I read that they are all on the BSD line or that it might be a water pump failing. Just wondering if anyone else has had something like this before. Alternator was replaced by previous owner about 10,000 miles ago. After all of the data bits are transferred, a synchronization period follows. 2E7C Bit Serial data interface 2E8E IBS Communications Extra info: My water pump seems to be running continuously while the car is off. (an original bosch is in the aftermarket about 220quid, the bmw price. SSI was developed as a serial interface technique for use with absolute.

If you're not comfortable with dismanteling an alternator (the rectifier is at the back, you dont have to open the complete alternator) you have to buy a new one. I think you can get the rectifier/voltage regulator as a separate unit (it bolts from the alternator).įrom bmw its (obviously) pretty expensive (about 120 quid), but in the aftermarket for about 30 quid.īMW partnumber for the voltage regulator is 12317515319 Have you measured the battery voltage with the car running? How much was that? You can check if thats still connected or damaged. The bsd wire is the connector that goes into the alternator (so not the big red wire but the smaller black connector).

My obvious worry is driviing to get it fixed/diagnosed and breaking down on the way Thank you, so if i replaced the alternator ? can you fix a rectifier ? the alternator IS charging i know, who could find/change the bsd wire ?
