Citroen XM Forum

Sorry... was getting excited then..

yea I done the same when I though I had the other XM sorted only to find problems with the turbo and abs, which still needs to be work on

Whats not working the Boost Guage on the dash?

Theres only a single feed to the boost guage from the sensor on the battery box, though the sensor could be at fault. I assume you have swapped sensors across from one car to the other??

yes done that, still the same

Break in a wire from the Sensor to the dash then is my guess..

Im going to get ready to go out, but I can tell you where to do some pin to pin checks with a multi meter later on if you want and are handy with a Multi meter ...

Hang on for the dash loom under the dash board, I might still need it....

lol i will keep the loom back just in case for you, not used a multimeter in years and the one i got needs replacing (years ago), could be a break in the wire

French wire copper has a tendency to rot out INSIDE the covering and break..

Despite your abs light on in the ther car have you actually done an emergency brake test to see if the abs actually still works with the light on or not.. because that does also happen too...

The abs light can be on but abs STILL works. Got this on my green sei v6 12v. ...

I have heard about the copper wire, believe it or not it as German copper origins, as for the emergency brake test the car as no tax or mot so cant take it out on the road

Ah.. thats a bugger then..

that it is
