C5 Hydraulic Suspension Issues

[andyb82]

Hi everybody,

                       Once again im having issues with my 2008 C5. After having a new steering box fitted I am unable to set the correct ride height on the suspension,  the rear wheels are fine but the front keeps dropping down to its lowest point making road travel almost unbareable,. ive used the controls inside to raise and lower the suspension and this seems to be working correctly, but as soon as the engine is switched off the front end drops,  then after starting the car again the front will not correct itself to the correct height,  there is very little clearance between the front tyres and wheel arches,

 

The level of LDS fluid is correct and I have been through the sequence of loosening the filler cap to release pressure and then tightening it when its settled,  this had not made any difference to the problem...  Any help or advice on this issue would be muchly appreciated,.

 

thanks guys

Chances are the front ride height sensor or its linkage has been disturbed or broken during the rack change. Its mounted on the sub frame and linked to the antiroll bar bellow the steering rack. Most likely the link has come adrift as the sensor being damaged or unplugged would throw a fault code.

oh that doesn't sound to serious,  hopefully that's the issue..  is it difficult to locate and resolve???

  thanks for the feedback

The little link cost about £2 its not to bad to get at think you can get to it with the left wheel off and from underneath with the under tray removed.
