I have recently purchased a a4 1997 model 1.8 non turbo, I had an after market alarm on the car when I purchased it, I drove to work and the car was running rough, it would idle it just cut out, I set the alarm and when I came to unlock the ccar would not unset and the alarm just went off, got the car towed home and removed the alarm, the car won't start and the starter does not turn over on the relay board positions 3 and 4 have nothing in them, any ideas would be most welcome
