Hi guys, My 2011 Sigma has just passed its MOT, but I mean JUST! The guy at Kwik Fit tested the lamda maximum value for Fast Idle at 1.027 whereas the maximum allowed is 1.030 (according to his machine!). The VOSA guide says the maximum should be 1.09 so in actual fact it is well under. Has anyone else had any issues with this variance in the maximum values? Many thanks Iain
