End of November we picked up our new MYLR having had a M3LR for around 18 months, which performed perfectly.
We always run our HVAC on Auto, and noticed that for the past week or so the car was switching autodefogging on, whether (in our view) it was needed or not. And that the autodefogging would not switch itself off, the car interior becoming like an oven. The cure was to switch the HVAC off completely, then switch on to manual, setting fan speed down to 3.
we weren’t sure if this was (a) a software issue - given that the M3 only got autodefogging after a software update, (b) user error, (c) a problem with the humidity sensor or (d) something else. So on Monday evening I logged the problem on the app and almost immediately was offered an appointment for this morning, which I took at Leeds.
it took them a bit of time to track the problem down, having eliminated a number of things which of course takes time.
eventually they tracked it down to low gas level in the air on system, although there was no evidence of leaks anywhere so one can only assume it was a factory build issue..
anyway, heating etc set on auto for the journey home, where it was -1 degrees outside and definitely would have previously made autodefogging kick in. So I reckon it’s now fixed.
thought I’d share this with the group as I know others have had similar problems, and this may be their cure too.
TLDR: autodefogging not switching off traced to low gas level in air con unit.
