If you can be a bit more specific, on what the problem is/was we might be able to help, i take it you have played with the POD, by pressing the main brass lights button and fog light switch?
Fault code I you mean? I had that code yesterday, looked at sensor and a wire had broke, soldered it back and the fault code went, no reset needed. Have you used the software and seen if the ecu is getting a temp signal and its just the dash one gone?
