any advice on buying a4?

Since this is refering to the b6 model , Im pretty sure that the 5 speed tiptronic was replaced by the CVT on all models (Im yet to see an A4 b6 with auto box) . Biggest issue is the control unit on the back of the box which is around a $3-4k repair .

Other common issues are :
Breather hose on rocker cover perishes
rocker cover gasket leaks
rear coolant flange leaks
upper control arms start knocking (usually after 100k+)
Tie rod ends start to sag
Interior plastics on switches starts to peel

Oh , any odometer can be re-set with the right equipment , and yes there are people here in Sydney that have this equipment

Ah my bad, Bug Racer well spotted mate. Ok ill have a spray about the B6 then CVT ( Multitronic) or fondly known as Faultytronic has an issue with slipping. Early in the piece we were fitting Valve bodies and flashing the ECU. Now that all that has been done the biggest thing is a lack of servicing. It is done at 60k but many miss it. You are right the Ecu inside the box are bad for faults too and you must wear an earth strap when changing as you can damage the printed circuit. There is a company doing CVT recos for $3000 warranted for 3 years which isnt too bad but bad enough i suppose. Company is in Melbourne and he specialises in CVT and only one other i know is in the UK. Yes the coolant flange at the rear of the head is shocking for failing. ALT engine which is the 2.oltr can drink a bit of oil. Again like any Audi check the history and have the cam belt , tensioner and water pump done in one hit. The radio, window switches, headlamp and other dash switches all peel, get new ones and they do the same.
Yeah there are people up here in Brizzy too with the nesc software for dashes. On that like BUg Racer says ANY elec clock can have things done with the right gear and software.
Cheers
Oh and by the way B6s look tops with A8 replica wheels!!!!!!!!!!!!! and dropped a bit too
