That's what worries me, if I take it back will they be able to sort it.
I have three options.
1. Take it back until they sort it out (if possible)
2. Go back tomorrow say they have made a hash of the car and get a refund.
3. Take it to the dealer I bought the car from and hopefully they can sort it.
I know on my MK5 the dealer had to replace the steering rack under warranty, the car needed a full alignment afterwards and they left it perfect.
