Audi A3

Hybrid drivetrains with DKZF place increased demands on the DSG gearbox through the interaction of combustion engine and electric motor. Gearbox failures from as early as 80,000 km have been documented.

Symptoms: Juddering on pull-away, unusual shift hesitation, gearbox warning light, in worst case gearbox no longer shifts gears

Audi recalled Q5 and A6 PHEV models with DKZF drivetrain: defective cell modules in the Samsung SDI battery can overheat during charging and cause a fire. Recall code 93AB/93AD.

Symptoms: No driver warning before overheating possible; after software update, reduced charging capacity as indicator; in extreme cases smell of burning or smoke

Faulty charge port control units report the plug as inserted when it is not. The vehicle refuses to drive. Workshops often have little experience with this defect.

Symptoms: Message 'Charging cable connected — driving not possible' despite cable unplugged, vehicle will not move, onboard system fault message

In PHEV mode, the combustion engine rarely reaches operating temperature on short trips. Cold-start enrichment allows unfiltered petrol into the engine oil; oil becomes thin and loses lubrication effectiveness.

Symptoms: Oil level rises despite normal driving, fuel smell from the engine, increased fuel consumption when battery is depleted

20,500 vehicles worldwide (6,700 in Germany) were recalled. Adaptive front seat belts may provide reduced restraint force in a crash.

The passenger occupancy sensor (PODS) may erroneously deactivate the passenger airbag even when someone is sitting in the seat. Vehicles from 2020 to 2022 affected.

The plug-in hybrid battery of the 40 TFSI e costs around €12,846 to replace — a significant cost risk for older vehicles outside of warranty.

Early 8Y models (2020–2022) suffer severe software issues: Virtual Cockpit, head-up display, SOS emergency call and multimedia system fail sporadically.
