Took my old scooby down for an Mot today an it failed on the Lambda reading. Never had any issues on previous mot's and haven't made any changes to the car recently. The car hasn't been used for the last 7-8 months but I have been starting her up.
Reading print out below;
Has the Lambda had it? If so, how do I know which one?
Few comments online are suggesting it isn't always the Lambda causing the issue? Any help appreciated!
