Make that another one with the 3.2 Q4(red).Mine also has the qtronic box.
Im in Benfleet Essex & have always had problems finding a decent local specialst in over 20 years of Alfa ownership.lol
I've had quite a stable over the years which started with a Sud back in 88.
Since then it's been 33,75,155,2x164qv's ,2x156's and now the 159.
I did have a break between 2008-2010 which forced me into Grande Punto 1.2.
So now i'm back into financial meltdown with the 159 which I only run at weekends as the Punto takes the strain in the week.
The warranty on mine expires at the end of the year so I will probably end up taking it to a local garage to change the oil & filters.
The best specialists i've found is Alfa Workshop or David Thomas Garages.
More locally try Sunnyside garage in Kemp Rd Dagenham.
