Fuel cut-off/surging when accelerating and tapping noise from engine. Engine is throwing engine codes; a loss of power is present when accelerating. This occurs every time I try to accelerate. This is a known issue with the cam follower and high pressure fuel pump on all 2. 0t fsi motors from vw. My cam follower has a hole in it (have the part) and the high pressure fuel pump is worn down (have the part) because it has made contact with the cam lobe, which has been scarred (have the part). Replacement requires a new cam, high pressure fuel pump, and cam follower. The design however will require constant inspection of the cam follower to avoid major engine failure. All 2. 0 t fsi engines will experience this problem. Volkswagen has a TSB #2015153 dated December 16, 2009 that warns of this problem upon cel light being shown. But by then the damage was done, upon further inspection it had a hole in the cam follower, with severe damage to the cam and high pressure fuel pump. Repair cost was over $2,000. 00. After researching this I found out this is a common problem with this particular motor. So much so that voa extended the warranty to ten years and 100,000 miles just for this exact problem. Unfortunately they used VIN numbers and my VIN numbers is after the cutoff point even though it's the exact same motor with the exact same problem as the earlier VIN numbered cars. They need to cover the affected motor numbers not the VIN numbers.
