This is very know problem with vw/Audi 2. 0t engines that I was not aware of before it happened to me. Basically camshaft follower broke causing damage to high pressure fuel pump and camshaft. The cam shaft follower is too weak and it brakes too often for some other people. There is ton of complains on the internet about tjis spevific problem. Now the high pressure fuel pump is on back order since July and no one knows when it will be available. I'm stock without a car and no one can help or even tell me when the part will be available. Audi is not doing anything to help. I don't know what else I can do. Please help!.
The vehicle started to stall and was not responsive to acceleration. It dangerously lost almost all of its power in the middle of the road. The next day it failed to start. The problem is a very common problem that Audi has published in their service bulletin 15 07 02 for replacement of intake camshaft and high pressure fuel pump follower. Audi is aware of this issue and should be held responsible for this defect in manufacturing and workmanship. Failed components: 1) intake camshaft 2) follower and high pressure fuel pump.
High pressure fuel pump defective. Car will not move when gas pedal is applied. Vehicle also does not accelerate at times when merging with traffic because of lack of combustion in engine. Have had close calls when crossing lanes of traffic because of this. Many times there is a 2-3 second delay before acceleration occurs.
When weather heat conditions are above 90f the car's fuel pump will sporadically glitch/shut -off and prevent fuel to be transferred from the tank to the engine for combustion. This makes the car stall momentarily when accelerating from a start point and while driving. I took the car to Audi service center, and they verified and confirmed the problem and said that the fuel pump needs to be replace with a superceeding pump. Audi service center stated that this problem has occurred in the 2006-2008 A3, and a4 vehicles. My car has 66,000 miles and has gone past the warranty limits for a no-charge replacement. This fault condition is a potential hazard for drivers.
