Not a mechanic so I cannot say 100% about any physical problems other than what I have experienced while performing updates. Personally I always suggest the software update route first as it tends to be the fastest a cheapest way to start a process of elimination. For your ECU the most up to date file is: 8036.
Cool. I was under the impression that as I had a dsg with software 7001 that was the latest version. If I have no joy with local dealer I’ll pm you
