Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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... …”

NHTSA complaint #10283048, filed 2009-09, 60,800 miles

“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.”

NHTSA complaint #10394205, filed 2011-04, 69,983 miles

“Engine coolant line flange failure. Causes engine coolant to drain from vehicle .the dealer indicates that this is common on the 2.0 engines. Part unavailable in the us (on back order). The car was parked, luckily. Could have been a major expense if on the highway. Drained within several hours while parked. If this is an issue, why isn't Audi replacing this with a metal flange instead of a plastic one?”
