AngusL 10 Posted January 16, 2015 Hi Guys, I managed to track down the intermittent Speedo problem over the weekend. It was related to oxidized contacts in the engine bay big loom plug - I think the 42 pin connector on the rear right hand side of the cylinder head. All I have done is use wd40 and compressed air to blow it all out afterwards. Speedo now working fine. I guess age is catching up on these cars now but its not a big task to sort things out or am I being lucky. Hope this helps someone out there.. Quote Share this post Link to post Share on other sites
MZpog 10 Posted January 16, 2015 Nothing like an intermittent problem to annoy. Well done on the fix. Quote Share this post Link to post Share on other sites
AngusL 10 Posted January 26, 2015 Cleaned and reseated U1 and U2 (Instrument cluster wiring harness plugs - ref Bentley manual) Blue plugs into the fusebox and done approx. 300 miles now and speedo has remained rock solid. Looking like that's sorted it. Quote Share this post Link to post Share on other sites
