Hi guys. I've watched this forum from afar for a while, and just bought a 2001 A3 last weekend thumbsup, so thought it's probably time to get involved. I love the car, and it's running fine...with 1 minor problem - the Engine Management Light is on. The previous owner explained that he took it into Audi as soon as it came on, but they could find a fault so just turned it off. It came back on about 4 months later and the same happened. I intend to get it hooked up to VAGCOM and try to diagnose the fault myself. I'm eagerly awaiting a Jabba Sports remap and wondered if I should sort out the EML problem before doing so? Also, what preparation should I take to get the best possible performance before and after the map? I was thinking : Spark plug change / clean; MAF clean (necessary?); Throttle body clean - can someone tell me what product to use to do this?; HT lead change; Panel air filter clean/change. Am I missing anything? Will this actually produce a better mapping process? Thanks!
