I call upon the collective wisdom. I have a 2002 P38 66k until now recently working ok. I have searched and searched on this one, but no one gives a conclusion to their problem.
Recently and intermittently car has cut out while driving, followed by gearbox fault, ABS fault Fuse 6, 7 and 17 failed. The car has re-start with no faults after a few moments. I have Hawkeye – no faults stored on EMS, TMS or ABS. a slight whir has been detected from the engine bay, I thought this was cooling fan/s on way out.
The battery has been a bit iffy for a while. So have been bench charging – off the car.
Now the car is turning on with faults and now won’t start (just cranks). Last time it started, battery 12.5v and Alternator giving out 14.4/5 at 2k rpm – then just packed in on the spot.
Changed battery as old one was shot. There seems to be an instant drain. Getting 12.08v on the three BECM feeds on the engine bay under fuse box feeds. When taken off the car the batter springs back up to 12.5v.
Wires under the engine fuse box (3yrs old) seems ok, as does the BECM (reconditioned 5yrs ago feeds under the seat.)
Could the noise be the alternator packing in? could the alternator cause the voltage drain and cause these fault codes and lack of power to the BECM?
Is it the dreaded BECM relay 15?
Any help gratefully received.
