Dear all,
I'm new here and I'm trying to find out some information before I go to and expensive mechanic.
I bought the car recently and it was winter so I didn't need it for cooling and couldn't test it properly when I bought it.
The issue is the following:
No matter how low I set the temp and how high the vent is going (recirculating or not) there is no freezing air coming out just normal outside air.
What I have tried:
- previus owner said he changed the compresor before selling and gave me the old one also (not original either).
- fill up with Freon, the car had only about 100g of Freon left and I topped it up at 525 as written under the hood at a specialized service. - Still the same
- somebody suggested that the pressure valve that should start up the compressor is not working. So I checked if the value coming from the valve (and read on the car CPU with OBD) is the same as the value in the pipe measured with a manometer. Both values were 6 Bar.
The guy told me that when you start cooling the pressure should rise to more than 6 bar and the the valve would fully start the compressor.
Does anyone have any suggestions as I would not like to change the expensive compressor and find out it's from something simple.
Thank you in advance
Also as a side note does anyone have the Superb Kombi Mk2 (B6) Service manual as a pdf or something. Thank you.
