[V10tdi Slovenia]

Hello new mebmer here.
I was driving the other day with my 2004 Tuareg V10TDI. Engine was taken out and turbos were replaced 1000miles ago.
I was pulling out of a gas station on motorway then suddenly i heard quiet whining noise and huge pile of thick white smoke out of exhaust. It was smeling like engin oil.
Car didnt loose any power but we stopped the car and loaded it on a trailer. The other day i took off Intercooler lower pipe and on both sides there was deecent amount of engine oil.
Any clues.
Tnx

Crankcase breather possibly? Were the turbos new when they were replaced? Worn turbo bearings can allow oil to pass and in severe cases become fuel for the engine meaning it can't be stopped. That's pretty extreme however...

Turbos aren't completly new only turbo cores are brand new. U sure abouth breather there was a ton of smoke comming out of exhaust but i hope i didnt ruined the turbos.

Crankcase is normally a gradual thing but from what you've described something has failed causing oil to be burnt in the engine somewhere or for unburnt fuel being passed into the exhaust. Worth looking at injectors maybe? Have you plugged it in for a scan?

 

[chaser]

Some oil mist from the crankcase breather condensing in the intercoolers is normal. They should be checked occasionally particularly with higher mileages.
Should also be checked whenever turbos replaced especially if replacement is due to seal failure.

You don't say if you still have the problem or is the car in use again? Are there any starting problems?
White smoke from a diesel engine usually denotes unburned fuel so I would look into the possibility that injector seals may have failed.

Tnx guys for all advises. No lights turned on on dash but i havent plugged in the tester yet. This is the photo of oil that came out of IC pipes

That looks to be more than condensate to be honest. Be interesting to see what the outcome is of plugging in with regard to injectors.

 

[V10tdi Slovenia]

Tnx will plug it inn and keep you guys updated

Okay i got the car on tester. Only thing that stood out for me was code: P0300 random/multiple cylinder misfire detected.

Sounds like it may be injector related. Someone more clever than me can chime in but I think there's a way of checking the correct function of the injectors through VAGCOM.

Okay so i have an update.
There was allot of oil missing and i put new oil inside. Then i started the engine and it was smoking badly from left exhaust pipe. I ran it abbout 2minutes and it consumed allot of oil so i think one of the turbos is blown

I tink that something is nood good wiht turbos for sure👌

That is, as we say, fooked.

Yep, @NoobyT has it spot on. For there to be that much oil exiting both exhausts points to a serious issue. Sad day but hope you manage to find a fix soon. It's a nice looking machine...
