Audi A3 E-Tron Diagnostic Report

In the reported instance of Audi A3 E-Tron cutting out, the vehicle arrived after intermittent power losses and multiple warnings (transmission warning and gearbox overheating). A fault-scan revealed code P288400, engine disconnection clutch stuck open. Investigation focused on the mechatronics unit (which handles transition between electric motor and combustion engine in the hybrid drivetrain). On removal and inspection, a broken gauze was found inside the mechatronics unit’s clutch gallery, obstructing proper operation.

Audi A3 E-Tron Repairs

The repair work for this Audi A3 E-Tron cutting out issue included:
  • Removing the mechatronics unit for inspection
  • Cleaning and removing the broken gauze material inside the clutch gallery
  • Testing the solenoid and clutch control for correct operation
  • Re-fitting the mechatronics unit, charging the hybrid battery pack, and performing a comprehensive road test to ensure smooth transition between electric and combustion drive

Resolution

After the repair, the Audi A3 E-Tron cutting out issue was resolved. The vehicle no longer cut out, all warning lights cleared, and full drive-function (both electric and hybrid modes) was restored. The customer’s confidence in the vehicle was regained.

Having been disappointed by my local Audi dealership, I came to LKQ Electriq with a disappointed view of specialist garages. I’m pleased to say my experience of LKQ Electriq and, in particular, my interactions with Kayleigh have restored my confidence. Without doubt I will return to LKQ Electriq in future for my Audi needs.
Thank you!
