The Audi Lie!!!!

I was introduced to Audi by my younger brother, a loyal Audi driver for over 10 years. I paid cash for my brand new 2014 Audi A4 TFSI which I bought in full off the showroom floor. In 2015 I was invited to an Audi Golf event. As I drove home I was hit by a hit and run driver. The damage was over R200,000. My insurer Auto&General insisted that Audi South Africa said they would repair the car. I insisted the car be written off, but was given no choice. Upon receiving the vehicle back after many months of repair, I have had nothing but problems with the car! Before taking the car back to Audi Service for the 3rd time, Auto&General requested I bring the car back to Audi Repair. That was nearly 2 weeks ago on the 3rd of February. I was told in the second of only 2 calls, that there is a hole engine system \Not caused by the accident\" and is a \"Factory fault\". I'm not a qualified mechanic, but no one needs to be to see that I am getting DUPED! Both by Audi South Africa and Auto&General! Are they that desperate, that they would struggle to piece together what is clearly a LEMON?? Audi South Africa assured my insurer they could repair my vehicle as new- you ****!! Thank you Audi. "
