I was on my way to work and got an engine malfuntion warning. Plugged in the OBDII Scanner and this is what i'm looking at. (see attached)

***EDIT*** I tried starting the car again 5 hours later and it turns on with the same problem but now it's bouncing re revs on its own from idle to 1500rpm. Any Ideas?

Engine Codes
2F6C - Exhaust fumeflap, input signal
29F4 - Catalytic Converter Conversion
29F5 - Catalytic Converter conversion 2
2DC3 - Control Klemme 15
2E8D - Intelligent battery sensor, signal transmission
2D20 - Accelerator pedal module, pedal sensor, plausibility between signal 1 and signal 2

Footwell Module Codes
9CB3 - Front level sensor defective
9CB4 - Rear Level sensor defective
9CBA - Short Circuit 3
9CC3 - Mirror heating driver side defective
9CD4 - Communication with belt conveyor driver side defective
9CD5 - Communication with belt conveyor passenger side defective
A8C3 - no description

Instrument Cluster Code

Things you may need to know:
2010 N54 e92 xdrive manual 85000kms
bone stock other than DCI
Replaced in the last 8 months:

• coils
• spark plugs
• Index 12 injectors
• OFHG + oil cooler gasket
• walnut blast

I'm thinking this might be battery related.
-5 celcius/23 F ambient temp at the time
we've had a stretch of -15C/5F over the last couple of days
i have no idea when the battery was last changed. I attached a picture if you guys might know how to read the battery production date.
i bought the car april 2019

Thanks in advance for your help!

I would look into the battery also. It looks like battery indicator is yellow (replace battery).

I can't tell the date but it's stamped on the top of negative thermal post. The code is a letter and a number. The month will be a letter, "A" represents January, "B" represents February and so on. The year will be the number, "8" would be 2008.

Hey thanks for the reply! i did some more digging and i found out the battery was made june 2011. i think it might be that LOL

Yeah batteries do weird things. It seems right for end of life span.

[Nick54]

so i replaced the battery and it got rid of a bunch of the codes. I cleared everything and a 2D20 code wont go away now. Any ideas?

Try using INPA or MHD to reset the adaptations for the throttle.

Bad battery will make the cars go nuts.
You get "Vegas" mode on the dash and error codes galore.

Large number of unrelated codes is often caused by a weak battery.

I gave you this advice on your last post but continuity check every wire that goes from the pedal and check the grounds I gave you a couple links to people with same solution. Start there. Don't do anything without new battery first

thanks for all the help everyone! seems that it was the original battery on a 2010.. I could only imagine what other maintenance has been avoided on this car.. and the 2D20 will be resolved with a new pedal
