My impression: The C6 is the best Citroen ever on normal good roads, both the very advanced suspension and low noise is important. There is also a nice soft DS-like character: Over some problem roads it will behave a litte boat-like, softly over a wave. But: The magic from the DS and CX is not there: The behaviour over deep (not sharp) holes and silent police, The feeling of "the faster, the better" and absolutely feeling different from ordinary cars are not there. The XM was in between. I think the problem is the restricted ability for suspension movement in the PSA platforms (XM/C5/C6) compared to the genuine Citroen DS/CX with much larger space for suspension movement (maybe someone have measurements ?). On this website there are lots of discussions pointing to the importance of maintenance and adjustment for the C6 (spheres, height adjustment, no play in any links etc), so it might be a nervous system. The combination of Hydractive 3+ , AMVAR and advanced multilink system should be a success formula, and the motor press was enthusiastic (and the Top Gear video) or is it too complicated for its own good .. ?. My experience started in 1980 and are DS23, CX T, XM V6 and now C6 (600 000 km in total)

I have question about height setting relevant highs. Does engine work during the seating or not?

Hello Nikola,

No need for engine, just ignition on.

Best regards,

Phil C.

2.7s absolutely stink (exhaust fumes). First thing I noticed when I brought my ‘3’ home: practically no exhaust stench. A very, very clean-burning DERV!

One of her previous MoT test advisories states, “emissions to(sic) clean to regester(sic)”.

My 3.0 Hdi has 165 000 km's and exhaust system ends /tail pipes/ still looks almost clean inside ! (but look at an Audi or VW.......)

That's really interesting and it must be down to the chemistry of the C6 system with the newer 3.0hdi C6. We also have at home a LR4 Discovery for the family with the 3.0litre diesel and it stinks almost similar on startup to the 2.7hdi C6!!
It uses SCR technology (Selective Catalytic Reduction). It is part of an emissions control system that injects the AdBlue liquid through a special catalyst into the exhaust. Funny how this newer system smells the same as the much older Citroen system.

I remember explaining the DPF to a tyre fitter as he fitted new tyres to my 2.2HDi C5 Estate, around 15 years ago. I demonstrated by wiping a clean, white cloth around the inside of the tailpipe. To his amazement, it came out clean!

compared to other hydropneumatic citroens, i found c6 ride pretty disappointing.

uhm… come on... how can it be?

Probably best if I re-phrase it - the ride is very good on smooth surfaced motorway type environment at high speed. But mid-low speed pottering around town with undulations/potholes/speed bumps, (granted they are not what C6 was designed for but you have to get to motorway from your home somehow) I found the ride harsh and uncomfortable compared to my other Cits - GSA, CX, XM and even C5.


Bit of a thread revival but this post has nailed my description of my car, am I expecting too much of my hydractive suspension around town or is there an issue with my car?

It's so hard to guage when you haven't owned a C6 from new

I'm trying to understand the cause of my cars harsh ride around town

From what I've read there is only a small amount of adjustment (in millimeters) with regards to the height setup, but it seems if the car doesn't like the information it is being sent it will set AMVAR to hard to "save itself"

What is the car looking for to trigger this "safe mode" Are we talking the case of 1mm??
