Hi all,

I'd like to finalize my issue here.

We changed the gearbox electrovalve and the oil as per this topic+ (this topic for AL4 electrovalves) and the videos there (very helpful) and it's all good now.

Thank you very much JAGPURR! All the best to all of you!

My 1st post here so apologies if any info that you already have.

My C3 have the same issue for a while now. I have spent countless days to make sense out it.
I wanted to express appreciation for pointing out potential problems. I will be replacing solenoid valves myself.

Thank you for excellent tutorial, effort and time spent collecting photos and videos.
I must say I have watched it many times focusing on 100% comprehension off removal and installing manual rod valve as that seems to be the most important and difficult part of it, hence the reason why I have not done it as of yet.

As my contribution to this topic I have explored suppliers for parts required. Please find list below, and I would appreciate any input if something was missed:
-2 solenoid valves
-cover gasket
-solenoid block flow and return seals, 2pc
-possible change of pressure regulator sensor (external part on the bottom) but that may have to wait due to costly part apx £70.

It does not look as difficult to replace if need to be latter on and requires no oil drain or change.

Only thing I do not have is Lexia to reset the oil counter to 0.
-3 to 4 L of original Citroen gearbox oil

I have visited local gearbox specialist in TW11 area. Cost to replace valves, seals, gasket, pressure sensor was £500 + vat
So I have compared it to parts cost form eBay supplier from tutorial.

I have also got quote from dealer including 4 L of gearbox oil at £373 which again is a bit rich
Here is the estimate

Also the have emailed me loads of pics from gearbox so someone may find it usfull. It is PDF so admin can edit as needed.
