Bought my mk6 3 weeks ago from an independent garage, noticed a slight rattle/grinding noise on start up, plus it was a bit hesitant when accelerating at times. Took it to an independent garage and it has came back with a list of faults. 
Timing chain rattle
Swirl flaps open 
Both ball joints 
Turbo leaking on to driveshaft.
Big bill for parts and labour
So have went back to where I bought it and they have said they will cancel the finance and take the car back minus my old car as trade in as they sold it. 
There is 3 months warranty on the car, should I just cut my ties with the car or chase the warranty and get it fixed up
