Remember that your contract for purchase of the car is with the supplying dealer, and for the repair with the garage who did the repair - not with Audi, let alone Saudi (sic). I presume that your original 6-month warranty period means that the car was over three years old when you bought it.

You'll need to look at the terms and conditions under which the replacement parts were sold to you in December, and whether or not there was a warranty with these. Despite its name, September is nine months after December, not seven.

I'm not sure from what you say whether your local Audi dealer has seen the car before you 'transported' it to them. If not, you can hardly expect them to do anything for free.

the Audi S3 first came out in 1999. Some indication as to the age of your car might be helpful.

From what you say, you bought it with a 6 month warranty. That warranty has now expired.

So looking at that, the car has no warranty, and it's down to you to pay for repairs.

The devil is, as always, in the detail. And your post is very short on the sort of detail that actually matters.
