x5 e70 rain problem
 

x5 e70 when it rains i cant drive it it throws on check engine, transmission and electrical problems. where do i start looking?

buy a code reader.

have the inpa but there are more than 30 problems during the rain. once it dries no lights its back to normal. trunk is dry so im guessing its not back there.

There are drains in the front engine compartment in front of the fire wall that holds the DME. The drains can get clogged w debris.


There was a recent post here or on BF about this, with pictures...
