Ok so my car lost some functions after I installed some silver guage rings a week or so ago. First off, I can't cycle the temp./MPG/MPH settings, I just get get the time. Secondly, my right side mirror no longer adjusts when backing. Also the washer fluid light is on now. So I took it to a local BMW mechanic and he blames all the malfunctions on my headlights. I have P46's installed and they've been in for a month now. There were no problems at all after I installed them and these problems all came after unplugging the guage cluster then plugging it back in. The mechanic wants me to drop the car off with him so he can test the entire system down to every wire. Not gonna happen since the car will be shipped in the next week or two. Any ideas?
