    Blowing Coils

    Hi all, need some advice.Car is 2004 RS6. Was running rough during idle, took it in MAF wires fried, and 2 blown coils. 1 and 3. Repaired wires, replaced coils, got about 3 weeks of regular driving, maybe 2000km, and she is back at it. Code P0300, code P0301, code P0305. Also the air bag light is on in red. This also was the case when the car started to rough idle the first time. Is there a spike somewhere causing the coils to blow. Air bag related? Cant afford to be parked at the shop all the time need to find the source. Thank you for your input.

    I agree it may be a short. The car ran great for 3 weeks. Must be a loose wire to ground that is random. Question is how to find it without ripping the engine apart?
