audi a3 1.8 tfsi Broke down two times

I bought a new audi a3 in july 2013. Desember 2014 the car brokedown on me. They towed it in and they told me it was the multitronic that had to be replaced. 3 weeks later i got the car back, drove 100%. Went to durban on vacation on end desember. A few times the car showed eps on the dash and had no power. After a few times it stoped, until it just died in town one day. They towed it in again, and the feed back i got was that they had to replace the main electrical wiring and ecu. Its standing for 3 weeks now. I paid R410 000 for a new car that keeps breaking down on me and i can not ever trust my own car to take me from point a to b. As it looks now, ill never buy an audi again.
