From looking at that, having that £1000 allowance from the dealer (they pay £1000 of the £3000 deposit contribution, Audi finance pay the other £2000), having £7100 paid elsewhere "advance payments" (that would seem to be your £5k deposit, £2k from the Finance deposit contribution, and the £100 - perhaps from dealer discount?) - what's left on the car is £35474.80, plus interest for however long you have it, plus 58 days penalty interest. You'll be reducing that balance with every month's payments. In the early days, about £220pm of your £525pm will be reducing your car's balance, the rest is interest.
It looks to me that you have little to no dealership contribution (except maybe that odd £100 from the £7100), unless you already had it knocked off the RRP. Are you going with your local dealer, or Drive the Deal?
