Interesting… our car has a similar fault…
Wife rang me to say she couldn’t get 1st & had people beeping her after getting out of Liverpool in traffic.
She got home and it felt a little stiffer than normal perhaps but I usually drive hire cars so not that familar.
Defiantly easier with the engine off though which points to clutch or hydraulics not cables.
Drove it today and couldn’t find any fault.
Took it to the garage I’m booked in for service & MOT on Friday, told them of the issues and asked them to look at it.
Replacing the clutch slave cylinder and all the pipes I’m guessing is a couple of hours labour? Removing the battery and bits to get at the slave cylinder is 15 mins, then 90 to change and 15 to rebuild?
Then the part at £125 approx, so a £250ish bill?
The biggest PITA on this job is that the slave has an alloy sleeve at the other end, which is the female end of quick-detachable system. The male end is on the pipework connected to the master cylinder.
The two pieces connect inboard of the wheel arch, so get covered in spray, salt and the like and corrode together, so the "quick detach" becomes unachievable, and frequently the male bit swells up and splits the female sleeve.
Anyhow, if they come apart okay then replacing the slave is probably a 30 minutes job. Slave is not too dear if you buy a LUK (the OE manufacturer) one on eBay.
If the two connectors don't come apart (the joint is like a plumbing speed-fitting; you press in a plastic sleeve that disengages some metal prongs, so the male end can slide out) then you can either;
a) Replace the male connector, which means a new pipe and a new master cylinder.
Some people dismantle the new m/cylinder and just use the pipe with the connector, onto their existing m/cylinder. The difficulty of replacing the master cylinder is trivial though, so it's not worth going to all this trouble and then keeping the old m/cylinder, in my opinion. The biggest impact is additional cost, since the m/cylinder, pipe and connector only come as a single "part".. . at £150 or more, depending where you buy it. Replacing the m/cylinder and pipe etc. only takes 20 minutes.
b) Cut off both connectors and attach plumbing fittings to the pipes. This deletes the connector, which contains a damper valve and isn't my cup of tea compared to doing it properly... especially if you bought a new slave with a shiny new female on it... but if you're a plumber and/or skint then this is a cheap piece of bodgery that apparently works okay.
Also bleed the system... it's a lot easier with the battery tray removed and that gives you great access to detach the cables, which you can pack with Lithium grease while you're there.. so it's probably worth the slight extra effort.
