BMW Repair Questions? Ask a Mechanic for Answers ASAP
Hi. I have a 2003 BMW Z4 E85 3.0i. 2 days ago, after disconnecting the battery and fitting a new slip ring, the aircon, electric roof, indicator light in the cabin, central locking from the keyfob all failed, also the airbag light came on. It appears no power is getting to them although the car starts and runs perfectly. Tried again several times yesterday, after checking every fuse was Ok, but still nothing worked. Then, after 10 mins I tried again and the hood suddenly worked for 3 up and down cycles(but the windows did not come partially down) after the third cycle the hood stayed down and would not respond again. The red light comes on when pushing the button but no sound. I have checked the tightness of the negative lead from the battery to the bodywork/chassis in the boot(trunk). Any ideas?.
Hi. Thanks for that, it did seem to be some kind of shutdown as the roof has worked again for 2 operations and then stopped working again. Also the BMW factory sat nav screen has swung open at the push of the button a couple of times and then shut back down again. It is now refusing to open again. I have booked the car in with a BMW specialist on Monday. Thanks again, I appreciate an honest answer and will score the highest rating
