HI All
I have an issue with the DIS where it randomly switches its self off for no apparent reason. It can be off for months, and then randomly switch on again. This week I was sat in queue, operated the electric windows, and the display went off. When it's on it functions perfectly, no display issues or any other problem. When it's off, it also takes out the steering wheel mounted telephone controls.
I have tried to switch on again via the bottom mounted RH stalk switch but this doesn't switch it back on or get any response.
It looks like a power line fault, but I haven't a clue where to start fault finding. I'm not an auto electrician, but an engineer with a mix of skills. Has anyone seen something similar or can someone point me at a sensible place to start. The wiring diagram's I've found so far haven't been particularly helpful either
Thanks in advance
