Title: Gears jammed up i30 2016 Diesel
Post by: Stevie J on October 03, 2025, 17:22:49
Hi has anyone had an issue with not being able to select any gear? This has happened a couple of times, today it wouldn't go into any gear at all despite pumping the clutch a few times while trying. It's always after it's been parked a while. After turning the engine off and on a few times, it cleared and was fine, I'm worried there could be a bigger failure on the way. Fluid levels are ok and clutch doesn't slip either... Thank you in advance.

There's plenty of talk about the damper in the master cylinder being the likely culprit.

Here is an example thread on that subject, with plenty of links to others:  :link: Hyundai Clutch Damper Valve - low clutch bite point / difficult gear selection (https://i30ownersclub.com/index.php?topic=53888.0)

When I had this problem on my 2011 i30, I had the same problem and replaced the damper with a Mitsubishi part that I believe is identical. I thought it made a bit of difference, but after a while it was just as bad. When the clutch was replaced and I could see how worn it was, it was no surprise that I was having problems. Changing the damper might or might not work. I ended up replacing the damper with a solid sump drain plug that had the same thread. No damping (why is it needed?) and definitely eliminates the possibility of a leaky damper being the problem, which it wasn't.

On my 2015 with concentric clutch slave cylinder, I've only had problems when the hose connection to the slave cylinder has come loose, but then you'd end up with a puddle of hydraulic fluid under it.
