I have a 2015 Audi Q7, bought on Friday with 19 miles on it. The next afternoon when driving as I continued to apply the gas pedal the Q7 lost power and the MPH went down to 0. When I take my foot off the gas pedal and press again it drives fine. It has done it everyday, only in the afternoon- spent time at dealer and it would not replicate in the morning. No codes on the diagnostics and no engine lights. Just loss of power while driving. Happens on a flat surface and incline all the same. Has happened on take off and also while cruising along. None at the dealer can figure this out. It has only 130 miles on it! And it is dangerous to go from driving at a speed and then engine goes down to 0mph at a random moment. Please advise!! Thank you
RepairPal Certified shops can diagnose and repair your 2014 Audi allroad. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
From what you are describing it seems like fuel starvation. This car has 2 fuel pumps, low pressure and high pressure. When you release gas pedal, fuel pressure builds up then car goes fine again. I've seen that before, but since your car is brand new, Audi will have to repair that for you. Good luck!
