Having acceleration problems. Varies not consistent. When applying pedal to accelerate. The car doesn't respond. RPM drops to zero. Engine still runs but no movement. Releasing pedal and trying again works intermittently. Scary when trying to get car out of danger.

I have gone gone to the dealer numerous times visits right after I had the scheduled oil changes done. The oil light / consumption issue happens after I've gotten an oil change, but 7,000 miles before the next one is due. I get afraid thinking that my car is out of oil. I do not have any oil leaks. Oil is leaking around ladder frame. This has been a know issue for a few years that I have been having and Audi will not resolve.

Fuel is leaking from the fuel pump flange and producing a strong gas smell in the car. The issue is very similar to nthsa campaign 16V660.

Upon having 3 consecutive oil changes, my car suddenly began to burn oil (no leaks) after the first oil change upon driving less than 900 miles. Then the second oil change did the same thing upon driving under 300 miles. It actually ran out of oil totally. I added oil as instructed by the car, and it burn the oil withing 250 miles of driving. I took it to the dealer, who acknowledge that this model and year had the wrong engine put in the vehicle. They would need to replace the entire engine at my cost, with possible reimbursement to me. Not acceptable, since they acknowledged the defect. Oil continues to burn at a very high rate and potential cause additional engine problems while driving.
