a3 3.2q software update trouble

hi all, i currently have a 05 3.2 in at the moment which has when running for around 10 mins what i can only describe as a violent misfire on tickover and unable to keep steady revs up to 2,500 rpm, above that it appears to run fine, once revved over 3k the engine takes a few secons to start missing again, so after scanning for faults which where all cylinder misfres/ random multiple misfires and bank 2 02 sensor 1 , we changed the following over the past few weeks to try and cure this problem, all coil packs, bank2 02 sensor before cat, both cam sensors, crank sensor, air flow meter and checked chain timing, all to no avail until i came across the posts on here about a software update, so rang doncaster audi to see if this update can be carried out and they say there is no update available for this car, has anyone had any joy with solving this problem via a dealer in the south yorkshire area as doncaster audi want to waste loads of time and money to diagnose for themselves first, cheers guys

yeah been through the thread a few times, do you or anyone on here know who they dealt with at huddersfield audi and when?

any one??

well it seems i may have had a development today with the a3, after checking various measured values i came across block number 091 which is for inlet camshaft adjustment, so on cold starting the specified value was 5deg and actual was hovering around 6.5 to 7 until it started running like a sack of spanners then it steadily increased to 52deg, so after a little more research in checking supply voltages and resistance on both solenoids which all appear to be good i then unplugged the inlet cam adjuster solenoid while running and the car now runs perfect and the value is at 0deg until you plug it back in, so theoretically is this a solenoid problem constantly allowing oil flow to the cam sprocket as i would of thought if it was a mechanical issue it wouldnt make a difference as to wether its plugged in or not, any thoughts on this would be appreciated
