I have a problem which my dealer has not been able to fix. Its starts with fluctuations of the temperature gauge - 90 down to minimum. The the steering connector warning comes on, then hill holder, then ESC. The engine management light comes on and "check engine" message. If the car is stopped the ESC light goes off but the management light remains on. If the car is re-started a few times eventually the light goes off. Sometimes there is repeated clicking behind the control panel and it seems related to the temp gauge fluctuations. Any ideas anyone?
