By Tim Iezzi, MACS Technical Correspondent 24 ACTION * June 2017 Audi W e recently worked on a 2013 Audi A5 Quattro with the 2.0-liter (engine code CPMA). It came to us from a local body shop that made repairs after the vehicle had been in a front end collision. The work performed at the body shop involved replacing the radiator, condenser and intercooler. After completion, the complaint was A/C inop. The body shop brought it over to us as they waited for a bumper cover and headlight. The car was still rather disassembled, making my work that much easier. The car had a smashed pressure sensor as a result of the accident, along with related DTCs. The refrigerant pressure sensor (G395) communicates with the VESCM (Vehicle Electrical System Control Module, J519) via a LINbus along with the humidity sensor. What's interesting is Figure 1: Although still first generation, 2013 was a facelift year for the A5. New lights, body details and paint finishes were offered, which included a new front bumper design.
