Help locating Aircon High Pressure switch
 

Please can some help me by advising where the aircon high pressure switch is located? I need to disconnect it as the aux fan has failed on whilst I get a new one organised.
Not had any luck finding it's location on the forum / audi forum sites.
Thanks!

I believe it is where the pipe from compressor enters condenser radiator. But I don't understand the logic behind disconnecting it. It's there for safety to switch AC off if pressure rises too high.

Thanks.
The aux fan is killing the battery, hence disconnecting the switch will disable the air con and the fan from being on. I was going to disable the aircon until I can get the new switch fitted this weekend.
