Volkswagen
Polo Vivo 1.6 Trendline 2012 Model

I bought my brand new Polo Vivo 1.6 Trendline in February 2012.

Since then the car has been in for repairs twice where they have replaced something called gearbox mounting twice and engine mounting once. Also both times when the car was taken in for repairs the wrong parts was ordered. Please note that the repairs was done at different branches each time.

Now not even two weeks after replacing the parts the previous time I am hearing the same sound again.
This sound can be heard when going over a speed bump.
Plus a extra weird sound when I am changing gears. It sounds like there is a filter on my car.

Really really over this brand new car giving so many issues as I am paying a lot of money ever month and have never really seen the value for my money.
I now have to take it in for the third time and this really causes a lot of discomfort in my daily routine.

Please can someone contact me with a solution to the above mentioned.
