So I bought this audi a4 2007 that had a water leak from under the steering wheel and the rear doors wont open at all, when you lock and unlock the car you only hear the front doors «click».

I took out the comfort ccm and its conectors because it had big water damage. After the swap the interior lights started working and the trunk was also able to open, but both rear doors still dont work.

Fault codes : No connection to rear left / right door (J388, J389)

Im trying to strip the rear doors but it is impossible without it being open.

Anyone know what to check now or has had the same issue?
