Any errors on a diagnostic ? Noticed from you sig that it has the limiter - any chance it could be the accelerator pedal ?I changed both brake and clutch switches to no effect on my 407, it still appears. I tried every suggestion to no avail. It would be good to get a fix for it after 3 years.
If the speed sensor was an issue wouldn't that start throwing up ABS / ESP errors as well?Nothing on diags, I tried re-installing, you name it. Changed the accelerator pedal to the switched one for limiter cut off, still no good.I gave up and lived with it. It only goes if the car stops and ignition is switched off and back on, till the next time. Tried switching off and on while the wheels were still turning but fault remains until wheels are stationary. Speed impulse sender? Not changed that.
Hope your feeling better Storeman?
