Thread: Battery Volts Reading on Nanocom Fluctuates

• My Air Flow reads 0 at all times. It should read at Idle 0 to 50 and 500/550 at 3000rpm
• Waste Gate Modulator reads 0 at all times. Look under TP should read 0 to 15 depending on revs

Thats what I have found so far. Now to tell the Minister of Finance about the expenditure as a result of the Nanocom.

Further developments: When I access the BCU, something clicks in the instrument binacle or there abouts & all the gauges die along with the windows, indicators & central locking. Unplug the Nanocom, & a few seconds later, all is restored. Also, at the same time I had the starter motor start the engine with the ignition in position II. All this did happen after a drive through heavy rain though. Had to pull R2 in the fuse box to prevent the starter motor running on. Can't find any water ingress but I can repeat the fault (except starter) in my driveway. I just don't know anymore
