Thanks for the reminder. I got carried away and went for a test drive immediately after unplugging I have driven it unplugged for a week now and no issues discovered so far. Other than I seem to drive more and more every day...

For others thinking of doing this, the vacuum seems to be on the plasic 'nipple' side and not in the hose left hanging around (see the pic in my previous post). So it might be worth putting something there to fool the system. Or do the zip tie trick like X3eme did his.

I might check if there are any fault codes activated now that I drove it unplugged.
