I have an '05 2.0JTS 5 speed done a poultry 59000km - that's about 40000miles to you lot.
It pinks a little on med throttle and a very small amount on heavy throttle. But....here's the thing..... it doesn't happen (or not that I can hear) when the weather is cooler and/or raining.
Hot dry days (which we have been having a few of lately - you know, mid 30s etc
) are when this becomes evident. Not so much when driving around town etc but when climbing the hill to my home it really shows up.
Where to start? Last time it was scanned a downstream O2 sensor was supposedly out of spec but my Alfa specialists reset all and all seemed ok.
Any ideas where to go next folks?
