An update - it is not the usual ERG or DPF issue, but an electrical problem with the radiator fan. So they say anyway; the car is there two days already and they still don't know what the problem really is. They just keep ordering new parts and replacing things to see what will fix it.
Anyone else experience such an issue?
I am really not happy that the new car has a problem at 5000Km. You have got to be kidding me, Alfa! This is my first Alfa and we are seriously considering buying another one, but this is not a good sign.
