Loads of codes

[smdimjesus]

Just hooked up my new scanner, got a bunch of codes back.
2006 e53 3.0i

I'm trying to troubleshoot trans failsafe right now, also got a 4x4 dsc message the same time I entered limp mode.


08 DME: Signal, mass air flow sensor
0F DME: Plausibility, cutout time
2D DME: Multifunction steering wheel, monitoring, interface
44 DME: Activation, solenoid valve, tank ventilation
8B DME: Signal, CAN, tank fill level
8F DME: Tank-leak diagnosis with DMTL
A0 DME: Engine-throttle position controller, jammed briefly
A8 DME: Thermostat, map cooling, mechanical, jammed open
EA DME: Catalytic-converter efficiency, bank 2
EC DME: Trimming, oxygen sensor before catalytic converter, bank 2

91 EGS: CAN torque reduction
94 EGS: CAN engine temperature

04 LWS: Slider fault (calibration operation)
05 LWS: Internal fault (EEPROM)

5EBI DSC: Steering-angle sensor, supply
5F23 DSC: Engine management interface
5F42 DSC: Transmission control limp-home operation

54C6 VTG Oil Wear


Do any of these codes hint at what the cause might be? I've just erased the codes, but don't plan on driving until I can get a better idea of what might have caused this.

Also is there anything else I can do with a scanner to get more insight into what the issue might be?

Were they all current codes or just stored codes? What scanner are you using?

08 DME: Signal, mass air flow sensor
A0 DME: Engine-throttle position controller, jammed briefly
91 EGS: CAN torque reduction
94 EGS: CAN engine temperature
5F23 DSC: Engine management interface
5F42 DSC: Transmission control limp-home operation
The list above are probable causes. Since it's a first time scan, delete and drive. See how many come back. Report what comes back. Check at least the list above too.

Foxwell nt510, first time using the scanner, so I'm guessing stored.

Will do, how do I go about reading into the codes and finding out what causes them?

As a new user, go back and scan in OBDII mode. You'll get generic PXXX codes. The P codes will be helpful. The 08 and A0 should give P codes. Basically a dirty or faulty MAF sensor. It's a common problem on our E53. The MAF can cause all the others. Check the connection and use specific MAF cleaner. Worst case replace it.

actually with foxwell you want to scan with the BMW 'auto scan' to look into every module it takes about 8 to 10 minutes but will give you exact error codes for each model that has a fault.

[crystalworks]

Now that you've cleared, you'll have to drive for a bit to see what comes back using a full scan as Andrew suggests.

The thermostat stuck code could be the connector pins being slightly bent and not making solid connection. Myself and a few others have run across that. But also having the engine temp could mean it is in fact stuck open. Monitor your live coolant temp with your scanner or the cluster hidden menu to verify.

X5chemist gives good advice on your MAF codes.

Did that, what do I do with the results? Lots of faults

Just installed a new thermostat, I'll check out the coolant temp.
