Unless they looked why would they know its has an extended warranty.

Several years ago I had a Golf with an extended warranty and at 2 years old it required a water pump which they spotted leaking at the service and informed me about by phone. Never mentioned I had an extended warranty, assumed they knew since I bought it form them but when I collected the car they presented me with a bill saying they had submitted a good will claim, when I told them I had an extended warranty they cancelled the invoice. Some weeks later I received a cheque in lieu of the good will claim (which obviously they had not cancelled) for the parts and 50% of the labour, simply banked it. Paid nothing and got cash back, brilliant.

All you can do is hope that Skoda will do the decent thing, if not you are paying out of your own pocket.

Your purchase paperwork would have included details of the extended warranty, which could have been issued by the garage/Skoda or a seperate insurance Company.

The service dept. will have no record of any warranty, and if you failed to make the warranty claim at the time, then if the warranty period has now expired, you have lost any rights to claim against the warranty, unless Skoda offer a goodwill gesture, and they have declined to do this.

I think you need to revisit this with them.

Its not clear whether or not you had the work done. ultimately that shouldn't make much difference, but it might change the argument.

1) The fault occurred within the warranty, which you can prove.

2) You didn't follow their procedure, nor did you gain their authorisation for repair.

So I would expect them to accept the claim. However, I would expect them to pay no more than they could have had it fixed for. Which may be less that the figure you were quoted.

If you haven't had it fixed, then that should be no issue. If you have had it fixed then you probably need to bite on the difference.

Polite persistence is probably the approach.
