I'm not too sure I trust all these people who say that "the missus" filld up with wrong fuel , I've done it twice - and yes I felt like a muppet. first time was coverd by insurance, second time insurance refused to cover it and Johnsons of Oxford wanted a hefty fee, never being quick to part with the hard earned I googled up on it and found a local company to do a fuel draindown for a couple of hundred, and as i suspected the dealer was on the make http://www.fuelfixer.co.uk/2012/07/petrol-in-a-diesel-lexus/ put my mind at rest

I would not rule out a choked fuel filter (After ruling out the maf), anyway good luck with it

needed a second opinion after being quoted silly money from a "stealer" for a gearbox fault, thanks google!
