406 Speedo Fault
I have a problem with the Sagem speedo in my 406 coupe in that it only works intermittently. I have also noticed that the car seems to drive differently when it isn't working in that it lurches. Does anyone have any idea what's going on?.
there may be a fault in the ECU memory because its loosing road speed info,you wont always get a fault code though,even if it comes up with a speed sensor fault it doesent neccisarily mean its the sensor thats at fault,it may be the wiring,the fault code just means there is a loss of information from it.my guess is a faulty sensor though
