Hi my 97 540i has developed a charging problem. I have searched the forums and tried various solutions but to no avail.
When I start the car everyhing looks good until about a minute of ideling then the no charge warning light starts flashing. The measurements on the batery are 12.3v to 12.4v. I have replaced the battery with a new one and have also gotten the altenator (air cooled one) tested, there was no problem with the test. I took the altenator out of the car to get it tested as I did not want to drive it like that (176km to test center).
I am thinking water has gotten in somewhere (serviced and washed the car prior to fault) or there is a loose connection somewhere?
I also drove the car (thinking water will evaporate) for 30kms, no charge light does go off at about 160km +/- 3000rpm.
I do also have a brake lining warning (waiting on parts) don't think that has anything to do with it though
Any sugestions welcome as I am at a loss. O and no I do not want to sell her as I still like the car alot
