Verified

2.0L turbo charged engines may develop a hesitation on acceleration and/or illumination of the Check Engine Light due to a failed high pressure fuel pump or a worn camshaft follower or camshaft. Our technicians tell us that whenever the high pressure fuel pump is replaced the camshaft and the follower should be checked for wear. The camshaft lobe pushes on the follower to operate the high pressure fuel pump. Frequent oil changes and use of synthetic oil may help with this wear issue.

    camshaft issue is what they are telling me after 4 times of bringing my car in for service for check engine light. now that my car is at 102k miles they will not cover under warranty eventhough I have documentation indicating problem was well before the 100k miles. issue started at 80k miles. best they say is that they will pay 50%. I think thats BS - anyone know who i can contact regarding this?

    Have been having loss of power and hesitation for over 3 years; had asked Audi to look at this numerous times and their response was that it wasn't a problem until the car was out of warranty.

    Replaced cam sensor at 103,000 when it was under an extended warranty, was told that the high pressure fuel pump, camshaft, cam follower assembly was functioning perfectly and in great shape; 3 weeks later the car had buckling, significant loss of power and hesitation and the High Pressure Fuel Pump had died. Was told again that this was not related to the cam follower wear, but they replaced the follower anyways. They refused to look at the camshaft. The check engine light is on again and the same symptoms are back...
