View Full Version : Boost issues

05-28-2010, 10:36 PM
Okay I'm checking out a 98 1.8t tomorrow. The guy says he thinks it needs a new wastegate but is not sure. He says it boosts fine 1st 2nd and 3rd gear but 4th and 5th it fluctuates between 20-23 and will spike but won't hold. It has a K04-15.
Now I have a few questions (I searched and am still searching, but I'm looking at it tomorrow morning):
Is this really bad news, so bad that I should stay away from this car?
Could it be something more serious than the wastegate and he just doesn't want me to know?
What should I be cautious of/check tomorrow?
If it is the wastegate, how much is one for the k04 and how hard is it to replace?

Sorry I'm completely new to Audis AND boost.
