Touareg / Phaeton / Porsche / Audi A8 Kessy Service

The Phaeton KESSY (Keyless Entry and Start System) module failure is a common issue in Volkswagen Phaeton vehicles, particularly as they age. The KESSY system is responsible for the vehicle’s keyless entry, start/stop functionality, and anti-theft system.

 

Symptoms of a Failed KESSY Module:

 

  1. No Response from Key Fob:

    • Keyless entry and push-button start don’t function.

  2. Car Won’t Start:

    • The car may fail to start even if the key fob is inside the vehicle.

  3. Error Codes:

    • Scan for error codes that are related to KESSY or immobilizer faults.

  4. Key Fob Not Recognized:

    • The system fails to detect or authenticate the key fob.

 

I can clone / extract data from most Kessy Modules, or even repair if they are not water damaged. Get in touch if you have any of the above symptoms.
