Twice bitten, third time shy

I bought a BMW 320i from Audi Sandton and was assured that the extended 2-year unlimited warranty covered ALL mechanical and electrical defects. <br> <br> Upon collecting the car, the auxi****y audio input fell trough the center glove box where it was housed. I was forced to call Audi Centre Sandton SEVERAL times without a call back from Jaun, and his only response to me was that I need to check my warranty policy to ensure the part was covered, and I discovered that indeed it was.<br> <br> Barely 2 months into ownership of the car, I found that it started overheating, with continuous warning lights about low coolant levels. I booked the car in, only to be told by SA Warranties that they do not cover the battery and switches for the engine fan. The repair on the car will cost R7000 that SA warranties is not willing to cover, in spite of my policy document stating the the engine cooling unit is covered.<br> <br> Both Audi Centre Sandton and SA Warranties refuse to take responsibility for a major purchase that now requires major repair within 2 months of purchase.
