Audi A6 3.0 TDi Q Allroad - Service Schedule Unclear - Newbie

[TVR500]

Although on my 4th Audi I have recently purchased my first A6 Derv in 3.0TDi Q Allroad flavour 2008/9. The manual/web is scant & unclear about what exactly is fitted & what is required for servicing ie one size fits all.

Mine is 4 years old with 70k & FSH, however, I want to complete all that needs doing upfront so i know its been done for the duration.

1) What Quattro system is fitted to Allroad -Haldex? manual says no fluid changes!
2) Tiptronic 6 Speed- fluid changes unclear 38k or sealed? Indy says no!
3) Chain yes but timing & drive belts - unclear changes?
4) Pnuematic dampers/compressor - any maintenance/longevity?
5) Glow plug replacement or wait until fail?

Any help or insights appreciated

1) proper traditional torsion Quattro
2) change the fluid, I have the same gearbox and running gear in my A6 C6 and have just paid £1800 to have it rebuilt - regular fluid changes would have prevented this (specialist words not mine)
3) engine is chain, but the high pressure fuel pump has a belt (not service schedule for this) if it ever were to let go don't worry, all that would happen is the engine would cut out )
4) you have air suspension
5) wait until one or two flag faults then replace all (in my judgement)

Perfect info thanks.
Suprised at your Tiptronic rebuild comments what sort of issues were you experiencing and at what mileage? My local indy suggested its sealed & not subject to contamination & should be left at least until 100k. I realise its a specialist job as it needs to be vaccumed out and so not cheap. My own had the 40k service done at a main delaer and while the manual says 38k for a change they did not complete this! Clearly with your experiences I'm inclined to do it!

What about torsion diff oils change periods?
