I am having intermittant problems with the electronic speedo on my 2013 Caterham 7 (Roadsport 170). I wonder if anyone else has seen this problem & if a solution exists.
Here is the problem: When the car is cold and just starting, the speedo works fine, then as the car warms up, like 20 miles the speedo starts to go intermittant with the needle fluctuating wildly. Eventually after several more miles the speedo zeros out and stays there. Its worse on hot days, and on cold mornings I can sometimes drive 60 miles before it goes bad.
What I tried: When the problem starts to happen, I sprayed 'Freeze-spray' (used for electronics diagnosis) onto the speedo and it started working fine again for ~ 5 miles before going intermittant again. This led me to suspect a failing chip inside the speedo. So I got a replacement speedo from Caterham, but is shows exactly the same problem.
