Audi eTron electrics, service and spare parts supply is a complete disaster

I bought an Audi eTron Sportback S new in August 2022 at a list price of R2,662,000.00 at the Audi Audi Centre Century City in Cape Town. Unfortunately the electrics, service and spare parts supply is a complete disaster. The battery cannot be charged in an optimized way and as a result the maximum capacity (maximum range) is continuously reduced. This fault was first reported in July 2023. The car was in the workshop for almost 4 weeks in July/August 2023. The necessary spare part was installed in October 2023. In the long term, the error occurred again and a further attempt was made in February 2023 and currently in March 2023. The workshop cannot give a binding repair date and is only able to provide a Q2 as a loan car after massive pressure. I think every interested party should know that neither the technology is sufficient nor the service from the Audi Center Century City can be recommended. Friends of mine drive electric vehicles from BMW & Mercedes without any complaints. Too bad the design was more important to me and I made the wrong decision.
