Thanks everyone for the replies. I feel quite embarrassed now .

In truth I dont reply to many posts either unless I feel I have something useful to offer which is rare.

I am finding that since I got the Pico, I have been able to get a much greater appreciation of what’s going on with many of these vehicles systems. My thinking is that if I am intrigued by what I am discovering, then other like-minded techs will find it of interest too.

Anyway, now I have re inserted my dummy I will gladly keep sticking my findings on here & maybe we will all learn some more.

George. The pictures are uploaded to the server that hosts my website. All I do is put the address in the bit at the bottom of the posting.

New Cat (genuine) is being fitted next week, so hopefully I will get time to confirm the repair & report back

Thanks once again

Dave
