Smoking Mk2 Tdi At Start Up, No Power Loss

[hocky]

I have been offered a 2002 tdi with low miles that has a slight problem, i think.

on start up it smokeas a bit and then clears, no power loss but it uses abit of oil.

Is this a major problem? please let me know if there is anything i can check before handing over my cash.

thanks

hi there i know a little bit about tdis as i have had mine for 2 years now ,the first place you want to check is the pipes going into the intercooler ,its below the radiator if there is any oil coming from them its a sign that the turbo is on its way out believe me it happened to me and depending on the colour of the smoke its nothing to worry about also check for noise from the engine with your foot of the clutch if there is any vibration then it means that the dual mass flywheel will be needing changed as well and your talking 500 quid it also happened to me other than that they are a great car

good luck

Bloody hell thats a scary post :(

 

Whilst you are correct I'd like to calm a few people and point out that on modern TD's there is nearly always some oil in the intercooler and that its perfectly normal, if its pouring out then yes there may well be a turbo issue but a misting or small residue is perfectly acceptable and comes from the crank vent.

If the turbo oil seals are on their way out, you will have high oil consumption and a smoky exhaust, as this is where the oil from the turbo will go - the pressure in the inlet manifold is higher than that in the exhaust. The oil in the intercooler is the normal oil mist from the breather. This only leaks out if the intercooler gaskets or hose joints are leaking.
