Unable to calibrate climate control

Looops · Mar 10th, 2016, 11:57

Hi all.
Recently got a XC90 D5 2006MY and it had the usual problem of hot/cold/hot/cold heating. It had a code for Air Quality Sensor (CCM-0040) which wouldn't reset so I changed it (for a VW part which is identical and only £20!). AQS error has gone.

Now the foot wells are cold and the upper air is hot. Also the passenger heated seat has stopped working. When I try to recalibrate the CCM with Vida Dice I click Start and it just sits there with no progress. There's no other CCM codes except that the CCM recalibration failed. There's also one for the phone module battery but that's for another weekend.

Cheers.

Not sure but maybe the VW part is in fact not identical and its not being recognised by VIDA. Wonder if anyone else has had success doing the recalibration after changing to the VW part?

I can say with almost 100% certainty that it is the el-cheapo VW sensor that is the root cause of your problems.
I had the exact same problems recently, thought the sensor was ok, wasn't throwing fault codes up, had been using a Chinese VW sensor for a few years without any apparent problems, was struggling to find the cause of no heated seats/ cold air on the passenger side only, and as a last resort I plugged back in the original faulty genuine Volvo sensor, and bingo.... Heated seats/warm air are back.
It seems the cheapo sensor was/is throwing out corrupt signals and taking down the passenger side seats and heating.
So at the moment I've got the duff Volvo air quality sensor in, but can live without that feature, although if anyone finds a source for genuine Volvo sensors without spending £170, please let me know.
I did post on this subject a couple of months ago if you do a search.
