VW and Audi Comfort Module Repair (VAG)

Window, lock, mirror, and interior lighting faults often start on the comfort module board. We find the failed component under the microscope and repair it on an ESD-safe bench in Ottawa.

Faults that look like wiring but start on the board.

The VW/Audi comfort module (Komfortsteuergerät), the central body control module on VAG vehicles, is one of our recurring bench jobs. A lot of what reaches us arrived as a wiring complaint in the bay and turned out to be a board-level fault inside the module:

  • Window faults
  • Lock faults
  • Mirror faults
  • Interior lighting faults

How we repair a comfort module.

We diagnose component by component on the PCB and repair the actual fault instead of swapping the whole module. The work happens on an ESD-safe bench with microscope-guided rework and controlled-temperature soldering. Typical findings are a blown capacitor on a power rail, a failed driver IC, a cracked solder joint, or a ground plane corroded by moisture.

Sending a module in.

  1. Call or use the inquiry form with the module name, the part number, and what the vehicle is doing. Photos and your tech's diagnostic notes go straight to the bench.
  2. Ship the module to us from anywhere in Canada, or drop it off in Orleans.
  3. After the bench diagnostic, you get a written quote.
  4. With your approval we repair and QC the module, then send it back to your shop along with the written summary.

Built for dealers and independent shops.

Dealer service departments, independent shops, and European specialists send us comfort modules alongside Audi MMI units. Your tech deals directly with ours. See how we work with auto shops or the full range of automotive modules we repair.
