After a mad dash over to Lancaster the other day, The Friday before my old man passed, i was calming down to the usual 30mph when the Lambda light came on

It didnt bother me at first as i though hey ho pop the bonnet and use the Self Diagnostic unit to reset it

EH NO !!!!!!!!!!!

Got home and realised i couldnt as it was the OBD II port instead

Is there a way of resetting it without going into the expense of a garage visit ?

Sorry if this is an old question, i have used the SEARCH facility but i cant find anything, probably not looking really

Cheers guys
