Before that, I wanted to pay my mother a visit, go, and the engine control light goes on. Restart (i.e. by battery), but it is still on. To my mother (5km), temperature goes up, until 3 o’clock. Then she suddenly starts to drive a lift (i.e., down, down, half-high, up, run…. (i.e. up until 3 o’clock, not 12 o’clock). Same game on the way back. Plug down from the thermostat sensor, WD 40 in, try again. The sensor is only half a year old. Sounds to me, and feels like it’s already broken again. Must be picked up by the mechanic, error tomorrow. Does anyone have any idea what it might be? And the best thing to do is to go to Norderney on holiday with my family on Friday. I installed the roof box yesterday, and it was clean again. It’s about 800 km from me. It always happens when it doesn’t fit in. MIST! Mike
