My front headlamp indicator lights are going on and off erratically and I cannot figure out why. The car is pretty stock and nothing electrical has been done recently that should have caused an issue. I've never had a blinker light go out in the past on it. I thought at first the bulbs may be burnt out however the filaments were both good but I went ahead and replaced both of them since they were cheap from the dealership anyways. The bulbs are h21w. I've checked the fuses and they are all in good shape. Where should I go next? I have an OBDEleven. Would it help to post the codes here from that?
Now after this issue occurred I have replaced the stock radio with a RCD330 and have replaced the canbus for the steering wheel buttons to work with it so I know that is triggering a code.
I also have my winter wheels on without the TPS on them so those are the two issues to ignore.
