Mine does not pitch or roll either and I am not sure it has been done. I am with you and I am leaving it alone (57 plate)

Mine is supposed to be up to date but the rebound damping at the front is very light. As a consequence there is a loud whack when the front suspesion "tops out" at full extension e.g if there is a dip in the road or a speed hump is take too fast.

Lads,

Having read this forum on suspension pitching I had noticed that the 06 car appeared to suffer from it whereas the 07 car did not. In fact my wife was driving behind me on the motorway one day and told me that she could clearly see the car rocking gently from front to back.

So finally I booked it in for suspension update in Sur Le Pont last Friday. And I have to say what a difference!! The car feels so much better. Definitely recommend it.

Regards,

Phil C.

Yes, I have commented on this update before. i had mine done in September and it really does make a difference. I always ride in sports mode anyway but there was a noticeable difference there too. It feels more solid.

Hi all, picking up my 2009 (registered) C6 today and will ask about this as I did notice a little wobble when driving it on test last Sunday. Thought that I may not be used to it is all. Where's the best place to check if this has been done?

Take it to Citroen. That's what I did and they simply applied the update. Its a quick process. My suspension has been bang on ever since.

I have endured my pitching suspension, with a side to side wobble since buying my car last may, have had it checked at two main dealers and had a software upgrade and even endured a drive round with a 'technician' who announced that all C6 behaved this way. I accepted that they knew better than me, but still was not convinced.
I eventially, last week, visited B&L, they bounced the front up and down "one of your front spheres has collapsed" so I ordered two from suplex and have just had B&L fit them, change the transmission oil and fit new rear pads, at 32,000 miles car is transformed. No main dealers again for me! Original sphere insert had totally collapsed. I suppose that the secondary spheres supplied an ammount of compliance and the LDS pumped up the car to the correct ride hight. At least with conventional steel spings it is pretty obvious when you have a broken spring

Was it one of the main strut spheres?

Front drivers side. I guess I was lucky the strut did not go through the bonnet.
But most of my mileage is up and down the motorway and in that situation the system gives the immpression of normal suspension. the swaying was really pronounced when driving over indivdual road humps, this pitched the car from side to side

If you suspect a problem with hard suspension, I find a useful way of testing the corner spheres is to drive slowly over a speed ramp at an angle. You can then compare the reaction of each corner and even detect if there's imbalance on each side. The steeper the ramp the better.

I had my Quattroporte in Bill McGraths yesterday. They gave me a lovely tour of the exotic machinery under their care; £100,000 Mistrals being rebuilt. Looking at the Citroën era Khamsins we got to talking about Citroëns. Andy, the owner, told me he had the two lads from B&L visit him a few days ago. It seems they collaborate on older Citroëns; McGraths supplied some hard to come by parts to B&L.

Andy was full of praise for them. If I have another Citroën they would be my choice for indie.

Just to change the subject, a friend of mine recently bought an ex demonstrator Quattroporte, a week later he had the front nearside taken off by a skip lorry, whist waiting to exit a underground garage. It was repaired, but took the rightoff value and bought a year old Panamera, which apart from the looks, he feels is a far superior car, especially for his daily commute into Central London. I understand that B&L will tackle Massers, after all after Citroen took over Maserati, they used the 2.5 V6 in the SM. I drove a Bora with the Ciroen Upgrades and certainly felt that their tweeking did little to improve the original

But isn't that the clincher? How can he live with such a dog's dinner of a car I seriously considered the Lexus LS460, which on every measurable level is a better car than the QP, but I couldn't park such an ugly jelly mould in my garage!

It's a shame the Citroën/Maserati marriage was given more time to bear fruit. Citroën were certainly lacking in the engine department - the DS engines date back to 1935. Of all the classic Masers it's the ones with LHM that I love: Meraks, Khamsins.

Ow! Michael, in 1934 the Tractions were in the forefront of engine design, it's only that the flat six for the DS had cooling problems that caused Javel to go back to the 20 year old design.

If Puiseux had had more faith in 1952, Citroen would have had a world beater of an engine- which means that they would never have had to buy Maserati....discuss!

I was not aware of a flat 6 was the GS engine 2/3 of this, that engine was a real belter. I remember upsetting a number of BMW drivers in an Ami Super, a early Q car. A friend of mine had to have his con rods remetaled in his light 15, shells still had not been adopted
