“My 2014 Audi S4 has a epc light that keeps turning on while driving that car. The epc light will put the car into limp mode and will have a rough idle and can barley drive. When that light turns on you have to pull over immediately and restart the car to continue driving and is a complete safety hazard because it will happen when you are on the freeway. The light mainly turns on when you are trying to get up to speeds of the flow of traffic. I have taken it to the dealer many times to get this issue resolved and they keep saying there is no issue with the car what's so ever. …”

Research indicates a faulty mechatronics unit, but 2 ny dealerships continue to state no issue.”

The repair required additional valves and hoses he added to the low pressure fuel system to compensate for the poor vapor management design. The car had to be towed to a dealership where the appropriate fix and TSB was executed. …”
