I have a 2005 Citroen (second one) and last Saturday had to replace the nearside bulb - what a performance - have to remove the whole battery to do that.

 

Well that went ok - and following this drove the car - and for 5 days the suspension had completely changed - It was far softer - in fact far better to drive than it every has been - In every road condition it rode better - exactly the way it should drive in my experience.

 

However it has now reverted back to how it was before I removed battery - (might be just coincidence) The ride is still ok - but not how it should be - Almost as if it is hard when it needs to be soft and soft when it needs to be harder.

 

Would love to have the suspension ride like it was a few days ago - anyone know if it is a problem with suspension???

Is your car H3 or H3+, or to put it another way, does it have a Sport button?

 

Sounds to me like it has been stuck in sport mode.

you will have disconnected the battery when you removed it to fit the bulb. by doing this you will have reset all the ecu's including the suspension ecu. if you have a intermitant fault with the suspension it may have cleared and taken a few days to re-occur and once this has happend the fault will have been stored and put you back to square one.

I think I will just have to live with it - mine is H3 so has no sport button - I think it is just one of the quirks of the suspension - I have driven hydropneumatic Citroens for the past 15 years and never had any problems at all (and this cannot be considered a fault really) - however all of them seem to have a mind of their own and decide themselves when they have a 'good ride day' or not !! I am sure we are all a little bit hypersensitive when it comes to the way they drive - afterall we probably all buy these Citroens because of the way they ride/drive.

 

My front tyres are due to be replaced as well and I know that having new tyres plus balancing and tracking done can make a huge difference to how it feels - far more marked difference to when the tyres are changed on a steel suspension.

I'd be inclined to give the height sensors/correctors a little squirt in case they are little sticky and causing the car to ride slightly high.

 

If you are sure that the height correctors aren't sticky, then it may be worth your while measuring the ride height. Slightly too high will make for harder suspension.

Hi Not sure about the suspension ECU but I have read somewhere that if you replace or disconnect the Engine ECU it will need to be 'taught' what to do, as it will go back to basic factory settings and will take a while to settle down after this, remembering this, one of the things that the C5 does is match the suspension to the driving style.

just a thought!
