Warning lights
 

Hi guys an gals
Ok so I have a 2005 m5

The issue is I'm getting a few warning lights come, like high voltage battery drain, pdc failure, traction control failure, fuel pressure low, injector pressure low, but I have a code reader and when plugged in they are either not stored or once deleted they don't return and another might pop up a few days later, iv been told there might be a software problem and there could be an update, anyone had a similar issue, the car always runs spot on all the time.
Thanks Gareth

Sounds like your battery is going to die on you any day... I'd swap the battery and the problems will probably go away. Just do a search, all those errors come up with low battery voltage.

Hi Iv not long had a battery on it but one fault that's common is the high rate battery discharge ???

No, all those faults are common.. high battery discharge is just the #1 saying your battery is dying.
