Citroen XM Forum

I need another speedometer interface box, the 9 - pin black box found under the dashboard above the driver's ankle.

Anybody have one for sale?

The Peugeot part is the same and the Pug part number is: 1929sj. Not sure if the Citroen part number is the same. It is used on Peugeot 406 Coupe, Petrol Xantias and XMs also probably the Peugeot 605.

Looks like this


Any Petrol XM with trip computer would have this.

I don't know if I have one but why do you need one. Failing speedometer is normally a plug issue underneath the clock.

Series 1 speedo's are mechanical. His fuel computer isn't working.

Graeme's problem is speed sensor data not reaching the suspension ECU and the trip computer/RH display. Speedometer (mechanical) is ok.

Yup that's pretty much right. Still working on it and just fired a brand new Bosch idle speed controller so I'm excited to see how it runs tomorrow morning
