within a couple of days of first seeing a leak under the car the engine wouldn`t hold any coolant. This was an OM642 in a Jeep with only 140k on the clock. Good excuse to do the Oil cooler seals before they leaked so no big mess in the engine valley to clean up.
Great videos, find myself watching them even though I don’t have a Mercedes 😅
You don’t need one to be part of our channel buddy. Welcome 🙏
Excellent Job & Very Professional Gentleman !
New subscriber, due to the High Peak link
Glad i found you , like the straightforward ,understandable commentaries,
Thank you
Welcome aboard! And thank you. 🙏
It's a systemic fault.
The friggin o ring! Used everywhere in automotive today, designed to fail.
The sheer amount of work caused by this feature is mind blowing.
I did all these jobs. my self. yes a biiiggg job. but the turbo is still running more than 90 000 km.. even when that turboproblem shows. but a restart and it all good for weeks...sometimes mnd. just love that strong engine. and love the torque.
Great video!! I have had the same done, but the car isn't starting now, just cranking , giving out all cylinder errors ... car was starting before the job .. any advice would be great ..
Very informative video, we have a C350 AMG estate with the V6 engine which needs stripping down 😕 so looking to sell it on as now have a replacement car, wish we lived closer to you as would love to see it on your channel!
What's the issue with it, and what year? Looking for a 350 estate but want a face-lift model.
Cam chain we think, it’s a 2013, 62 plate
im so glad channel found it in australia,your customers must be so happy ,what a bout a branch workshop in sydney australia ,we need one.
I have the early stages of this issue on my ML350. I live down south but think I'll make the trip north just to have it looked after by someone who knows what they are doing!
Well done guys. Mine 2011 350 CDI CLS have done 83000 miles and I believe at one point, I will have the same problem.
I believe that from 2010, Mercedes started factory-fitting the new upgraded (purple) oil cooler seals to all new OM642 engines, so you should actually be ok. At least with the oil cooler problem described here!
I sold tonnes of these 642 intake port shut off motor bits when I worked for MB dealer, it eye opening to see how they fit to the car
A very strong engine, I had a 320 and now a 350, fortunately never had the oil leak issue (Yet), but the 320 did have the swirl flap issue!
Lovely to see Sam and John doing the job properly. Most garages would likely only tie the flaps open and make do.
I speak from experience!
Keep doing what you do, and as you do SPR.
See you in March.
👍🏻👍🏻
Great useful content ......I was about to buy a car with this engine ...........I won't bother now lol Cheers !!
Great video guys, it would be nice to know a rough costing for this type of job since it’s a popular fault. Gives us a heads up so to speak😂😂
This job would cost you £1500 without the turbo, more towards 2.5k with a new turbo.
I have the same engine in my 2012 w204 and I believe it needs the valve stem seals replaced, how much extra would it cost, and do the heads need to come off to get to the valve stem seals. Thanks for the great video.
Love your content, keep up the great work!
Excellent videos. Wich you were closer. Could you elaborate on the "turbo problems"-is it the actuator?
@@andrecornelissen7818 yes the kangaroo effect is the actuator failed
Real masters of their craft -😎 great to see
I'm actually in a market for an 06' E320 CDI with an OM648. I would never consider this one what so ever, unless you don't care about your money:)
yup thank you , i got a clean 08 gl 320 with 170k in Canada , yes i can fix one day i love the car but no thanks i will sell it . put a catch can and the seal in turbo is newer , but i know what is coming , i don't want to deal with any of it , i will buy a Honda ridgeline for work need a box in the back !! thank you good job !!! ,, will changing the ail until i sell it ,, i will miss it greatly
Very good video. Liked it! Also nice that you answered all the questions here! 👍
I try my best to I don’t know how much longer I can keep it up though 😂🙏
Goodness, I have this repair ahead in my 2011 W212...
big thanks for the link, ill go buy them and change everything on my glk 320. thannnnnnnks a lot.
Another excellent video, wondering now when my e350 cdi with 124k miles on will need that job doing😊 all was good when recenly b serviced my my local independent merc guys.
I think you should explain to the customers what you do and why you do it, like in this video.
They’ll appreciate you more for it.
Some do. Some don’t 😂 we try.
Great Video. Wish you were in Melb Australia to take care of my C32 AMG.
Cheers and looking forward to your channel.
C32 rare underrated car. I don’t know about over there but here there cheap as chips
So glad my Merc mech advised me to avoid these engines and the v6 petrols. I’ve got a R129 SL320 straight 6. He told me to avoid the V12 as it would cripple me financially. Wish I’d bought the R129 SL72
M112 v6 petrol was a tank. 272 was ok. Yes I’m not a v12 fan either. Sl 72 is something very special though. R129 with a m113 v8 is the best combo in my opinion
@@sprautos
My straight 6 Petrol has been bomb proof as half of V12 used in many other cars.
RE the swirl flap rod, great when you get one over on the Manufacturer who won’t just sell the part you need but the whole assembly 😀
Haha it is good your right. You get a nice feeling knowing you’ve saved a good few quid
This vid gave me flashbacks of when I did the cooler seals on my R class. It was fortunate that I did it during furlough as it took me a couple of weeks (a lot of that was waiting for parts though). I found the previous owner had done the resistor mod to delete the swirl flap motor. I took the opportunity to reinstate the flaps with a new motor and an aluminium rod kit. The previous owner had also fitted a chineseium actuator to the turbo but I ordered a genuine refurbed one from the states.
One little mod I added was I added a shroud made from an old drinks can to cover the swirl flap motor as even though I was replacing the turbo inlet seal, I have only ever known them to leak. The shroud is shaped to guide any oil that drips down behind the flap motor and into the V. I'd be curious to know if you have a definite fix for the red seal leaking?
Well done, there not easy on an r class, it’s probably the hardest one along side a Vito. So well done, plus you’ve addressed loads of other issues.
Awesome! Love the details covered.
Glad you enjoyed it
Great information. Very professional
What does a turbo replacement run to? I have the bucking issue you showed in the vid. At much lower revs though. Have fired the parts canon at it, well everything except a turbo.
Great video, I have learnt a lot, I spend too much time watching your videos! At what mileage do you usually see these parts fail? I got a CLS 219 with the OM642 at 73k miles. Would it be worth doing the jobs in the video as a prevention at some point or just wait till one of them fails and do the whole lot? Thanks.
I have all the faults you’ve covered on my ml320, I had the oil cooler done a year and a half ago, at over a £1000 , but it would appear that my mechanic stitched me up it is now leaking water and a bit of oil not as much oil as before, so it’s lying in my driveway now doing nothing , being a pensioner I can’t afford to get it done again, I also had a new turbo fitted 4 years ago and the car started the kangaroo bit when I accelerated hard, but again couldn’t get anyone to diagnose the problem at the time, 🤷♂️🤷♂️🤷♂️ but thanks for your video very informative cheers 🙏👍👍👍
Put Xado stop leak on radiator, it will help avoid oil and water mixture.
Great video and a Really interesting watch
At first, I thought that you were going to be working on a failed radiator/trans oil cooler which was what put paid to my E211 270 transmission - good old Valeo rads! Enjoyed this one though!
Yea used to do a few of those back in the early 211 days. Think I still have the test kit to test the trans fluid
@@sprautos The only time that I have ever traded in a car knowing that it had a fault - to the dealer that sold it to me 18 months earlier. That 2003 E class was the most unreliable car that I have owned!
Very impressed with this channel and the attention to detail. Thanks for your efforts.
I have a 2011 e350 with latest om642 engine 265hp.
250'000km and I changed only the thermostat
I think the latest iteration I have is much more robust, with all these problems solved.
But now at 260000km, I start to have some oil drops...oil cooler probably 😅
Will do it next holidays
wow, excellent job !!! may I ask where do you get the flap bars/kits ?
I am in Texas USA and on the subject of the OM642, it would be great to hear your comments on the Bluetec Settlement. I know that MB had to settle in the UK and Europe so I'm sure you're familiar with this. Thanks!
An oil catch can circuit between CCV & turbo inlet would reduce substantially amount of oil that cascades down into valley from batwing turbo inlet seal. In my opinion, that is true source of most car om642's oil leaks. It soaks swirl flap motor, splashes all over turbo pedestal & then pools around oil cooler before draining through that weep hole in valley near bell housing. These issues don't really exist on 642s from Sprinters because they have a much better air intake system & larger oil pan that can accept 5 more quarts of oil. Every time I see another om642 oil leak video, I thank my lucky stars that I still have an om648 w211 on the road.
you thing if they install a catch can, it will stop all that oil in the intake and going into the turbo?
Great job, very interesting
My car got the maff sensor and boost sensor and intake sensor and circuit fault… but Mechanic said I need new manifolds is that true or is it just the repair kit and motor?
Nice job guys
Will be taking my GLB to you guys for servicing soon
Pure professionals. I am thinking of buying a 2013 CLS shooting brake 3l Cdi with 130k mile on her. Very well serviced with the cooler gaskets already done apparently. Just wondering would this need to be done again down the road, is this issue a design fault regardless of how well its serviced. Are these engines very reliable generally if serviced well. Cheers for the video guys it was a pleasure to watch.
They have changed the seals, so time will tell
If it will need doing again down the road, it will be interesting to see.
🙏
Watching this makes me so glad I drive a car with the OM648, ok I have the SBC pump to worry about but these Vee config Diesels and not only Merc one's either are utter crap.
Very informative video well done! This engine was part of so many merc models and variations. Why do you think they went back to straight 6 ones? Is it just cost to make?
I’m really not sure, I’m
Presuming it was emissions related, the v6 cdi was a nice smooth torquey engine.
I wonder why they move on from many engines at times 😂🙈
Did you do a full clean of the inlet manifold, looked full of carbon, or is it not recommended?
We do the best we can with the time we have. If we cleaned everything until it looked brand new it would double the labour.
What was up with turbo?
Had same issue, changed actuator and was good as new
Great informative video
Cut my teeth on these in the early 2010's....did sooo many exhaust manifolds on the 642 for metal pieces coming apart and mashing the turbo...That and the 272 balance shaft tear wearing off, Good old Crank/CAM correlation. I miss my days at a Mercedes dealer, Now I'm meddling with Audi...😂
I have this issue on my ML280cdi (OM642) I had the back pressure sensor fault, my dad who's an ex mechanic thought he'd sorted it. He's 74 bless him, if I'd known this earlier I wouldn't have had him do what he did to try and solve it. I'll be booking it in here and getting it sorted 😢wasted around £200 on parts as it's started again with the kangaroo hops 😩
Well it won’t all be a waste as if he has replaced the back pressure sensor we would have recommend that also anyway. Good on him for Giving it a go. And it caught me out the first time also.
Great work guys! Any chance of getting a list of parts /gaskets /orings like you have the magic folder listed here ? W211 owner with OM642 (225000miles ) perfect running condition never had the issue above but trying to stay in top of things always:)
The list is to long 😂 if you search the web there are lists knocking about
Use heavy oil on om 642. Use 10w60 , or 15w40 weight oil minimum and you’ll be very happy with this engine. It’s after several engine seized.
At what mileage should the oil cooler seals should be done? Do they have a fixed mileage when they fail? Or they can fail any time? Big fan of 642
I haven’t found a pattern tbh, I’ve seen it at low miles and also high. So I would say it can happen anytime.
did mercedes fix the oil cooler seal? If yes at what year? Thinking of my 2012 R class
@@BarrySims-w7p the newer type (Viton) seals were fitted on cars after 2010 but as previously mentioned they can fail.
My previous Chrysler 300C with the OM642 engine had no problems but I have had to change the seals on my 2013 S Class with the same engine.
Thankfully Mercedes didn't fit the dreaded swirl flaps in all the OM642 motors.
My
On my second one of these engines. Current whip has 28k on it.
Are the later oil seals more robust?
Lovely wafty engine with plenty of go
It’s a great engine plenty of power/torque
I would like to think so but time will tell I suppose.
@@sprautos absolute Merc fan. Not feeling the love for everyone/hybrid ones at all though
Thanks for this awesome video with tons of valuable info, even the parts list!
Question: Looks like you got a new turbo? So the stuttering was caused by a faulty turbo or was it the faulty/worn flaps? I do have that stutter every now and then, but only when I floor it. Normal acceleration doesn't produce that issue. Don't want to buy a new turbo if it's probabaly only the flaps. I'd come to you but living in New Zealand it's a bit of a challenge 🙂
(2007 CLS 320 Cdi, 220,000km) And yes, I have an oil cooler leak as well...
Stuttering is from
The turbo actuator, we replaced full
Turbo due to the mileage on this one to make sure it was 100%
Awesome, thanks. I never could figure out what the problem was as the fault codes did not mention the turbo, most of the times it was exhaust back pressure. Thanks again!
Beware: genius at work.
😂🙌
