Audi Repair Questions? Ask a Mechanic for Answers ASAP
I'm sorry, I'm aware of this information. It's on a label under the hood.
According to everything I've read for r134a...
These are only approximate values, but, the low side should be around 27 psig to achieve just above freezing temps in the evaporator. The high side should be approx. 2.1 - 2.5 times outside ambient temp.
So...that gives me an acceptable high side range of around 193 - 230 psig.
If anything I'd go to say that the only thing that seems abnormal is the low side pressure...which is why I am seeking advice from an Audi specific A/C technician...thinking that maybe this particular Audi has an abnormal expansion valve setup or something.
Thank you for your reply, but if you are unsure of the specifics of this vehicle, please let me know.
And yes, this vehicle does have rear A/C as well.
