Sorry to start my first post as a cry for help but here goes! The car failed to start on Friday morning due to the battery to be u/s so I bought and fitted a replacement like for like battery (Exide Premium Battery 017 Amp Hours: (Ah): 100Ah Cold Cranking Amp: (CCA): 900CCA) and now the car throws up a whole host of fault messages (as below) and won't start, the engine turns over but won't run.
- Restraint system fault
- cruise control failure
- transmission fault! drive moderately.
- Start assist
- Fuel pump failure
- Drive control system
- reverse light right failure
- fuel pump
The restraint and reverse light faults were existing faults that were previously showing up but all the others are new. My son's father in law is a commercial auto electrician who he's helped out in the past (my son's a qualified mechanic but electrical) so he borrowed his OBD reader complete with BMW software and could extinguish some of the faults but it wouldn't connect to the ECU for some reason.
Any ideas on what to try or what's needed as I need the car as my everyday transport?
