[Corsa D 2006-2014] Corsa D clutch not disengaging 2008 1.3 cdti eco diesel breeze

A clutch not disengaging problem : has anyone got any suggestions?

The corsa has been to a Vauxhall garage in SE London, 4 times over 11 months, and they still haven't fixed it.

The clutch pedal drops an inch or two at its highest point over a journey (maybe within minutes), and fully depressing the clutch pedal will not disengage the clutch (i.e. you can't get it out/ or into gear without graunching: the transmission is loaded up). If you put your toes under the pedal and pull it up to the top of the travel, its fine : for a while, till it starts descending again.

This feels like a hydraulic problem to me, with air in the system.

1.The garage started with bleeding the hydraulics.

That solved nothing.

2.Next visit : "We'll change your clutch - it's worn out". (I wasn't involved then - before I was with my girlfriend). Unsurprisingly that had no effect. The clutch WAS NOT SLIPPING.

still faulty.

3.They bled it again.

Still faulty.

4.They then changed the master cylinder, and bled the hydraulics again.

Still faulty.




So far, they don't seem to believe in diagnostic procedures, in that they haven't actually identified a faulty component : just randomly changing bits. I wonder if there is a seal somewhere in the system that is letting by, that may be "notorious" for causing this problem ?

I don't feel they should be let off the hook, as they've charged a lot of money for solving a problem, and so far haven't.

If you wonder what I'm talking about, although there's a few mistakes in the voice over (the video was made in a hurry), none the less it is obvious what is happening to the pedal :

Any ideas ... ?

How do we fault find the problem ?

Thanks hive mind !

Do you know if the car was originally fitted with a dual mass flywheel and whether at some point that has been swapped for a solid flywheel? There is a difference in the casing mounts for the slave cylinder which gives different clearance between the two. The other thought is whether there any kind of internal problem in one of the hydraulic pipes that is forming a kind of one way valve, like brake flexies can do if they break down internally.

This is an interesting one. As it appears vauxhall seem to have done the initial things you would do. But not out of fault finding but more of "it usually fixes it". I am interested to see how this turns out. If it was me I would look to take it to another no vauxhall garage w8th good reviews and tell them the list of problems and see what they have to say. I've been to vauxhall a few times and I've had to correct the kids that they have hired as technicians. So it maybe better to take it to a more schooled mechanic and see there verdict as I belive your going to be hitting fob off territory now with vauxhall as they are stuck

I had the exact same problem a few years ago with a different make of car. It was caused by worn rubbers on the slave cylinder piston allowing fluid to seep past and the pedal drops a bit. A few quick pumps on the clutch pedal and everything was OK for a while. Fitting a new slave cylinder cured it.
