Mercedes E-Class W211 OM642 v6 CDI. 3 most Common engine faults, oil cooler seals plus more!

[@sprautos]

Competition winner - David Cowan - [e-mail] 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

[@Orwic1]

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 😀

[@mikejennings7779]

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

@@mikejennings7779 you should have an exhaust back presure sensor, i would change turbo, back presusure sensor, and inlet motoro in one hit to cover a few common faults at once.

No way. The Inline 6 CDI was the last great Mercedes-Benz diesel. The V6 diesels suck.

[@MoesKeckeEcke]

@@closer71 why is the V6 the bad engine? because it is compact inside some cars or what? The inline 6 did have some issues right?

[@em4703]

@@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.

[@ILoveProjects]

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.

[@dn0682]

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.

[@JamesAllen300]

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.

[@MoesKeckeEcke]

an the big red seal that is on the Y to the turbo snail.. also usually a seal that gets hard or unsealed... not too bad this engine

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.

[@madmagyver9981]

[@TheDomin8rr]

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.

[@GazC]

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?

Hi, just find your video, very nice and clean work. I own a W211 E320 with this engine, and i have que same problem as shown at 1:25 but at 1900 to 2200rpm and sometimes only above 3300rpm. Its not always present, for exemple if i reset the computer i have no problem for about 100km... The flap motor is brand new but not the plastic parts on the inlet manifold, but the flaps moves well. The EGR is new as its pressure sensor. No fault exept the exaust back pressure sensor. After watching your video i think that my problem is with the turbo but i am not sure, and this part is very expensive (3250€ here) so... Do anyone had the same problem as me ? Do you think it could be the turbo ? Im struggling with this for month now, seen 3 mercedes dealers about it and they didn't fixed it at all (but sure took my money)

[@sprautos]

sounds like a turbo fault for sure, and also with you have a back pressure sensor fault which is a good indicator, for a cheaper fix you could replace the turbo actuator on its own, part numbers are very specific on those things so you have to be carful. good luck.

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.

modern cars have so many issues designs are poor from seals and wet timing belts to timing chain guides so so poor the modern customer is forced to go to garages and with so many ECU requiring restting once a componet is replaced but the big boys thrive on this

Great video but I hate the double click technique on the torque wrench.

Questions out the box. Can fabric a oil cooler out sited. And fuel filter out side. ? Love to know possible. For everyone. God bless 👍 Mick Australia 🇦🇺

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?

[@sprautos]

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 😂🙈

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:)

[@sprautos]

The list is to long 😂 if you search the web there are lists knocking about

[@sharonhogg6196]

Great video! Do you have the parts list for the UK at all guys? The one you have listed is US and the site does not show the W164 ML280 CDI on their list. TIA 😊
