What can go wrong

On affected vehicles there may be defective battery modules which may result in a fire hazard when charging the high-voltage battery.

The fix

Update the software of the high-voltage battery to improve the self-diagnosis capabilities. Vehicle owners are advised to not charge the high-voltage battery using external charging sources and also not use the e-tron modes “Battery charge” and “Battery hold” until the update is applied.

Is a specific car affected? A recall lists models and build dates, not individual vehicles, so these pages cannot tell you whether one car is included. Enter the registration on the DVSA vehicle recall checker on GOV.UK, or give the vehicle identification number (VIN) to the manufacturer or one of its dealers. Buying used? Ask the seller for proof that any recall work was done.
