Hi i have a 2003 2.2di with 75 k miles, i have owned the car for 5 years and towed a caravan for the whole time, it has always towed no problem. This year i have noticed a 'pinking' noise when accelarating under load when towing and also solo. The noise is only between 2000rpm and 2500rpm after this it goes away, it also seems to black smoke more when 'pinking'. No noise is apparant when stood still with engine reving. There is also no power loss when pinking, i have recently done 2000miles in France and serviced it before hand and added engine additive but noise is still there and getting worse since earlier this year.

Any help would be greatly appreciated

Thanks herald.
