No Aircon During Regen B8.5


Registered User
My Euro6 B8.5 aircon does not blow cold while the car is doing a regen, this is really annoying on a hot day. Anyone got a fix for it?
Today I had to park it up to let it finish it's regen while I had an ice cream in an air con cooled McDonalds, then it was OK afterwards!

How did it finish the regen while you stopped the car and went into McDonalds? All you did was interrupt it mid-regen and it will want to do another one soon to make up for the interrupted one. If it's doing a regen keep driving and let it finish properly.

As for your air-con issue, can't help I'm afraid.

Dunno, but it worked! No problem since. No fault codes so I guess it's designed to shut off the aircon while doing a regen.

You'd think it would stay on to put extra load on the engine.
