I will try that, thank you. Yeah, definitely not under warranty. My google fu is weak this morning, do you have a link for the replacing? I though it was inside the transmission housing?Google says it's a known fault that many got fixed under warranty, doubt that will apply now though. From reading, it's easy to change, but an expensive part.
Couple of posts have suggested disconnecting the battery for 5 mins or so to reset stuff, may or may not have any effect, but worth a try.
