Pinking Problem

I have a annoying problem that seems to be mentioned quite a lot but there seems to be no straight solution. It 'pinks' a lot of the time, mainly under load but also when I start up and pull away and general acceleration. I had work done on it fairly recently, cam belt & tensioner, balance belt & tensioner, idler, and at my mechanics suggestion a new variator. That made no difference. Could it be the 'knock sensor'?
Thanks for any help you can give.

Re: Pinking Problem

Could be the knock sensor although I am sure someone that has more experience with Alfa's would correct me. Ive had over 40 cars in the years Ive been messing with them but this is my first Alfa so am still getting used to their peculiarities.

It may be worth an ECU reset. Theres plenty of threads on how to do this.

Re: Pinking Problem

A diagnostics check would confirm that if the knock sensor is the problem. It might also be the broken bracket thing that is often mentioned. Do a search.
