My speedo has stopped working (the mileage is still clocking up though). It was suggested that the speedometer transducer needed replacement, so I bought a new one. Despite a search by me, 2 proper mechanics & the parts guy from the main dealer, and a print out of the diagram of where it should be, none of us can find where it goes! I'm relying on satnav to avoid the fines, so any help would be very much appreciated.
