Audi A6,my turbo is playing up, not giving enough boost, carwoods say it is full of deposits and may need replacing.If thrashing it does not help. any other remidies, I have found a few. car has only done 63k 2ltr .140 bhp need it running right before I have it remapped, again what bhp should be safe for engine
