Hi! I came across with a problem not too long and looking for a fix for it. The problem is that I recently bought a tape light and from E bay and plugged it in my car's socket. Everything was working fine until I noticed that soon after I took out the tape light from the socket, a few things has stopped working. My car's interior lights wont turn on, all of the windows wont roll, sunroof wont work, and all the door locks wont work. Also the car keeps warning me that 3 of the doors are still open even when every door has been closed properly. I'm very worried about my car and I have the least experience with cars...Also I forgot to mention that I changed my interior dome lights with blue LED lights which worked perfect with no problems before I plugged in the tape lights. Please Help! Thanks A lot!

I own an Audi 2002 A6 Quattro 2.7t
