. I too have received two letter in the post and a phone call this morning about DSG Service which was done 2.5k miles ago and is already on the system. There is definitely something wrong somewhere with these stealerships 
No one seems to read them. Perhaps we need to test this with something like "the service advisor slapped my wife".
I'm now thinking maybe I should add the aircon to my upcoming fourth anniversary service. It was done at year two, so it'd be consistent.
Jeff I waited until it didn't seem to be working efficiently anymore before doing this. I believe the book says it's due at 2 years old and every 2 years after that. However I'd rather not give Audi more money than necessary and they never mentioned it. Cost 35+VAT for the air con bit of the service.
I can see the logic of not troubling trouble til trouble troubles you. On the other hand, with most other aspects of the car, many of us here tend to over-service as a preventive and/or risk reduction measure. I lean towards doing the same with the aircon.
Try saying that after a few shandies.
We're of like mind Jeff, however for me it totally depends on what the service involves. Where there are consumables which have progressive degeneration such as oil, filters and tyres it can be argued that early replacement is beneficial to continued reliability and performance. For other components the argument is a bit more difficult. For example spark plugs and brake pads. Early replacement of the former is easier to justify than the latter in terms of those benefits. This then leads to the question of risks associated with the act of servicing (an ideal example of which is my attitude to having the CREC recall work done). I'd guess that a search of the forums on this site would quickly find posts along the lines of "I took my car for a service and this happened..." Even a good tech might open up or dismantle something and find that something unexpectedly breaks due to the act.
I think your own test applies here @Dippy. Roughly 10% of the refrigerent is lost every year naturally, plus there's always scope for that to be increased through leaks. If too much is lost, the system will struggle to maintain cabin temperatures in summer and demist effectively in winter. It also adds strain to the compressor because the refrigerant is used to cool it. If the refrigerant levels gets too low, the compressor could overheat and maybe fail, or
3 years old I'd say it's done, and done its job. I'm totally fine with that. The wear and tear the car picks up means I don't want a 5 year plus coating. It needs a light polish to fix the blemishes. What I hope is that the coating takes most of the abuse rather than the clear coat.
@Tashfeen - ^ filthy !Very likely. I am also inclined to think that this is the case.
Don't get me wrong, whilst the cleaning might not be as I would have liked it to be what I do like is that the car doesn't get that much dirty. The rain kind of cleans it all. In the below pictures, the car has not been washed for the last 7 weeks, driven nearly 1200 miles all of them in the **** weather including the brief 'summer spell' we had however, its still not bad.
Let's see what Nick says.
you'd have driven it a lot more as it is a fun car to drive. Wish I could say the same about S5 
@scotty76 - Job well done mate
Yeah I park next to a tree and the car lives outside at all times so is exposed to the elements. Fortunately the tree is evergreen so these are blown leaves from other nearby trees.
