Still not 100% wafting?

[aeroboy64]

I have posted all my problems with my c5 x7 exclusive 2.0 hdi auto elsewhere so a quick recap.new rear spheres fitted/pump replaced as old one was dying and did'nt have enough oomph to raise/lower car.
As soon as the pump was fitted it drove smoothly but a little bit bouncy and the front height seemed a bit high so but car went up and down when opening doors/boot so had the height adjuster adjusted and now LOOKS right but the waftiness seems to have gone and seems a bit harsh even going slow over small speed bumps?Would it matter that the front looked a little bit high (it is 5cm from top of tyre to wheelarch front and rear)
Looking at other non-citroen car they all seem to have a bigger gap?
Should i just bite the bullet and get my mechanic to raise it a little bit till i get the comfort back?

If it's really annoying you, and you don't feel right driving it - it will niggle you forever. Considering what you have spent already in an attempt to rectify the suspension issue - I would bite the bullet and take it to a main dealer, explain thoroughly what you have already done on it, and then get them to do a diagnostic on their kit. The reason I think it may be worth a diagnostic session with them, is that generally - and make sure you ask them to do this - they will automatically check for any software updates to your BSI and possibly any other ECU than needs it.

Incidentally, you said you replaced the rear spheres, what about the fronts? I'll assume all new LDS after you replaced the pump and that it's been flushed?

The front spheres were replaced by previous owner new fluid was used after pump fitted,The car bounces when you press down on bonnet/boot but it seems to missing the x-factor,not really wanting to trust a main dealer after my previous experience with them but having someone with LEXIA just to fine tune the heights sounds like it may be worth a shot.Thanks for the speedy reply but i don't really want to throw anymore money at it at the moment?

[GiveMeABreak]

I understand completely. I take it you've read all the info on calculating the values to enter the data into Lexia then? Unfortunately it's not as simple as just bunging a value in - you have to do the Isaac Newton bit first then this gets translated into values for the heights. I few of us have compared reference heights, each slightly different, but haven't had the need to go any further as I consider my car's ride to be generally ok, although it does depend on what day of the week it is sometimes! Some days smooth as treacle, others a bit bumpy - like it is too firm over small bumps at slow crawling speed. I just put it down to being a 'live' system where the information to adjust the ride is constantly being updated and it just has a 'bad' day on occasions. Occasionally, I have done a BSI reset to clear all the values and then it starts on it's learning curve again.

About 6 mths ago my dad bought a 2 yr old volvo s80 b3 with leather/sat nav and all the whistles and when i went out in it to say it was smooth/fast/quiet would be an understatement?
So fast forward to yesterday and he gave me a lift home (bearing in mind i've now got used to the c5 magic carpet ride after 6 mths) and f*** me it was noisy and picked up every imperfection in the road through the suspension it actually felt as if the suspension was borked!!!!! just goes to show how good the c5's suspension is at ironing out big & small irregularities that are english roads.
Seeing as his car was about 10k more when new than mine the only trouble now is would i ever go back to a "normal" car?

[GiveMeABreak]

That's the thing - it's only when you get into other people's vehicles (non-Hydrompneumatic / Hydractive) that you realise how comfortable your own actually is. I think it's only when you spend so much time in your own car that you can pick up the times when the car is having a 'puddy' with the ride - you just get to 'feel' when it's working great and when it's having a bad day!

As for going back to a 'normal' car, we won't have much choice on the matter in future unfortunately, now that the Hydractive systems are being fully phased out..

Did'nt rolls royce and mercedes have the same suspension set-up or similar (not that i could afford either).

[GiveMeABreak]

Citroen did licence their Hydropneumatic technology to Rolls Royce years ago and was used in a lot of their cars. Mercedes have an an air suspension system (airmatic is one of them) - but you'll be glad you don't have one, especially if you have to replace the suspension strut - check this out!:

I drove an XM last years after two or three years of not having one and the ride felt superb, either that one rode better than any I have ever had or my blood sugar level was particularly good that day.

I spent a couple of trips in the back of a 2012 civic, mainly to kent and back and that felt good until you hit rougher roads where it was agony. In constrast even my Xantia on an iffy day is far smoother, it just seems to get caught out by potholes that normal cars aren't affected by (like drains!)

Citroen suspension - one of the best-kept secrets that most of the population never discovered. And whose fault was that?

[myglaren]

I know it is only a circus trick but I find that 'exercising' the suspension while waiting at traffic lights can have quite an effect on the people in adjacent and following cars.
If only they knew the real advantages of Citroen suspension.

[Peter.N.]

If you want really comfortable suspension fit an accumulator sphere at each corner, you won't feel a thing - especially if you try to corner to fast.

Sounds like ideal toy for providing a bit of entertainment at a rally. Ploughed fields and eggs come to mind...

I tried it on off side side of my XM then drove along the forest track we use to reach the road, it was amazing, just how we all imagine hydropnumatics to ride only they don't, except possibly the DS. Unbelievably you couldn't feel any shock from the suspension on that side, it literally did float. I would be quite happy to drive it like that on the road if it was legal.
