DIY: battery replacement & pinch sensor reset on E46/m3 convertible
So I changed the battery on my 2004 M3 convertible and my windows started acting funny, thought I'd write up my fix for others.
Problem : Battery died out. A 94R is the exact size for the convertible battery (its different on the coupe/sedan). After replacing the battery, the auto-up feature on both front windows stopped working and the master window switch would not put up the front passenger window.
The original instructions I found were as follows :
M3 Convertibles manufactured from 03/2003 and Convertibles from 09/2003 feature anti-pinch protection for the front windows. The owners manual "clearly" states that after the battery has been disconnected the pinch protection must be reinitialized.
-Keep key in position 1 or higher
- With convertible top in closed position, or hardtop in place, open the front windows fully.
- Disconnect and reconnect fuse 57 at the fuse panel. See 610 Electrical Component Locations.
- Close window by pulling up and holding window switch to second detent.
- When fully closed, keep switch in second detent position for at least 3 seconds.
- Repeat for opposite window.
This didn't work for me. Repeating 3-4 times, I only managed to reset one window at a time, alternating between which window I reset last.
What did work was this :
Reset both windows, use master switch to roll down all windows. In my case only the front windows went down and doubts set in, thinking I'd screwed that too. Roll up windows again, remove and reinsert key and you should be done.
Note: fuse needs to be pulled out individually for both windows. So, rolldown, pull & reinsert fuse, reset one window, pull & reinsert and reset second window.
