 Getting there slowly brake switch cured numerous faults,
but what im getting all the time are these faultsrelating to front static pressure sensor it comes up as one 3 faults then you can clear them and 2 faults remain
being front satic pressure sensor and reference hieghts not programmed,
Could someone tell me where these sensors are located
irc my last c6 had same issue but was at rear

 Hi there,

You'll find the pressure sensor in the front RH wheel bay after removal of the wheel and the splash shield.

The other fault indicates that for some reason the reference heights of the cars' suspension were either never set or they've somehow been deleted.

In this forums' Technical Documents section under suspension you will find descriptions on removal and refitting of the pressure sensor (may be somebody just pulled off the connector?) and on setting the reference heights. Specifically the last job needs to be done with high precision if you want your C6 to serenely glide the way it was meant to be.

PS: If your car has recently been serviced by an official Citroen garage, don't go back there but find a knowledgeable C6 workshop instead.

PS2: The battery voltage reading is just a wee bit low at 12.04 V. You may want to check your battery as well.

 i have noticed the suspension seems to float up and down a bit too much and it appears to bang and crash over bumps and potholes this is todays reading
