Battery disconnect and fault codes.
Posted: Thu Oct 04, 2018 6:15 pm
When examined car yesterday the car date and time had to be entered as the battery was disconnected and I could not check control messages in the Idrive.
Do you think this is normal. Would a dealer need to disconnect the battery or is it just to hide fault codes on the car.
Do Obd readers read codes that are deleted in this way?.
I used carly and read 16 faults which had not been cleared and then when cleared there was only one in relation to glow plugs and controller.
Please let me know if you have any advice as I’m plannning to buy the car tomorrow and hopefully don’t want to part with cash if I get a problematic car even though it’s under so called warranty.
