Code: 00785 temp sensor in instrument panel
Is this located in the climate control head? And if so, is the sensor replaceable or is the entire control unit one piece that needs to be replaced?

let's try something first:
<i>When posting questions related to a problem you are having with a particular car, always state the exact make/model/year/engine of the car you are having a problem with. Also state any modifications you have made to the car. Incomplete information will often get you no answer, or worse yet, the wrong answer.
When posting questions involving trouble codes, post the complete code(s), and the text that comes with them. Do not omit anything, and don't drop any digits, not even a leading zero! Make sure to mention which controller (Engine, ABS, etc.) had the fault code(s). VAG codes are 5 digit numbers, unlike Generic OBD-II P-Codes, which are the letter P followed by four numbers. If you have a diagnostics question relating to VAG-COM or one of the factory tools (VAG-1551, VAS-5052, etc.), feel free to post it here. If you have a diagnostics question relating to an Autozone scan, it should be posted in the AudiWorld Autozone Forum ;-) or in a forum relating to your specific vehicle or engine. Any posts that do not pertain to VAG-COM or VAG diagnostics will be locked or moved by moderators.</i>

2001 A4 1.8tqm. Code is complete and a 5 digit VAG code from a VAG-COM, not a generic Autozone code. It is from the climate control unit for a temp sensor (G56)intermittant operation or short to ground.

* Open or short circuit between G56 and E87.
* G56 malfunction.
It suggests the following further actions:
* Diagnose and repair open or short circuit using wiring diagrams.
* G56 electrical tests (which appear to require a 1589 "break out box".
G56 itself appears to be part of a switch mounting plate. Replacing it would appear to require removing the radio and the "center section of the instrument panel complete (trim and supports)".
