Returning a lease

[Monkeez]

Hi all, my A4 is due to go back later this year.
I've been through the contract paperwork and it doesn't state that the car has to be serviced at a main dealer, just that it has to be maintained as recommended - so i had it serviced by an independent that i know and trust.

Also, the paperwork doesn't state what fines/charges there are for any missed maintenance/service work - should it have stated what they are?
I haven't missed any work - i'm just preparing myself for anything they might try to come back at me with.

The car is through Arnold Clark not Audi finance.

Thanks

Hopefully it will not make a difference but the recommended is usually oem parts etc and I suspect your local garage used 3rd party parts. Hopefully some more knowledgeable answers soon.
