I expect we will see a new fault code on our scanners

P01E10 - You plonker, you put the wrong fuel in

On a more serious note, the likes of Snap-on are working hard in Brazil on these sort of problems because of all the Bio fuel types their vehicles run on out there, they may become the masters of tech info for faults arising from E10, many Brazilian vehicles throw up a different set of codes to ours

We may get a whole new industry spring up for "E10 Re-maping" to help overcome some of the problems
