E36 M3. 182
Hi guys, I had a decat on my 182, and predictably had an engine light on the dash. The car ran fine and gave decent MPG, so I assumed that the decat was causing the light. I recently got a cat and a cat-back system fitted, and the light went out for the first drive or two. Then, when I got back in the car, the light came back on. The car still drives fine, so has the ECU stored the fault and flagged it back up?? Is it possible to get hold of a code reader to wipe the fault codes off?? Any advice would be great, cheers.
