R55 BimmerLink error codes. more detail

Well, BimmerLink is kind of like watching the movie, “The Ring” I’ve got all these error codes that haven’t yet thrown a CEL, but they could happen.

Could someone help me to understand a few of them?

2F07: DFES_DTCM.DFC_THMNPL_C - MAP THERMOSTAT, MECHANICS

so if my car isn’t running hot enough does this error point more to the water pump or thermostat?

Car Access System
2 errors
A0B8: HALLSENSOR_RAST_KS D904: K_CAN_LEITUNGSFEHLER

Sliding/Tilting Sunroof
1 error
DA04: ERROR K_CAN_LOW

I’m going to the dealer next week to hopefully get a new FRM replaced under warranty. Hoping maybe it will clear out this exterior light error. All my exterior lights work. What the hell is a “limiting light”?

I also get this low beam error but all my headlights work and I don’t have fog lights. The running light works but when I got the car about 2 months ago I fixed an error for the left side by replacing the left rear light assembly.

Driver's Side Footwell Module
3 errors
A8AC: LIMITING LIGHT LEFT DEFECTIVE A8C1: REAR RUNNING LIGHT LEFT DEFECTIVE
A8AF: FOG LIGHT RIGHT, E90 M3: DAYTIME RUNNING LIGHT RIGHT DEFECTIVE, PL3 FROM 07/14 AND (SA5A1 OR SA896): BRAKE LIGHT RIGHT DEFECTIVE

Gas gauge seems to work and my sunroof opens closes.

Sliding/Tilting Sunroof

DA04: ERROR K_CAN_LOW

Instrument Cluster

9319: ERROR SIGNAL TANK RAW_DATA_FILLING_LEVEL_LEFT

Is my stereo going to die?

Amplifier
1 error
D6C4: BUS WIRING INVALID


If Bimmerlink shows these errors but when you click on the details and it says it’s not generating a code does that mean they’re about to fail but just haven’t yet? Again this damn app is like watching “The Ring” movie.

I love this car, but mostly while it’s standing still...

Thanks

 

some codes pop up as a consequence of another thing. for example, if the FRM is dying, it will surely effect other modules through the Can or K bus. Similarly, when the battery starts to flat out, multiple codes pop. Since you have a sunroof, check the fuse box on the right side for water leaks and such. clear the codes and see what pops back up.
