Audi A3 – Aircon Pump

Audi A3 - Air Conditoning Compressor Electrical Connector

The Air conditioning was not working on this 2003 Audi A3. Diagnostics revealed that the Air Conditioning compressor was not operating.

Careful investigation revealed that although the switch, fuses and relay were OK the electrical feed was still not getting through to the compressor.

The fault was traced to the feed cable close to the plug that connects to the compressor itself on the front left hand underside of the car.  The insulation had been damaged for some time thus exposing the copper strands to the elements. These corroded eventually breaking the electrical circuit.

This was simply repaired by a soldered joint finished with heat shrinkable sleeving over it. The image shows the cable ends prepared prior to the spliced joint being made.

Audi Q7 – TPMS

Audi Q7

This customers vehicle was found to have “siezed on” valve caps and is fitted with a Tyre Pressure Monitoring System (TPMS). As replacements are only available as a very expensive new assembly and require re programming of the vehicles electronic control modules we found and sourced replacement valves.

As can be seen below the old valve on the left is heavily corroded on this 3 year old vehicle probably due to this winter’s salted road’s !
