Servus. Yesterday I was on a longer tour (about 300 km). Weather: Very sultry, as you know. Back in front of the garage set the turn signal, as suddenly the water temperature indicator flashed with the same clock. Box exhibited and the same again with switched on ignition tried: Same result. If I had then switched off the headlight, the light flashed once and then no more with. With turned on headlight then flash again, blink, blink etc. After an hour Wa Does anyone have an idea what that could be? At least not moisture on the plug connections, it had not rained. But the engine does not seem to have been overheated either, otherwise the warning light would have been on all the time. Thank you for your brain murmur. Greetings from Bikinger.
