Just quick update.

Engine management light off cam shaft sensors replaced. Oil changed and filter replaced.

It has now on 2 occasions refused to select reverse both times it has been cured by putting it back in neutral.

I can’t believe at 17000 miles that it would develop a gearbox fault, I know it’s ten years old but it’s hardly done anything.

Have you had it from new?

A new cam sensor is unusual for such a low mileage too.

At least you found a 'work around' by selecting neutral again to then select reverse.

Did you try the gearbox reset? Did it "click and clack" for a good minute or so?

Can you tell me what type of engine you have (there are a number of variants to the 1.4 engine)?

The engine type is the 6th,7th and 8th letters in your VIN. For example the engine in a car with the VIN beginning with VF7FCKFVE1234... is KFV.

Gearbox reset tells the sensodrive where things are. Clutch travel, gear selector positions, ETC. It's not uncommon for the sensodrive to get "confused and lost". Gearbox reset may put it back on track. Gearbox reset is in the owners manual so I assume Citroen don't expect it to cause damage. No disrespect intended, but if you are not willing to "try stuff" take it to a professional and let them sort it out.
I would recommend a Peugeot dealer...yes Peugeot...as Citroen seem to be a bunch of muppets!
I completely sympathize that you take the ultimate responsibility and it is not possible to hold us to account if things go wrong. So if you do not wish to take our advice, that's OK.
Seriously though, there isn't much you can do with the Sensodrive. The Clutch actuator causes 99% of failures and most of those failures are from salt ingress into the electrics. So the gearbox reset is the only thing the average user can try before "seeking professional help".

Whoops I may be out of my depth here...sorry.

Your car has the new "prince" engine and I am unfamiliar with that.
Also, it may have the EGS semi auto gearbox and not the sensodrive. The EGS uses hydraulics to move the clutch and gear selector.

Help! Arfur! Can you confirm if the later model C3's have the EGS or sensodrive gearboxes. Thanks.

clairebal, if you are still out there can you post your VIN?
We need to check what type of gearbox you have.
