What engine do you have? Petrol or diesel?

If its a 1.6 vvti T3 as in his signiture ;) and has an EGR valve its gunna be a petrol engine.

so on that note you more than likely just need to give it a clean and you will be all good again.

Thanks im on my mobile so cant see any sig.

Diesels have egr valves, vvti engines dont have egr valves as the ecu uses the vvti as a egr valve.
