Hi can anybody help I am currently getting a lamba bank 1 fault code cannot find any leaks and readiness test says passed on all??? If I delete it returns within a day block 32 says 1.8 in block 1 and block 2 is still at 0???? No other faults dosent seem too be any leaks although my vacume has either increased or decreased it did sit at -0.6 now sits at 0.8 any pointers would be appreciated? The lava sensor pre cat is 2 months old genuine bosh could it be the rear sensor don't really want too buy one without being sure? I did get this code before replacing sensor but seems more frequent now I am running at actuator pressure could this cause the fault as I'm not getting cat hot enough but if that were the case I shouldn't pass readiness test??
