Hey guys as we all know I have a msport 335i. I have had most major things replaced. Well I have another problem again. I'm not sure what it is now BMW have replaced the Ecu with a new one. The car with the old Ecu wasn't unlocking or anything the car would be dead. Well that's the problem with it now after we have replaced the Ecu with another one. What I think the problem is are the wires because they get very hot. We have noticed that the car gets stuck when it is a h to day. Please reply if you think you noe what the problem is. This is urgent please reply.
