air con not working - Help!
« on: October 08, 2012, 06:05:05 pm »
Yet again my car strikes again, this tim ethe aircon isnt working.
I did a VCDS scan, and it said 00229 - low pressure
I took it to kwik fit, who said they drew 400grams out, and put 530grams in, and it had no leaks.
So it only leaves the pressure switch or the compressor.
Am I correct in assuming the switch is the one that you can see behind the radiator pointing upwards? and I can change this without letting all the gas out?
or is it a waste of time, and I just need to pay for the compressor? Does anyone happen to know the part number for the switch by any chance?
Thanks in advance for any help :happy2:

i hope kwik fit didnt charge you for the air con recharge then,, if i remember right the policy is that if they do not decrease the cold temp of your air con by over 10% then you dont pay,,,,, if in doubt phone their head office,,,,, just a thought but not a lot of people in kwik fit know how to do the air con recharge properly which was down to the bad training ( i was on the training course when it started ) lots of people do know how to do it there but a lot dont as well.

Yes you can... the part where the pressure switch screws into has a valve in it.  :happy2:

good, do you have a localgarage that can re do it or maybe they can check if the compressor is faulty before this ?
looks like you may have to fork out for a replacement if you want the air con back

Is that the sensor behind the headlight area?

I'd rather try the sensor before the compressor to be honest

Before you buy a switch Dom check the power to the pump very easy to pop the plug and do this first, think I've swapped one switch ever on your platform but fitted loads of pumps, costs nothing to check, let me know if it is the pump, got a few good used in stock (it pulses by the way)

Just for info my air con fault turned out to be the switch, was around £50 from VW but i guess the pump failing is more common

Wouldnt a failed pump throw a different fault code?
