Hi all,
I have a bit of a headache problem and it's my fault 100%. I didn't like that my car wasn't equipped with cupholders at the front seats so I've ordered cup holders for the central console under the armrest. When that cup holder came, I wanted to put it ASAP and needed to remove the phone from the arm rest and supposed to disconnect the wires behind the air vents but instead I've cut them with pliers while the car was still on (dumb I know). Next time I've turned on the car, I've got SOS fault. I've put my scanner through the OBD, and checked the codes using BimmerLink and Bimmer-Tool-Expert and these are the codes I'm getting:

Instrument cluster
1 error
A554: Alive phone

Gateway
1 error
E18D: Awakening device has 3 times unsuccessfully tried to wake up the network.
(Error_WakeUp_Failed).

Since then just the Bluetooth is not working everything else is working properly. I've welded the wires that I've cut-off from the phone, error is still there and Bluetooth is not working. I've ordered a new phone, no results, I've ordered a new Bluetooth module that is located on the left side in the trunk (boot, however) , no results. Now I'm about to disconnect the battery and leave it like that for couple of hrs to see if that will help, but in the meantime, I wanted to see if anyone had a similar problem. I'm assuming it's the CCC unit itself now.... Any toughts?

Have you checked for a blown fuse? That would be by far the most likely outcome from your ham-handed removal. ;-)

Yup, I've checked all the fueses, they are all fine 🥲

Hey guys, just a quick update, today I've double checked all the fuses all over again, just to make sure once again that is not them, and guess what... in the trunk at the position 80, 10A fuse has blown (on the scheme of the fuses it's not showing that it's for specific) , changed it right away, and guess what, problem solved

I don't know how I didn't notice that fuse the first time, but well, the important thing is that the problem is solved and now there is not a single error via diagnostics anymore

Btw. the other phone I bought for him has the same serial number but the hardware is 0.2 instead of the 0.3 that it used to be, and it still works.

Which method did you use to check the fuses, i.e. visual inspection, fuse checker, or multimeter?

in the glovebox i've checked them visually, but in the trunk they were hard to get out so I've checked them with multimeter
