So after trying the Berlingo forum and having no joy I thought it's worth a punt at testing the knowledge of fellow trials enthusiasts.
I've recently purchased a Citroen Berlingo with a faulty speedometer and it's really starting to get on my last nerve.
Symptoms are: Clocks won't register any speed or milage. The speedo moves when the ignition is turned on and does a little test but when driving just sits at 0mph
So far I have located the speedo drive sensor and replaced it for a new one (although the box was damaged and it was the last in stock from Euro so maywell have been a duff one) and still not had any luck.
I took the car to an auto electrician who plugged it in on a Bosch computer but didn't find a relevant fault code, but said it's common for the drive gear inside the gearbox to snap and not spin the sensor best way to check was to take out the sensor rotate the wheels and see if the cog was moving, I did this and that cog seemed to be moving fine (video to hand if needed)
The electrician then said if I plug the speed sensor in and attach the other end to a drill the speedo should move and the drill would simulate a moving vehicle but the clocks still didn't register anything.
Feel like I'm banging my head against a brick wall now any help is much appreciated.
