Audi A4 SE 3.0L TDI Q
I tried my Air con today because it hasn't been on for a while as I like to keep it active even in the winter times.
But today on pressing the AC Button the Red LED only lights briefly while pressing the button and won't turn on??
Could this be a fuse gone? a pressure switch? or something else?
Don't really want expensive garage bills :-(
Thanks
It may need a regas.

Would that stop it being turned on?Quote:

If the system has low gas the pressure sensor stops the compressor from running, that stops the air con from ruining the compressor.
If a regas doesn't fix the problem scan the car for faults.

Well I had the system re-gased drove car away from Garage AirCon working brillently, left the car parked up for just 2 weeks, came to use it again today..... Same problem??? Surely it can't have all leaked out again in such a short time and they said that the system had no leaks?? What's going on?
Take it back for a leak test.

Did they tell you how much gas they put in last time? If they only had to top up the pressure, it could mean that you have a pressure switch problem. If a scan will help, I am in Malvern and have VCDS.

This is RPM @ Malvern, don't know whether you know them, they are very good I get the car serviced there now as Audi are a complete joke when it comes to thier pricing!! They wanted something like £183.00 per hour!!!!
and on my first service Audi charged me but didn't fit a polen filter, after that I haven't gone back to them!! They said they had changed it, when I took a look it was still full of dead flys lol.
I was told that the air con system doesnt show up on the fault codes? so I don't think a scan will help not unless you know different?
Thanks
Paul, I don't know different. I assume that is correct. If they said it was empty and filled it, they should have done a leak test first. They should do that now and perhaps without charge, though if they now find a leak, that will have been the original problem. Keep us posted please.
