The cruise control has stopped working on my x-trail dci adventura. It comes on, but when you try to set a speed, it won't do it.
The engine light came on when the particulate light came on, but the particulates wouldn't clear, then the cruise control stopped working. Once the garage had sorted out the particulate problem, that light went off, but the engine light stayed on with the cruise control still not working. Can you please tell me why this would be and how to fix it (As cheaply as possible). Thank you.
