Not just 120.000km and not always. Most affected are early models, facelift seems to be more or less OKish. Stronic is QUITE the magnificant when it works, for the most of the time, but it is fragile as hell. You are not entirely correct, with 3.0 diesel setup it is really zero lack of power issues. One of the mechanical issues is that S-Tronic does not enjoy traffic jams and it heats up very easily, because changing from 1-2-1-2-1-2-1 gear for prolonged time renders a disastrous lava hot oil explosion and dead control unit. That control unit and labour does not cost marbles.. IF you need better choice, there is other option - at least the 3.0BiTDI version of 313HP and RS6 has a different gearbox - conventional and great ZF 8-speed automatic gearbox and you wonder why? Because S-tronic cannot handle that much Nm.
If somebody mentions FWD model, haha, go and F yourself with that garbage + multitronic.
For more of my honest automotive thoughts, please see my blog.
Point taken, the detail with the traffic jams and 1-2-1-2 gave me good idea what could happen and that is good to know.
Well.. basicly I haven't mentioned a front wheel drivetrain anywhere. technically speaking I agree that RWD is much better but let's be honest - not everyone can drive RWD. I mean I am looking the things at the manufacturer's point of view.. they must cover every style of driving, every need of the customer.
..Btw, you do remind of Jeremy Clarkson :D
