New to forums, so forgive me if i dont post this correctly.
ive got a 2023 (72 plate) B200d W247. the car is from the salvage, however it did start and drive. We had very heavy rain and water got through the broken windscreen and soaked the carpet on the passenger side where the fusebox and SAM are located. Ive checked the fuses and nothing was blown except 2 in the main fuse box under the bonnet that i replaced. The SAM didnt seem to get any water in it as the fusebox and SAM sit quite high on the b class like a van.
however since then the car wont start. ive got (parking brake see owners manual) and (ABS inoperative see owners manual) on the dash. The brake lights also wont turn off.

Ive had the car plugged in and these are the codes ive gotten back. any help would be appreciated.

C107D86, U012241, U012964

the temperature sensor and headlights arent plugged in (hence the codes for those)

If the SAM is dry, I would look under the carpet for CAN distributors where maybe the water did some damage.
Also, the Brake Lights Switch

ok thanks for your reply. ive look into that and report back.

moved to W246 forum since there isn't W247 forum...
