i got an error code 005DEC with no lights on the dash. the code states power reduction. anyone knows the reason behind this code? my car is a 328i e93 2012 rwd. need help urgently to stop this code.

Hi!
I have the same code regularly, really hard to search in google because it gives many "5 December" results, I never knew what it was, and INPA doesn't say it is brake related.

Could it be something related with the abs/dsc sensor? Or the wheel bearing (as it is part of the abs/dsc system)?

[rami.zein]

i think it might be a wheel speed sensor as i can see from the carly report... did you change the wheel speed sensor and still get the code?

[N53]

I didn't touch anything yet.
I'm about to change the rear wheels bearings first, the car has already 150k km's, I'll see if the code is back after that. If it does, the next thing will be the sensor of the rear left.

i suggest doing the left rear speed sensor first... its less costly and might end the problem... anyways please keep me updated as this problem is hunting me 😭

so i figured something out... once i hit a specific speed this code appears.. i think it's around 100 miles or so...

I don't know how many miles (or km's) it takes to appear, I only know it doesn't appear every time I read the codes.

I'm almost receiving the new ATE sensor, maybe today.

I just checked two of the errors I had some time ago (I didn't remember that I kept photos of it until today), they were both at 99km/h.

I don't know how it could help us to understand what exactly the problem is, but I'm installing the new sensor tonight, I hope it solves the problem.

@N53 Any new updates regarding codes 005DEC and did you install the wheel speed sensor?

Obviously, you just need to maintain 100+mph.

But seriouly, seems to be a sensor related issue whether it is hardware or software. Just for shits and giggles does playing with DSC have any effect? Does a long press disable eliminate the code?

And another shits and giggles thing to try is resetting the tire pressure warning(if you have the pressure based system)?

Not sure what it will tell you, but it does narrow the troubleshooting.

Yes, I did install the wheel speed sensor, erased the codes and drove for +/-2000 km's, there are no codes so far.
