Change the place your getting your fuel from. I've had this issue with BP high octane. Easy thing to start with.

OK will give it ago I got told to use shell v power

The engine should be able to cope with lower octane at a slightly reduced power level but I know my 2.2 pinks when the fuel level is very low, if the anti knock sensors are not working that would result in pinking but so does poor fuel, I drove to Stuttgart a few years ago and had half a tank as I passed through Holland so topped up to make a straight through run and it wasn't running as well as normal, arrived on fumes and put in the local 100racing V-Power you could tell the difference on restart so whatever I got in Holland I was glad it was only half a tank!
