Does your TDI feel tired and sluggish? Is it hard to wake up in the morning? Does it smoke a bit on takeoff from stop lights? Is it burning more fuel than it used to.
My Golf TDI had all these symptoms, but they developed so slowly that I hardly noticed. Then, when I was having another problem fixed, my mechanic pointed out some fraying on the vacuum hose leading to the turbo. It turned out that he had time to replace all my vacuum hoses.
All I can say is, Wow! It was like upgrading to a bigger turbo or race nozzles. Instantly, way more power than before. Instantly, no hesitation at all on acceleration. No exhaust smoke. And fuel economy -- before, I was averaging 37-39 mpg in late August and early September. But the last three tanks have averaged 44 mpg, with no change at all in my driving mix or pattern.
So, if your TDI is more than five years old, and if it doesn't seem to have the pep that it used to have, it's possible that replacing the vacuum hoses connecting all the various sensors will make your TDI run like new.
