Hi there. I have a 06 doblo 1.9 multijet 120 and I seem to have an intermittent fault with the speedo. It seems to read the speed OK but the needle on the dash kind of pulses. You can't realy notice it when at low speed but as you get faster (40mph+) it becomes more pronounced. There are no warning lights on.
Could it be a sensor or something needing cleaned ?
Any hints appreciated.
Cheers
