I have been back and forth to the dealer to try and fix my check engine light - always 1 day after they turn it out, it comes back on. On the last trip they found a cable to a fuel injector was kinked, and not making a clean contact, and also upgraded the software - but the light still comes on 1 day later. 4 trips and counting.

I have searched the site for previous posts regarding this, the main appears to be related to the fuel cap, I followed these suggestions to no avail. I would be interested in any suggestions? I can then take these to the dealer.

Many thanks,
Matt
