No worries, back to normal. As I said that code looks gibberish. I can only suggest you check the documentation, I suspect something is not configured correctly. Is this the first time you have used it? Just watched a video of a guy using a Honewell OBD2 scanner and it flagged up normal codes P1031 etc. as you would expect. Andy D

Yes used it many times The E/M light was on for a while showing EGR valve fault. Now it's getting due for an MOT I changed the EGR cleared the code all good for a few days, it came on again MAP sensor, changed the sensor cleared the code all good again. It came on again P0408 EGR sensor b I cleaned connection to EGR all good again now it's on again U3FFF check owners manual. Not mentioned anywhere. Thanks Sean A
