SOURCE: My 2005 Audi A6 3.0 TDI just keeps blowing hot air

I would first try getting the a/c system recharged. It can be a number of things, but having the system pressure checked is the first thing to check.

WHAT DOES THE BODY CONTROL MODULE DO ?


HVAC Compressor Controls Circuit Description
The operation of the A/C compressor clutch is controlled by the body control module (BCM) and powertrain control module (PCM). The BCM receives an a/c request signal from the heater a/c control assembly through circuit 66. The BCM then sends a class 2 serial data message to the PCM through circuit 1807. Power for the a/c compressor clutch relay is supplied by the A/C BFC fuse and circuit 439. When the PCM receives an a/c request message from the BCM, the PCM grounds circuit 459 allowing the a/c compressor clutch relay to engage. Ground for the a/c compressor clutch is supplied through circuit 450.
Do you know what a class 2 serial data message is ?
Class 2 data is a high speed data transmission. In order to control serial data line traffic, class 2 uses the peer to peer method along with message arbitration in order to manage the data line traffic. The class 2 data line includes the following control modules:
?€¢
The body control module (BCM)


?€¢
The electronic brake control module (EBCM)


?€¢
The powertrain control module (PCM)


?€¢
The sensing and diagnostic module (SDM)


You need a factory scan tool to diagnosis , it's the only way to see if transmission is sent an received !
The intake air temperature (IAT) sensor is a thermistor which measures the temperature of the air entering the engine. The Powertrain Control Module (PCM) applies 5.0 volts through a pull up resistor. When the intake air is cold, the sensor resistance is high and the PCM will monitor a high signal voltage on the IAT sensor signal circuit. As the intake air warm, the sensor resistance becomes lower causing the PCM to monitor a lower voltage. If the PCM detects an excessively high IAT sensor signal voltage (low temperature indicated), DTC P0113 will set.
Test the signal circuit of the IAT sensor for a short to voltage. Refer to Wiring Repairs in Wiring Systems.

Auto scanner code 1698


The P1698 code means that no digital data is being received by the powertrain controller from the transmission control module, located on the right inner fender. The manual says to check the CCD bus wires between the module and the rest of the system using the Chrysler diagnostic readout box. But if you don't have one then I think you can do the same thing by measuring for continuity (near 0 resistance) between pin 4 of its plug and pin 11 of the data link plug under the dash or pin 59 of the powertrain controller plug.
Then check the resistance between pin 43 if its plug and pin 3 of the data link connector or pin 60 of the powertrain controller plug. The powertrain controller is on the opposite side of the engine compartment on the left inner fender. These module plugs are held in place by a bolt. If the continuity between the transmission and the powertrain CCD wires checks to be ok, then according to the manual the trans controller should be replaced.
That is my analysis of what you report. You may have been told to replace the body control module erroneously because the code for that is P1695. If the independent garage was using the check engine light as its diagnostic methodology those problems both give a code 66, so they may guessed that it was the body module as being the faulty one. Problems with starting and with gauges are often related to this data bus communication system so all your issues seem to point this way. You might also, when checking the wires, also verify that they are not shorted to ground.
