Kiwigunguy 0 Report post Posted February 1 I've got a bunch of fault codes on my E90 that I recently bought, and I need some help diagnosing what's wrong with it. Some of the codes are related to low voltage from the bad battery that was in it, so you can disregard those. The battery has been replaced. I'm mainly interested in clearing the check engine light and the DSC warning that keeps coming up on the centre screen. Here are the codes, divided into each vehicle system. Any assistance or advice you can offer is greatly appreciated. -Engine Control Module 2E81 Electrical coolant pump, speed deviation 2A2F Mixture control 2 2DEC Power management, battery monitoring CDAD Message error (request, wheel torque, drive train, BF) -EGS Transmission Control 51AD No message from Dynamic Stability Control CF2B No message from longitudinal dynamics management - LDM Longitudinal Dynamics Management 62CE Overvoltage fault - DSC Dynamic Stability Control 5DE2 Brake-pad wear: brake pads, front axle [Could this be causing my DSC warning message on the centre screen?] 5DF4 System voltage too low D373 No message (SZL C8, C9) D35B No message (LDM 213) 94BD Insignificant steering column switch cluster fault: Clear fault memory 5DF7 System voltage too high 5E43 Steering angle sensor: initialisation - JBE Junction Box Electronics A6CF AUC Sensor - MRS Multiple Restraint System 93D0 Undervoltage 9408 Undervoltage during self-test - INSTR Instrument Cluster A3B1 Message error (turn-signal indicator light cycle, 0x1F6), receiver instrument panel, transmitter footwell module - AMP Amplifier D6D0 Ring-break diagnosis has been carried out - FZD Function Centre, Roof A092 SHD initialisation A090 SHD mechanical system A670 Fogging sensor A088 Control switch SHD - CID Central Information Display A468 CID: Cable break to MASK or NAVI A46D CID: CID malfunction due to periphery - VM Video Module DBD0 Ring-break diagnosis has been carried out A38D Receiving system, aerial supply voltage: outside tolerance - CD-GW Control Display (Gateway) M-ASK-GW Gateway A179 Control-unit fault -FRM Footwell Module 9CC3 Mirror heating, driver's side, faulty [This has been fixed] 9CCE Battery exhausted - CDC CD Changer D810 No code descriptions - M-ASK-NAV Navigation System A3EC No wheel-speed signal - CCC-ASK Audio System Controller A199 Control-unit fault - IHKA Integrated Automatic Heating/Air Conditioning 9C4A Fresh-air/recirculated-air-flap motor 9C6C Supply, switch centre, centre console 12 V 9C50 Rear compartment stratification flap motor 9C4B Defrosting flap motor - CCC-GW Gateway A179 Control-unit fault Quote Share this post Link to post Share on other sites
Eagle 1662 Report post Posted February 1 Are the current faults the highlighted ones? Quote Share this post Link to post Share on other sites
Kiwigunguy 0 Report post Posted February 2 1 hour ago, Eagle said: Are the current faults the highlighted ones? No, ignore the highlighting. That was unintentional, from copy/pasting stuff. I'm just concerned with sorting the main issues of the CEL, DSC warning, and there's also something causing draw on the electrical system, because the battery will go dead if I don't keep it on a trickle charger. Anything else I'm not really worried about. Quote Share this post Link to post Share on other sites
Eagle 1662 Report post Posted February 2 Need to clear all codes, drive the car for a bit then rescan to see what comes back. A lot of those are probably from battery going flat. Replaced lots of alternators on E90's compared to the older stuff so probably pay to test that if you have a multimeter. Also need to code\register the new battery.
