Klima, Druckschalter, austauschbar, OHNE Klimagerät?

HI

Here at the holiday destination, I have an A6 4G that started having problems with the air conditioning for the last 200 km of the 1200 km journey. The button seems to be malfunctioning:
[code]
1 Error found:
00256 - Pressure/Temperature Sensor for Refrigerant (G395)
004 - No signal/communication
Freeze Frame:
Error Status: 01100100
Error Priority: 3
Frequency of Errors: 4
Lost Count: 41
Kilometerstand: 84493 km
Time: 0
Date: 2014.07.26
Time: 17:13:00

The switch should be the one at the front, behind the air conditioning grill?

Can it be replaced without the climate oil escaping, i.e. without special tools for that?

Thank you.

Normal, yes. Take it out, put in a new one, and throw the old one away

Yes, when unscrewing quickly, very little refrigerant comes out, and the same applies when screwing in; first, grease the new O-ring with compressor oil and then screw it in quickly. There is a valve located under the pressure sensor.

OK

dann die nexte Frage:

How do I get 4G?

I can see it through the grill. But it seems the gatekeeper also has the key to the grill.

Okay, turn off the grill and I have the various... Cooler ahead of me, is not.


Alternative: Or, if the item is reported as defective, I can verify it.
Pulling the plug won't "fix" the problem, that's for sure.

Okay, here's the translation:

Okay, here's the translation:

Audi is cooling down again.

The sensor was quickly removed and reinstalled.
