BCU fault symptoms? Wipers on with engine off?!?!? etc etc!!!!
2 sets of symptoms for you on my 2006 ('56 plate) Mini Cooper R50. Car done 70000miles.
NB Both these have happened after wet weather:
1: Couple of weeks ago:
Car would not unlock off the remote key. Had to manually unlock the car. Got in the car, it wouldn't start. When i took turned the ignition off, the ignition lights would stay on (basically more or less every light on the dash, as you'd get when turning the ignition on to start the car).
Also noticed the brake lights were on permanently!
Tried starting the car a few times to no avail.
A few minutes later, tried again. Car started. Success. Brake lights were off.
But, when i turned the key back to the off position, the car kept running. It kept running even when I took the key out.
Left car engine running, heater on hot, blowing to the floor position (suspecting dampness around the BCU).
This sorted the problem until today.
2: Today, drove as normal to work. But heavy rain and some big puddles on the road. Switched off at work, locked car as normal. Two hours later the porter told me that my wipers were on. Went to the car, the wipers were indeed 'on'. Started the car to make sure the battery wasn't draining too much. Started fine. Wipers went off (Wiper switches were in off position anyway).
Switched off the car, the bloody wipers start up again. Only way to stop this was to take out 2 fuses in the front passenger compartment, one 5A and one 20A. This stopped the wipers. Fuses back in
Drove home, Car as normal.
Took off the inner sill trim panel, BCU seems dry as a bone?
My OBD2 scanner shows no faults.
Local garage reckons it's the BCU and has experience of Minis...
