2006 Audi A3 with 20T engine. Malfunction indicator lamp illuminated and car did not want to accelerate and went into limp mode. Took it to the Audi dealer where I purchased the vehicle new in 2005 and their analysis indicated a bad intake camshaft, bad high pressure fuel pump along with bad cam follower. Quoted work was $1000 labor and $950 in parts.

1. normal driving. 2. the camshaft follower on my high pressure fuel pump in my 2006 Audi A3 was punched clean through and the plunger on my fuel pump was eating away at my camshaft... I subsequently received no check engine lights, but had fuel cuts and boost cuts in medium to high rpms. 3. I had to buy a new camshaft, camshaft follower, and high pressure fuel pump. VW/Audi refused to help me because I am at 60,000 miles, even though my manual says the part should be check, and maybe replaced starting at 100,000 miles... they said that my aftermarket intake might have caused the damage by "over spinning the engine"... this is impossible, as the engine has a rev limiter, and I never have gone over 4K RPM yet, plus my "aftermarket intake" is nothing more than the stock intake, but wrapped in carbon fiber, with a K&N filter replacing the factory one.
