Just had the first variable service at Northfield Audi, the whole experience being pretty good, I suspect mainly due to Northfield being flexible in their approach to customer service.
When I purchased the A2 12 months ago with 9K on the clock, the first thing was to get the used longlife oil out and some new clean 505.01 oil in it place which I have replaced every 6k miles. I also changed all the remaining filters ( air, plenum and fuel ) over the last 6 months, so when it came time to arrange for the service I told Northfield that I did not want the oil or any of the filters replacing as they had already been done.
They were quite accommodating asking for proof of parts purchased were original Audi and that the oil replaced was within spec, They said they would carry out an inspection service which would cost £138, and that the warranty would still be in place. I was quite pleased with this result as a full service would have cost about £360 including parts, which means I have saved approx £120 once I take into account the cost of parts and oil on top of the £138 charged by Northfield. Oh I also got a A3 2.0 TDI as a courtesy car for the day. I know that not everybody has either the time or inclination to carry out serving themselves but it does demonstrate what can be saved.
BTW I did notice that the Service indicator had been reset but the mileage to the next service is now 9500, I will watch this carefully over the next few weeks as I guess they have reset it to Fixed rather than Variable service.
