I made a huge mistake by buying the Carista! After playing around with the coding of my E87, 1 Series 2007, both my high beam and side lights have stopped working all together. No dash error, nothing! I checked and there is no current going through to the lights. I believe it’s footwell module but not entirely sure. BMW service has been as usual useless. They checked the car 4 times already and they simply said we don not know what the problem is. After checking the OBD2 errors, i came up with the idea of just changing the footwell module and see what happens as I had the errors there (attached bellow) and as well as that I was getting desperate as my MOT is running out today. My car is currently at the service for change of footwell module which quoted as £720! Something scared me is that they said it’s not guarantee that it will be fixed. Now I am panicking. I was wondering if anyone knows what the issues might be? All the error codes appeared after I messed around with the codings.
