Hello, I have a problem with a BMW 320 td compact Serie3 150 cv . When you put the contact traction control lights turn on and the temperature is raised to maximum. the engine around but dont start to work and we cant use diagnostic machine to find a problem. we have observed this problem is more frequent if the doors are open And we believe that is the ecu. we believe we can probably repair it but we dont know how, and, if we cant repair the ecu, can we put another ecu and kill the immo ?? How can kill the immo?
this is the ecu204361
Thanks for yours attention and sorry for my english.
