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.

Fuel Pump, Fuel Filter replaced at 85,000 then at 100,000 went out again.
Replaced under warranty by Audi. The dealer told me this is a known problem and Audi has extended the warranty on this part for 110,000 miles.
Exactly as described. Check engine light and hesitation. Replacing cap and since there is wear on the camshaft, a part of that plus doing the timing chain and water pump now (instead of waiting another 25,000 miles). Painfully expensive ($4000)
I recently purchased my Audi A4 as a second vehicle when it had very low miles (27k) for its year (2007). After a year of using, adding only 5K, I took it to the dealership for it's first oil change and got a general vehicle report of excellent condition from the Audi dealership. Just days after the oil change, the engine light came on and I took it back to the dealership to ran a diagnostic test and they indicated the fuel pump by the gas tank was showing figures in excess of the norm, whereas the other fuel pump by the engine was normal. They recommended changing the entire fuel pump system and quoted me a figure over $1,000.00. I called Mercedes dealership to see if I could get a second opinion and they indicated they don't look at Audi's, when I purchased it from them. Very frustrated with both dealerships. Looking for an alternative solution. Any advise would be most welcomed!
