Hey guys so I have a 2010 E93 335 and it got water in the headlight somehow from pressure washing the car. I swapped the headlight control module which had water in it to no avail. However that headlight getting wet has caused weird electrical issues. It rained for a week straight and I didn’t drive the car any, jump started it. Ran it for awhile but then when it cleared up I went to put the top down and the KOMBI went black. Now car has correct voltage at OBD via Easyconnect but ISTA will not connect with the car. I have checked all fuses which are fine, some windows work, roof does not work, KOMBI not working, and car when sitting keeps sounding like it’s wanting to cut itself on or switching power.

These are persistent codes:
2DC3 - DME: Monitoring, terminal 15.
CD94 - Message error (ambient temperature/ relative time, Ox310), DME receiver, KOMBI transmitter.
CDAO - Message error (terminal status, Ox130), DME receiver, CAS transmitter.
CDA8 - Message (status, KOMBI, Ox1B4) incorrect, receiver DME, transmitter KOMBI.

I can also unplug 30g relay or when CAS is partially plugged in KOMBI will work. Car starts just fine every single time.

I’ve checked voltage at the CAS pins on the 41 pin


Pin 18

• 11.6 v

Pin 19

• 11.6 v

Pin 8

• 12.26

Pin 13

• 12.26 v

18 and 19 are terminal 15wup so is this steering towards a wire messed up or the CAS? I have ordered a CAS to at least try.
