i have a 2005 octavia 2ltr tdi pd elegance. when i bought the car last year i believe it had been remapped to 170bhp. just recently its started spewing white smoke out the exhaust and smelling of oil (not sure if it is oil but thats the smell). there is no split hoses and everything seems intact after a general inspection so im believing it to be a turbo problem. if that is the problem then can anyone recommend a suitable turbo to handle the remap and would this bolt straight on?

 

thanks

I'm not sure if it is turbo problem (could be head gasket) but have a look on "sale" section, xman750 has lots of turbos which can happily handle that power. Please note that you would have to remap it again if you replace the turbo for non-standard one (still bolt on though).

can most turbos be bolted on if that is the problem or should i be looking for a specific one? why would i have to remap it after replacing?

No, the turbo has to be for your engine otherwise position, size or shape of flanges can be different. Saying that there could be a turbo from different car manufacturer (outside VAG) that would fit.

If you use standard turbo you don't have to remap it again but to use full potential of bigger turbo, new map has to be made otherwise it could work worse than with standard turbo.

Use search, plenty of topics about it.

thanks for the advice. im not much of a car boffin but im learning. smoke only spews out when im driving and accelerate. would this happen if it was a turbo problem? or if it was a head gasket issue would it smoke even when idling?
