Hi everyone!
So,
My car is 2009 E90 335i msport lci model
The car working absolutely fine but, when i turn off the car and take off the key after 1 minute the water pump start working on full power until the battery totaly drain, sometimes stops when i open or unlock the door but after this if i dont put the key to the ingnition the pump start works again!!
My car has no skyblue dme relay in the engine compartment fuse box so not that is the problem, water pump working i tested already and also when the car running works fine, temperature sensor i think working as well because when i open the hidden menu can see normal temperature and when its chanching...
So please if anybody can help its could be really great!!!
I hope some of you can!
Thanks

Have you scanned the codes? How many miles? What was the last mod or maintenance done on the car?
