At the shop right now... Condenser is leaking, damaged by some small stone or something... Now waiting for the verdict if the garage is paying or not. Was sold with statement they replaced a couple of pipes because they were leaking and was 100% working when I bought it. Since it was -10 a month ago I got cold air out of the ventilation but most likely not from the airco but just the outside air. Fingers crossed... Mike.

Update: they replaced the condenser this afternoon and I will be able to breed polar bears in the FFRR now... However, another problem surfaced: the pressure in the AC is building to 25 bar and the fan is not activating to cool and reduce the pressure. They think it could be a malfunctioning pressure sensor which activates the fan or a loose contact but they have to check tomorrow morning... Run out of time this afternoon.

Thanks Stan!! Hoping indeed someone already had this problem before and can share some information how they replaced it, where they got a replacement fan from, etc. Any help is appreciated!! Mike.

Before you go and buy a fan I trust you have connected a wire to the fan +ve terminal on the fan and the battery +ve terminal and checked the fan is adequately earthed.

Yup they did test all possibilities but the fan is just not moving... The pressure sensor is also sending the signal but apparently the module which translates the signal into what speed the fan is suppose to turn is not functioning anymore. Apparently this is one with the fan so if the module is kaput then you have to replace it completely, doesn't come separately... Unfortunately...

The fan has a permanent 12v supply and is activated by signals from the ECU through a 3rd wire. It is not possible to test by connecting it to the battery. I had a similar situation where the fan wouldn’t start and the freon pressure kept going up. The sensor was OK, the fan could be activated with the testbook but it just wouldn’t spin when required… Of course the service guy said this was normal, but when it was very hot outside, the air conditioning kept stopping… I decided to fit a different fan, a simple one with just on and off and not 900 different speeds and that is started by a relay commanded by the pressure sensor… Total cost of operation, about 50 EUR... |

i'd double check the connections to the fan Mike, its possible that when the garage peeps fitted the condenser they could have dislodged the wiring somehow.. ... - .- -.

Thx Adara!! So what do you mean with the fan could be activated with the testbook...? Not sure what you mean... Mike.
