Hello colleagues, I had a strange experience this afternoon on my way back to the office… Suddenly the tacho needle fell to zero, the gear indicator was gone and the green lamp for the 6th gear went out. I had the same thing a while ago. After a minute or two the tacho worked again. That was the same last time. Normally I would think Tacho has a Macke or a Wackler, check contacts and so… But there was something else: The engine has at the same time also It was normal, as long as I was on the gas, but when I switched down and turned off he threatened to go out. No stationary gas, so to speak. I had to keep the box alive with the gas grip. And then it went out immediately on the company parking lot, too, when I let go of the handle. Not slowly coughingly died, but gas off – paff – out. But the tacho had worked long ago again. Ignition off, again on, tried to start – and it chuckled in idle before itself as if ni So I hope I’m still coming home and I’m not stranded here in the office… Does anyone have a flash of mind what that might have been?
