[Biturbos4] How does the 'service in xxxx miles' work ?

[Mike Kuriger]

In my opinion (and experience) if you only service your S4 when audi 
"recommends" it then you are likely to shorten the life of your engine.  
10,000 mile oil changes are what audi recommends, however even 5000 
miles is a stretch on a turbo engine.  I have never seen that service 
message come up since I get mine done every 2500 to 3000 miles.  Well, 
at least for oil changes...  If you 've ever taken the valve cover off 
an engine that has had oil changes past 3000 miles, you would know what 
I mean.  lot's of burned on oil residue coaring every single part.  YUK!
