2006 D3 Audi S8 spares or repairs

Hi

I thought it would be best to post this here to avoid time wasters

I have for sale a 2006 Audi S8 5.2 V10

has around 130,000 miles, had an engine rebuild around 110k to the cost of 6.5k from Agnew Audi Belfast ( receipts to prove)

overall body is in good condition with a few minor marks here and there

2 main issues with the car are as follows:- audi media screen powers on brings up logo then goes blank all other buttons work 

suspension issue, when parked up drops its ride height and now struggles to lift, i don't have enough knowledge to even start messing around with air suspension and definitely dont want to pay any more Audi specialist prices  

Im not sure how to price the car but  i am going to start off @ 3k and see what interest i get.

Thanks for reading.
