It began as an intermittent problem but with all of these symptoms occurring together :
seat-belt warning light on the dash;
indicators work on the outside but no tell-tale lights or audible clicker operating on the inside;
the instrument illumination comes on faintly after about a minute even though I've not switched the lights on;
the clock in the instruments and on the stereo display dashes rather than time.
Eventually it added the car only cranking 2 seconds after turning the key in the ignition.
The battery, although only 2 1/2 years old wasn't good (too many discharges from infrequent use?) so I got a new another new Yuasa battery from Halfords a couple of weeks ago. This has not solved the problem and even the delayed cranking still makes an appearance.
Suspecting the seat occupancy mat, I've had the seat out several weeks ago and cleaned the contacts. The problem went away briefly.
I've had the car to an auto electrician earlier in the week. Especially for him the car added non-functioning windows and wipers. He's diagnosed the Body Control Module, removed it to clean the contacts and then reset the codes. To be fair he wasn't confident the problem wouldn't re-occur, the next step probably being sending the BCM off for repair. The car was fine for a couple of days, but it's back to its old tricks.
From what I've read the symptoms, unless I'm much mistaken don't match the functions of the BCM. If you're still reading
does it sound like the BCM is the likely culprit?Thanks in Advance for any insight.
Thanks. I only have the most basic of generic scanners. I'll browse the options for BMW-specific scanners.
