renault clio failed mot on emissions. cat and lamba renewed but no change. using about 5 times too much fuel on tick over and 15 times the fuel under load. Any ideas, mot says lamda not switchin but its new and genuine part.
Thanks, YT.
Possibly if you can get hold of a diagnostic device (I possess a handheld one) and plug it into your diagnostic socket, it should isolate where the fault is.
Anyone know where the diagnostic socket is on my R4 - I've looked everywhere! :smile:
