2007 Mk2 Citroen C5 clutch pedal travel.

[falling-out-with-my-car]

Hi,
can anyone advise if my Mk2 C5 2007 exclusive has the dreaded auto adjust clutch clip please like the xantia?

I am trying to determine clutch wear by the pedal travel with the car now at 85K

how long could I expect a clutch to last (assuming it is on the original clutch) and is the pedal travel fairly accurate in determining clutch wear?

Xantia clutches lasted me about 80K but then I did a lot of towing of cars on huge 4 wheel trailers.

occasionally I get a bit of a rumble through the car on acceleration almost as though the revs are not high enough

particularly when accelerating on slip roads in third or fourth gear.

admittedly it is taking time to adjust to a six speed box I rarely get into sixth unless doing 70mph +

I always dip the clutch pedal when starting the engine is this good or bad for a dual mass flywheel?

thanks in advance

Nigel.

The clutch is hydraulic on your car and has automatic wear adjustment Nigel.

DMF... The secret is keep it smooth - don't accelerate at low speed in high gears. Use handbrake and keep it in neutral at lights and definitely no riding of or resting foot on the clutch. It is very easy to use 5th and 6th gear at relatively low speeds - as you really can't hear the engine much, but don't let the DMF do too much work as it won't last the course.

Hello Marc,

can you elaborate briefly please? how does the adjustment work?
is there any way to gauge its wear? other than a strip down?

Im thinking about having a Duck clutch fitted.

Thanks

Nigel.

On your car it should have an original LUK Clutch - and the automatic play adjustment mechanism is (8) in the diagram and the compensation springs (9).

I updated my last post above regarding some DMF advice too.

My thought about DMFs is that heat kills them - so do not hold it on the clutch any longer than absolutely necessary. Our C4 needed a new clutch at 90k as the release bearing exploded - so no sitting with the clutch down either. My 307 is on original (AFAIK) clutch and DMF at 125k.....

As Marc says the 2.0 16V HDi has a self adjusting clutch and hydraulic actuator, so pedal position will give no clue as to wear state of the clutch. I helped my mate change one of these, and it's not a lot of fun! His had done about 90k - the clutch was still in reasonable shape with plenty of wear left, but the DMF was toast - so much slop that the flywheel part was wearing the outer cover, and a great pile of metal dust fell out of it when we took it off. The original LUK clutch / DMF is not cheap - no idea how much the conversion would cost to Duck clutch - is a full new clutch kit required, or just a retrofit of a new actuator?

Thanks Marc,

That's very helpful. I do hope its a LUK and not a Valeo Ive heard a lot of bad things about Valeo DMF's
wearing out at around 25k


Richard,

its a retro-fit of a new actuator which talks to a radio control Transmitter pcb inside the gear Knob basically a switch
you flick down with your finger before manually selecting the gears.
The receiver/actuator pulls the clutch pedal down for you, there is a module mounted under the dash with 3 switchable settings
and one for your own personal driving style. this actuator can mount on top of the gearbox in some cases.

it can be switched off to go back to manual driving mode.
