noticed my engine light was on today lit up orange, wasn't on before service few weeks ago. Read it with my code reader and it said one fault one code, but not sure if can read the code it said "Pere:00". I've booked it in at Ford next thursday. I'm hoping it just a sensor lamba or one of those on the exhaust, any ideas anyone ?

full diagnostic done, pointed to the sensor before the cat, car running lean, however my mechanic is pretty confident that when they did the mot emission test that it was triggered because the car was left idling for some time and probably as the mountune kits seem to do, running lean at some point on idle hence the warning light came on, switched off now and hasn't come back on, so all good. Otherwise will be a new sensor.

yep all good no more engine light car going well.

oops took mum shopping had to pop back, left car idling for a long time while she faffed about and engine light back on. Popped upto my local tuning company today these are top guys and really know their stuff, ran a diagnostic and gave me the code P1131 and said was reading lean, probably a good idea to replace both sensors on the exhaust, really liked my car and the mountune kit too.
