Can someone tell me all about this. Where to fill it, how to check it, what to fill it with, front and rear diff servicing, oil weights for diffs etc.

I do have a proper dipstick for the car so that should make reading levels a little easier.

Is the dipstick tube the silver metal tube that runs up the passenger side of the engine and is capped off with a blue plastic plug of sorts?

Wow thank you very much for that. What program were you using there?

not cheap and there is an annual charge, only useful to the trade as it covers all cars not just Audi and is linked to autodata when out on work to diagnose faults live via my laptop so is very powerful but a very high cost if your only working on your car, if you need any information just ask and ill put it up that way you get it free
