Topic: Possible bug?
I have my S5 screen gauges set to EGT, supercharger revs and boost. Yesterday whilst driving I noticed that the supercharger revs needle was at zero, and even with the clutch open it is always at least about 200rpm which is noticeable. I cannot be 100% sure that the other two needles weren't also at zero but I think I would have noticed if they were.
So I changed to the measurements list screen and indeed the supercharger revs were 0. But I also noticed that the battery voltage was about 11.7V, which for my car under those circumstances it would normally show over 14V. Again I wish I had been paying attention to the other values but I didn't, however I feel fairly sure that I would have noticed if they weren't right.
Even though the car itself wasn't warning me of trouble I stopped to check the drive belts. Both were OK. So I got back in and started the car and it was back to normal with expected supercharger revs and battery voltage. I then continued on several journeys and everything was fine.
I had done an aggressive VCDS autoscan the day before and there were no faults. I have just done another one and there are still no faults. So the only reason I have to suspect that anything is wrong is due to those measurements shown on FIS-Control MMI.
