Hi everyone hope you can help, I recently bought a 2009 Doblo with the 1.9 multi jet Diesel engine and box, of course on the test drive all worked wonderfully, but just a few days later the gearbox started getting clunky and difficult getting into gear, especially reverse, not massively serious but definitely annoying! It felt like even with the pedal pushed hard into the floor, the clutch wasn’t being fully depressed and was dragging slightly. Did a bit of research and an air lock in the slave cylinder seemed a likely culprit so bit the bullet and just fitted a new slave cylinder, but now the clutch won’t disengage at all and won’t go into gear. If you start the engine in gear with clutch pedal down you can feel the clutch slipping but it’s definitely not disengaging properly. I’ve since bled the system a further hundred times or so, swapped the old and new slave cylinders back and forth, I even made up a new and longer rod that goes between the slave cylinder and the clutch lever arm, thinking this might help depress the clutch further so it disengages properly, but nothing works..!!? The car had a new clutch and flywheel fitted less than 3 years ago, it seems unlikely it’d fail after such a short time, and I’d of expected it to slip or judder, not to simply stop working altogether. All I can think of is the master cylinder isn’t working properly and perhaps not fully depressing the clutch under load..? Or perhaps the clutch has gone but it seems odd to have been working (albeit not perfectly) yesterday but broken today when all I’ve done is change the slave cylinder. Any advice would be very much appreciated, thanks....

If its similar to the multipla there could be a problem with the master cylinder,
Spring under master cylinder piston inside the master cylinder bore can fail.

The multipla than be an absolute pain to bleed fully.
