W211 e320 cdi ABS ESP BAS Fault
A couple of times the car hase had the ABS ESP & BAS lights come on and for a few seconds the car looses power shows these 3 malfunctions and then carries on as normal.
Once the car had all these faults come up and it died and would not restart. After recovering it back to the garage I bought it from they thought that the fault was with a faulty alternator so replaced it.
I have checked the aux battery & that is OK, the main battery is OK but not fully charged. You can hear the brake pump going whilst driving but as I have not driven many of these models I am not sure if this is normal.
But the fault still persists, I will be taking it back again but has anyone got any idea's on what could be causing this fault.
