Hi
Just had the 4 coil packs changed on my 1.8T and that has helped fix the mis-firing / rough idling problems, but I've now noticed that when driving and the stereo is on, when ever I accelerate there is a buzzing which comes though the speakers. It gets quicker and louder the harder i accelerate. It doesn't happen when the stereo is off. Any ideas?? This didn't happen until these were changed, the guy also tapped up the slightly cracked wires connecting to the coilpacks...
Any info or comments would be much appreciated
Cheers
Jonny
