In need of some help... I have a starting issue with my 07 S4. The car cranks strong but won't start. The TC, red battery, EPC, check engine(electrical), and ABS lights all come on. I had it in the shop, fault codes were no spark/ they "cleaned" coil pack connections and cleared the codes and the car started. Ran the car for about a month with several no starts. Let the car sit for a day and it would start. They also ruled out positioning sensors, fuel pump and changed the fuel pump relay... plugs are new. No rattle at start, car has 74k. Any help? Or similar issues?
