Time to put the iCarsoft on the CLS63, I thought, so plugged it in and turned the ignition on. Ready to start the scan, so I then started the engine...
WTF! All the dash lights on, the front and rear parking sensor displays flashing on and off, the rev counter and temperature gauge (and speedo when I later set off) needles jumping up and down in time with them, lots of spurious warning messages, starting with a red 'DO NOT CHANGE GEAR CONTACT SERVICE' or words to that effect. Park Assist. ESP, ABS, Brake Hold, Power Steering; all, plus others I can't recall, were generating warnings. The jumping needles were jumping up towards their correct positions, then dropping back to zero. The fuel gauge needle worked normally, but nothing else did. The engine was running fine.
Switched off, back on again; no change. Third time lucky? Yes, all OK.
I did the iCarsoft scan on automatic; the scanner went right through everything, but no results, just back to the automatic/manual option screen. So I went through on manual scan, and there were scores of fault codes, all bar one stored only, mostly relating to communication loss between the instrument cluster and either the CANBUS or the front SAM. I cleared them all, except the RH mirror heater, which was current and stored, then switched off the engine and put the iCarsoft away.
Left it a couple of hours, then started the engine again. Full WTF mode again! The engine seemed fine, so I thought I might as well try driving. Instruments still in WTF mode, but that apart, it drove perfectly normally. I switched it off and on a couple of times (while stationary, silly), and everything returned to normal, though the amber EML was on.
This morning I ran a scan and cleared all the codes without starting the engine, and everything was normal; no EML, and the only current fault code is the mirror heater.
Note to self: Do NOT start the engine with the iCarsoft connected. - on this car, it looks as though it doesn't like it.
I've just been out for a run, stopping and starting the engine four times, and everything was normal, so it looks as though it's OK now; the glitch, if glitch it was, is gone.
If it happens again, I'm minded to try forcing an ECU reboot by disconnecting both batteries for ten minutes. Can anybody with a W218 or a W212 tell me what settings I will lose if I do have to do that?
