Battery in backwards do I'm screwed?
Hi everyone, it happened to me in my 2009 528i 3 months ago, now the car is running fine but I'll tell you the story.
In May I lost my job an had an accident (with cheap insurance I couldn't get my car fixed from them.
It took a while to repair my car by myself but I did great, then my battery go fully drowned, and my buddy tried to jump the car from his tiny battery, I didn't realized he put the cables backwards during 30s
My alternator got worn, after I replaced it, the ABS, ASC and red Brake lights turned on, since then I couldn't get a reason why, I replaced fuses in good shape, abs module and wheel sensors, also the rear sensor got an alert, but now it was resetted and working well again.
I took the battery to another friend's house who put it to charge and now it works well.
I scanned my car and these were all the codes I got.
1.A0B4 CAS: Engine Start, Starter Operation History
2.A0B1 CAS: Input, Selector-Lever Position, Implausible History
1.CDBE Message (Setpoint Torque Request, 0xB Faulty, ReceiverDME, Transmitter DME-DDE/DSCCurrent
2.2A87 DME: Exhaust VANOS, Mechanism History
3.2A16 Fuel Tank Ventilation System And Purge Air System, Micro-Leak
4.2A82 DME: VANOS Intake History
1.CF34 Message From The DSC, Receiver EGS, Transmitter DSC Current
GWS (Gear Selector Switch) 1 problem exist
1.A83B GWS: Undervoltage History
ABS (Anti-Lock Braking System - DSC)
5DCF DSC: Control Unit, Undervoltage History
5F2F DSC: Interface, Transmission Control History
6DFB DSC: Control Unit: Pump Activation Current
6DC3 DSC: DSC Sensor: Adjustment Required Current
I Don't know if there's a burned relay or hidden fuse that it might cause the issue, I also thought to replace the DSC module under the passenger sit, if someone else have this problem before, I'll be very thankfully if you let me know what should be, thank you in advance!!!

No need if you've done it once. I just see undervoltage errors and if you've charged the battery and cleared the errors then you shouldn't be seeing that so something is still wrong. Need to look at your PDU under the hood to check fuses and relays and go from there. Everything seems to be a history or undervoltage which is wrong if you solved the battery issue

I'm also thinking put the old abs back again and reset, maybe the new one is not working well, do you know If only connecting the cable but no the brake lines should work? 🤔
It's so annoying to bleed all the brake fluid
