Hi,
I had my Pluriel misbehave the other weekend. Three beeps and the snowflake of doom appeared and the car wouldn’t start. Then it did restart but broke down with the same symptoms. I reset everything on a C3 that I would find and after 6 hours we made it back home. I have since slid back the rubber boot on the actuator and sprayed firstly WD40 into the actuator and followed this after a whole weekend with lithium grease. Now the car shifts better than ever and it’s yet to break down and show me the snowflake again. Now I realise that I would be the luckiest guy in the world if this really fixes the problem but thought i’d Share just in case anyone was experiencing the same issues. My actuator was noisy shifting gears before and is noticeably quieter afterwards. Perhaps it was just sticking in or out of gear. I will let you know whether the car behaves over the next few weeks

Did that on wife#s car when it was noisy & wouldn't shift properly. Seemed to fix it! I did use spray grease though!

A few comments on a post on YouTube also suggesting that this might work in some situations, worth trying if you are having problems with the gearbox or snowflake [ since it will cost less than $10 ]

I did this for ages, and it seemed to work for ages, but last year the whole thing just gave up the ghost so in the end we had to change the CLUTCH. Yes, i know why on earth would that wear out in a semi-auto car? Anyway, I saw the old clutch plate and it was worn down to the rivets on one side at least.
New clutch in last summer, driven it for a year now, snowflake has gone away.
Was not cheap!! €900!

The Sensodrive gearbox is just the same as any other manual gearbox except the work of changing gears and operating the clutch is done by actuators. So the clutch will wear out just the same.
