Simple, unfortunately not when the car is a 405Grx4!!!
The speedo hasn't worked since I've had the car. It has always been my intent to get the speedo working and last weekend was the catalyst.
I had a water leak in a heater hose that ran behind the engine. To make access easy I removed the cam cover, then I could start to see the speedo drive.
On dismantling the speedo drive, the following was noted;
The speedo cable "plugs" into the ECU sensor/sender. With the sensor and speedo cable removed I could just get hold of the actual speedo drive. (The speedo cable was seized and has been replaced).
When the speedo drive had been removed from the gearbox I compared it to what had been supplied by Peugeot to the chassis number and description of the car. Not even close. I described the part to the local Peugeot dealer today - he had never seen a speedo drive like that! Can anybody in this group help??
The speedo drive looks as follows;
A steel shaft approximately 100mm long and 6mm in diameter.
15mm from the bottom of the shaft is a plastic gear with helical teeth (I assume this mates to a gear in the gearbox).At roughly 1/3 and 2/3 the way up are plastic "collars" approximately
2mm thick. These are firmly fixed to the steel shaft.The top of the shaft has a square hole to take the speedo cable.
(When fixed in the car, the top of the shaft also passes through the ECU speedo sensor.) I believe in this case the actual speed is not important it is just a go/no go sensor so that the fuel can be altered at idle and stationary.)
So, has anybody sen anything like this? Can you help my local Pug dealers out?
Best Regards
