This means if you see an "11", it could be TheĮxtra "numbers" in hex are A,B,C,D,E and F. Hex format is a hexadecimal number, used by computers to count in base 16, so there are 16 numbers before "10", instead of our ten. The code reader or diagnostic tool will ask the module for any stored codes, and it will receive a number in hex format. This is because many fault code tables, like our OBD code listĪre showing the OBD2 generic codes. You don't recognise, or one that doesn't appear in a search. Don't know, I'm doing the research.īecause I knew regulator was keeping voltage above 15V, so I decided to do that to preserve the battery.If you are reading codes from specific BMW modules, you may find you get a code That way, I may have caused some damage to the alternator excitation module inside. I think that I may have caused the problem to get worse, by disconnecting the battery cable from the alternator and keeping the other little wire connected. Yes, I know your story found it on the search. I replaced just the regulator and it didn't fix the issue.Įdit: as a matter of fact take a look at the link posted above that's actually the thread I told my story in lol Like said above, everyone said replace the whole unit but I didn't listen. This caused the alternator to work intermittently until the crack got worse then the alternator stopped working completely. For me, the bearing for the rotor cracked. As these cars age the alternators have a higher chance of failure.
So your battery drained while the engine was running? This sounds like a classic faulty alternator. Every startup is that way.Īlso, PDC's not working, Cornering Lights, and Bluetooth Telephone too, but I can live without them.ģ6 TEL/MULF ERROR_ECU_SUBFUNCTION_NOT_SUPPORTED_INVALID_FORMA TĪDR Gen. When revved to 2k RPM, warning is gone, alternator voltage turns 14.5V until engine's off. Had a battery drain with engine running, with no warnings on the dash.Īfter full charging via tender, alternator was sometimes off (battery voltage only), sometimes above 15.0V.Ĭhanged the voltage regulator, and battery charging fault warning throw right on engine startup. Also fuel gauge is oscillating on turns and acceleration/braking situations. Hi guys, my car's got these fault codes on, I don't know what to do, I may take it to an indy shop, but would rather do things myself.Ĭar's got ABS light on, DSC light on, EDC light on, Air bag light on (system restraint).
