Hi stoddy, Had my 3.2 for nearly six years now and still enjoy driving it, mine has also done exactly the same as yours with the stalling etc but fairly infrequently, the first time i did get it diagnosed at main dealer but i dont remember what it was they said,car did the stalling thing last November and twice back in January this year, thought i will get it fixed in a month or so as the haldex/gearbox service is nearly due,also the hesitation problem at 2000 rpm is more noticeable now so will get that looked at and also needs either a thermostat or sensor as the cooling fan runs when aircon is off and a cold engine, time to sort it all i think. Ps after parking mine up for a day or so all the lights on the dash had not come back on so there must be some sort of automatic reset perhaps hence no stalling since January.
