Time for a major, major service!

Personally I'd probably wait a bit longer, I thought 7 years was more the cambelt life and you "could" lengthen that if mileage is below average.

Though I would do "the full monty" with plugs, filters etc. - in for a penny in for a pound (times a lot!).

Not really sure why you are doing this now......

Audi recommended time interval for cambelt is 5 years - admittedly the previous owners left it to 8 years before changing! I was happy to extend it by a year based on my low mileage, but if I decide to advertise the car in the next 12 months without the belt done it's going to knock the value fairly considerably, I would've thought?

Maybe, but by as much as it costs to do the work?

Not a thing I would do yet, and if I was selling I'd research the market first. You may find a potential buyer like Ainars who will be planning to do the work themselves and would prefer NOT to have recovery of third-party labour costs factored in to your price expectations.

I bought my current S8 knowing it needed all this doing and discounted the price appropriately, both buyer and seller were happy. But it did allow me to run the car for quite a a while first to decide what else needed doing, before confirming that it was worth spending all that money on it.
In fact I did get the gearbox fluid & filter changed relatively quickly (serviced by Audi so obviously never touched) but left the major service for a while longer.

When I first replaced belts (all belts) on mine I did just the belts, opened up roller bearings and put fresh grease in them. Later I saw 2 of the same design 32V engines where cambelt had jumped because tensioner damper was old and not working correctly. This scared me so I decided to replace mine and replaced cambelt again about 2 years later as it's cheap enough to replace as precautionary measure and could be very expensive if it fails, I think it was less then £30 for Continental belt. Second time around I re-greased cambelt roller bearings again but replaced 2 alternator belt rollers as they were past it's best. I will probably do cambelt and re-grease bearings again this summer even if I have only done 17k miles in 8 years. Have not replaced or done anything to water pump. Replaced thermostat once but not as part of belt changing as I have luxury of being able to replace it without belt removal on 32V. I do all the jobs myself so don't have to worry about labour costs, if I had to pay somebody for the job my strategy would probably be different.

I don't think spark plugs need replacing that often, I have done mine but they will probably be OK for 100k. I went for after-market NGK Iridium as they worked out cheaper than OEM and I believe they should be just as good or better and last longer than OEM.

Air filter I replace every year together with oil service even if I only do 1-3k miles, it's only like £10 or less for MANN filter.

The previous change was indeed all OEM parts - maybe I'm being overly cautious then?
