    Default citroen c2 clutch actuator

    Started having trouble with the 2004 C2. Sometimes after having the car in reverse, it will not select a forward gear. Initially, leaving the car running for about 2 minutes it would reset itself. This no longer seems the case. Turning the car off it will not restart (locking and unlocking with remote does not reset it straight away).
    Car will restart after about 5 - 10 minutes and things seem to reset themselves and all is OK. Will go into reverse and then into first and drive without a problem. Then will happen again next time the car is started.
    Replaced the battery yesterday, but that has not fixed the problem.
    Taking it to Southport on Thursday. The dealer thinks it may be the clutch actuator and has given me a ballpark figure of $3500 to replace.
    Before I spend that money on this C2 I would like to hear from anyone who has had a similar problem.
    And also know if there is anywhere where I could get an actuator cheaper.

    Default C2 Sensodrive

    Hi Anthony , before spending 1000s on actuators (clutch actuator all gear selector actuator) tell the dealer to put the latest software into the gearbox ECU,it might be as easy as that.

    The clutch actuator alone isn't that expensive, but the gear selection actuator could possibly be. Clutch actuators can become a little creaky in old age, but they will continue to work. It would be worth considering cleaning excess carbon from the brushes in the gear actuator stepper motors. They do have wearing brushes inside and can be dismantled. Not a DIY proposition unless you really know what you are doing and there are a number of possible things to point a finger at.

    Thanks for the replies.

    Gman - I am thinking of just having a service with the updates at the moment so the service department can look at the car's behaviour and diagnose the problem correctly and I am hoping the updates may be an easy fix. I have read via the web that ECU updates have fixed some sensodrive problems. With the closest dealer being on the Gold Coast I need to find a chance to get a day off work to get the car up to them. That may be a way down the track and in the mean time I am having my local mechanic have a look at it to see what he can determine.

    David S - Found a clutch acutator with 3 month warranty from dismantler for $1100. Do you think a transmission specialist would be able to clean the excess carbon from the brushes in the gear actuator stepper motors?

    Will keep the list updated as this develops.

    Cheers,

    You need to be clear on whether you need a clutch actuator or a gear selection actuator. New prices should be under $1K for a clutch actuator but perhaps $2K+ for a gear selection actuator. Add labour. Price them via your dealer if you wish, but remember they are two different parts. It would be very unusual to need to replace both actuators at once. You certainly wouldn't rush to pay $1,100 for a used clutch actuator.

    I think you need to take it to a dealer for diagnosis. To adjust the clutch actuator correctly, you need a setting jig/tool and I doubt the local mechanic will have one. An out of adjustment clutch actuator is more likely to give you bad changes than no changes, so you may need to look at the gear selection actuator. Removing and dismantling the two actuators would not pose much difficulty for most people, but assembling and then setting them up correctly is not a job for a DIY person or mechanic unfamiliar with Sensodrive. Of course, it may even be an internal gearbox issue and not an actuator problem.

    Edit: Check there is no corrosion on any pins in plugs associated with the actuators and ECU.

    Default Update

    Just a quick update on this C2 problem.

    Left the C2 at my local mechanic when picking up the C5 after is normal 10000km service yesterday in the hope that they would get a chance to have a look at it.

    Caught up with the owner after closing (he passed me as I was getting near the shop at 5:15, turned around and drove back to meet me at the shop).
    All was locked up and the car is still up on a hoist, so I did not see it.

    The shop owner tells me that after a lot of investigation they discovered, nearly hidden behind the fire wall, two ABS wires broken. No ABS faults were showing up on the code readers.
    After fixing the wires the car is operating (on the hoist) as it should. Going between reverse and first without any problems numerous times. If the car is turned off it starts straight away.
    Fingers crossed that when they get the car off the hoist tomorrow and road test it this will still be the case. I am also getting them to do a simple service while they have it on the hoist and a few bits off it.

    He suspect that the gearbox ECU was getting confusing messages from the ABS system ( one wheel still moving, another stopped or something to that effect) and thus shutting down until cleared via lack of current with the car turned off for 5 to 10 minutes.

    I will give another update when I have the car back.

    Default Update Two

    Thank heavens for a good local mechanic willing to listen and to take the time and care to fully investigate a problem. I know I only described the problem and the car's behaviour to the Citroen dealer over the phone, so I am not casting dispersions there. I am just very pleased I had this fixed for under $200 and that it did not need any of the actuators nor the gearbox ECU replaced.

    Picked the car up this afternoon and all is fixed, it is running extremely well and making better gear changes in both auto and manual than the good changes it was making before the problem (it did have a service as well).

    Quote from Tax Invoice: " Found Damaged Wiring Removed Inner Guard to Access, Repaired ABS Wiring, Refitted All Parts Road Tested. All OK At Time Of Road Test, Damaged Wiring Most Likely Caused By Vermin. "

    As stated in yesterday's update, it seems the ABS fault was confusing the Sensodrive.

    Cheers all.
