3-Series (E21, E30)Chat relating to the BMW 3-Series from 1975-1983 and 1984-1991 line. Specific models: BMW 315, BMW 316, BMW 318, BMW 318i, BMW 320/4, BMW 320i, BMW 320/6, BMW 323i, BMW 320i. E30 Family models include: BMW 325e, BMW 325i, BMW 325is, BMW 325ix.
The reverse lights on my bmw 320i auto e30 are playing up. There seems to be a loose connection. When the car is in the reverse position and i push the gear lever forward slightly the reverse lights come on and when i push the gear lever back slightly they turn of. So if you just simply put the car in reverse sometimes the reverse lights are on sometimes they arnt. Any ideas?
My old e30 had a similar problem. The switch is a PAIN to get to...I would recommend trying some other things first.
The thing that FIXED it for me was the connector under the shift boot. The wire for the reverse lights goes through that rubber shift boot (under the leather boot) and down into the tranny. Right before it goes through the shift boot there's a connector...I would guess this connector is loose (or maybe there is a short somewhere close to here) that may be why when you have the shifter in certain positions that they work.
I just disconnected it and hooked it back up. They've worked perfectly ever since.
Give that a whirl and see if it helps...if nothing else, it'll only take you 10 minutes and it's one less thing to troubleshoot.
thanks for your help. On closer inspection realised when in park the shift rod didnt slot into the park gap on the shift gate. Adjusted the gear shift rod and lever so the actual gearshift was forward more. Now when in reverse my gearshift sits forward enough to make contact with the reverse light switch. So it was nothing to do with the switch just the position of the shift rod.
