2002 SL500 with multiple lights on dash

[eminem94]

Hello, I was hoping someone can help me find out what's wrong and what reapirs I need to carry out to get my SL500 up and running normally again.

The car turns on and drives fine, there's no bad sounds from the engine etc when driving the brakes stop working and i have to essentially hit the brakes 3-4 times to come to an abrupt stop (i only drive it slow on private land because of this)

The lights on the dash are SRS, ABS, ESP, check engine light and low coolant level.

The previous owner for some reason had a BMW battery in the back and so i changed that to a new Lion 096 AMG 70ah 760cc battery and it took away some fault codes but still some are remaining. The roof also doesn't open/close fully.

Fault codes are:

Engine: P0151 / P0131 / P1999 / P0561 / P0101
ESP: C14BT (steering angle sensor not initialized) / C14F8 (overvoltage supply)
Braking system: C24F8 (overvoltage AT terminal 87)
Roof module: B1166 + B1167 = power steer oil level too low

Could someone please help me figure this out? I am able to carry out some repairs myself but if it needs a lot of engine work then i'd have to take it to a mechanic

Appreciate the help in advance!

Thanks

Have you noted all codes then deleted to see what returns
Roof oil level lo seems self explanatory?

yea i've cleared the codes, then drove it around for 5-10 min and then check the codes again and those were the ones that showed up

If the car runs smoothly with no apparent issues then my thoughts would maybe be damage to the wiring loom somewhere? I am pretty sure this could be the reason the brake control (SBC) might be playing up. Is the car water damaged at all?

No water damage from what i can tell. Any idea the first place to start looking for a fault? I want to try repairing it myself if it's minly wiring if it gets too complicted will just give it to an auto electrician or sell it for spare/repair

General water damage spots would be in the boot or passenger/driver footwells. Sorry I am not much more help

Check under passenger footwell - lots of electrics - also under boot floor - R230’s can leak (a lot) and the electrics suffer
