Esp/asr System Faulty

[C 5 Estate]

For some months I have been getting permanent ESP/ASR System Faulty symbol on the dash board (a yellow triangle above the temperature gauge)

 

I dug out my DELPHI and it points to @C1310 Accelorometer turn meter sensor signal internal"

 

Is this the silver coloured lump beneath the ash tray at the rear of the central console?

 

The ride may have been a bit less taught but this may me my imagination.

 

Recently the back end is dropping overnight and I wondered if the two are related in some way

 

My motor is a face lift C5 2006 2 litre deisel Estate with 126126 on the clock.

 

All suggestions will be very gratefully received.

Yes, that is the accelerometer and does throw an error if its defective.

Last time I checked (2 years ago when I changed my wife's) a new one was £400....!!!!

They are quite common across a number of PSA cars, just google the part number.

My wife had a C3 and it was the same as the one I took out of my scrapped C5 so £400 saved  :)

One of the rear struts may be leaking causing the back end to drop.

Have been of air and just logged on and noted your replies.

 

When the sunny weather comes to Preston I will put the motor up on axle stands and have a look at the struts.

 

The discs/pads need attention this year so I may make a Summer project of these tasks.

 

Thanks

On the C5 Problems and Fixes section there are a few pinned topics on the brakes worth looking at.

Have just got the motor through its MOT, as recommended I changed the acceloratermeter which fixed the yellow triangle light problem.

 

Fortunately the overnight dropping of the rear suspension stopped happening a few days after my previous post and pleased to say the Garage were happy with the suspension.

 

Thanks for your advice.
