Ahh thank you very much that makes sense,its an Automatic.
i have another X6 so i will swap over the mass air flow sensor and see if that makes a difference if not you say the lambda sensor next. i know about the MAS sensor but i dont know where the lambda sensor is,could you tell me where it is and is it easy to replace? thanks for the help  |
The lambda sensors are in the exhaust manifold. There are 2 lambda sensors, 1 for each cilinderbank. One is quite easy to find, between the radiator and the engine. The second (rear bank) is a bit more tricky.
Before replacing them I would try to measure them to see if you get a oscilating signal between 0 and 1 volt.
