Driving around today (non-motorway) and the light has reappeared, half expected it would.
I think the easy thing to do is to go back to stage 1, will be asking for my money back.
Would've been interesting to find out the cause/problem but it would involve too much faffing around.
worth noting that revo and revo agents map the cars at inters, given three cars have same issue would be interesting to see if there is any correlation between who flashed the code, you'd like to think they keep records and an audit trail so they can ascertain if their is a common theme
given APD have been mentioned i wonder if they flashed mandy's car?
APD were there at Inters helping flash the cars. It was Carl who done mine, he did ask me what fuel I was running on, what exhaust system I had, he tried to look under the bonnet but my bonnet wouldn't open so couldn't. I told him it was all stock though.
