Re: MCS failure warning on 3.2GT
Look under the top level forums theres realms of stuff on that warning, its an open book. I wish someone here new more about the logic, ie why it persists sometimes and not others, what a flashing light means etc etc
Myself have had it come on, garage said code said lamba, but when sensor tested no issues. Cleared, then on again a while later ( once on generally stays on - thats the yellow engine light ). Back to garage replaced lamba, OK for a few days, then back on for a few days then off, then on, now its been on for 2 weeks.
I'm ignoring now, never hickuped, never lost power. Always came on say 5 miles into journey, so I think in the system somewhere the lamba gets 1/2 readings and flags an error, I'm thinking so what now, its a momentary glitch. Its onbiously not the sensor and I think any other sensor would result in something I can 'feel'.
I don't think the garage farting around with it any more would help, only start replcing bits as a duty of trying. Issue is how you sell with a light always on ? With more data on eaveryones MCSF light I'm sure things could be categorised, probably better than a garage guess ( code analysis asside ).
There's nothing in the dark that isn't there in the light ..... except fear
