Title: Heater blowing hot OR cold, nothing in between.
Post by: ksamyui on April 30, 2023, 04:56:57 pm

Got a bit of a weird one going on.
I’m getting nice cold air on ‘Lo’ setting, but 16° all the way up to Max is just the same hot air. Any ideas? Last time I checked on VCDS there were no errors.

I wonder if you have a dodgy interior temperature sensor? if its reading too cold all the time it might be trying to heat the cabin up to 16 or above.
Can you measure the temperature it is reading in vcds?

Yeah I’ll plug VCDS in when I get a chance. I recon it’s either that or the flaps are stuck open behind the glovebox
