Thanks for that. I replaced it with a part from Euro Carparts, not a Bosch part though. Unplugging the old MAFF or the new Maff makes no difference anyway, so I suspect there is something else wrong. I will keep checking the vacuum lines. When it failed the MOT 7-years ago I got the same code. It's been off the road ever since with occasional start ups. All I did to get it through after the long lay up, was to put Cataclean in the tank & take it for a fast test drive. The EML has been off ever since. I have only done about 15-miles in it since the MOT, as I have been sorting the auto gbox light.
