(I have a 2003 audi a4 1.8T)today my check engine light came on after driving at a speed of 65mph. I took it to the dealer and they told me that coil #4 has failed as well. They have already replaced my entire engine harness and stated that was the cause of my previous coils failing (coil #s 1,2, and 3). I have only had the car since april 30, 2007 and since then it was necessary for me to replace my engine harness, coil numbers 1, 2, & 3, some seals, some hoses, and a fuel pump. I bought an audi for the quality and reliable but it sounds like ill be going to bmw or mercedes from now on. *Tr

Lyon investigations, inc. After inspecting the primary drive assembly on a 2003 ultra chopper it has come to my attention that the nut securing the front sprocket spacer is not torqued sufficently to keep the rotor and its washer from moving. This movement eventuially causes the splines to wear in the rotor and spacer prematurely. This can cause the engine to stop running when the splines in teh rotor strip completely.*Ak
