V50 AC : AC controls need coding?

[gimbers]

Hello All,

I'm new here but have an issue with my 2012 V50 diesel air conditioning. Long story:

Summer 2019 was buzzing down the motorway when a mist started to come out of the central vents in the cockpit. I called Volvo assist and they said it was gas from the AC. Sure enough, AC not working.

Summer 2020 took her to my local Volvo dealership and they said their machine refused to gas because of a leak. Wanted to charge me up to £2500 to find the leak/replace the condenser and/or compressor.

I took her to an indy who said that the refrigerant smells, so the mist that came out of my vents was something else - just a coincidence. They successfully re-gassed her. They weren't sure what pressure to do it to, apparently the notice telling them what pressure to use was not present on my car, so re-gassed her a further three times at different pressures. They said they could get the AC to work using a computer, but the controls in the cockpit were not operating the AC. But it was working, but only from a computer. Also said the Volvo dealerships machine must have been faulty. Also said that the controls are coded to the system and only Volvo can do that. Charged me £45.

I have re-approached my Volvo dealership with all of this info and they do not seem to agree that the controls have to be coded. They are very vague, but not sure what to do.

If anyone has any pointers for me I would be most grateful.

Many thanks in advance,
