W212 E350 CDI 2009 Oil leak from around turbo and fumes in cabin

[Tom Luscombe]

Hi all,
I'm new to the forum and am after some guidance if possible. I am loosing oil from my car which is leaving a lovely stain on my driveway and have been told that it is common for a seal to go around the turbo. I am getting quite strong fumes in the cabin through the blowers when standing still and was wondering if anybody has experienced the same symptoms? I am planning to change the glow plugs this weekend and if this is a simple enough fix will carry both out at the same time.

Thanks in advance,

Tom

Hello and welcome,

I've moved this into the relevant technical section for you

Welcome,

The oil cooler for the OM642 sits at the bottom of the engine V and is the most likely cause, if you are loosing as much oil as you say it needs sorting ASAP, likely cost 10hrs labour and a pittance for the seals. This is a known problem with these engines MB issued upgraded Viton seals (purple) to deal with it

Where do you live buddy , so someone can recommend a good MB Indy who is experienced with the job if it is oil cooler and seals , although it may not be .

The orange seal on the front of the turbo where the black batwing connects is a common leak point , but I don’t believe this would leak so badly that oil drips onto the drive .
If the oil has a red tinge it could be ATF

Thanks for the quick response. doesn't sound like something I could carry out myself then lol.

Oil doesn't have a red tinge, but is leaking quite a bit. I was told it could be the orange seal but as you mention, it is unusual to leak on to the ground from this point. I didn't know if the fumes were maybe a tell tale sign of something?

i wouldn’t recommend it the turbo and all the inlet and outlet plumbing plus fuel rails have to be removed. There are some good videos on YouTube showing what’s involved I would find a recommended Independent to do the job which should come in circa £700 plus the cost of a new oil cooler which most recommend

Hi, I live near Kings Lynn but Cambridgeshire side.

Bit out on a limb there , Alex Crow , Stowmarket would be my recommendation , maybe another member can recommend someone closer ?
Maybe get a local general garage to get the lower panels off and diagnose the likely fault first ? (£50?)

 

[Tom Luscombe]

Any Links to the videos on youtube by any chance? just so I can have a watch.

Thanks

Will probably go with a local garage to get a diagnosis but thanks for the recommendation and your time.

If it does need doing (oil cooler) , an MB Indy like Alex , will save you money overall by knowing the job and exactly what needs doing without guessing . Just my pennysworth .

^+1 I wouldn’t use a local garage there is a lot to break and some specialised knowledge helps a lot

combustion fumes in the cabin is usually either egr problem or injector leak.
