Clutch pedal click and crunchy gear change

searley86 · 12-04-2023, 08:50 AM

Hi all,
I have a ‘17 M2 with 45k on it. It’s always had slightly crunchy gear changes, but I was told my a mechanic (and some post on forums) that it’s not an issue.
Recently my clutch pedal has developed a click which I can feel in my foot. I believe it’s right at the top, between the bite and clutch resting point are. Gear changes have felt a bit more clunky, sometimes having to slow down as it feels the clutch hasn’t fully released.
From some googling I feel it could be the clutch master cylinder, but would love other ideas/input on things to check myself before I take it to the shop.

‘17 with 32k and about 24 track days. I know the pedal click you’re describing. I only experience it once every 6mo so it’s a non-issue for me. It doesn’t impact anything related to gear changes. It just… clicks once in a blue moon.

Re: crunchy gear shifts

It’s time for a trans fluid flush. Did mine at 22k and changes on and off track were greatly improved. I’ll do it every 15-20k to keep everything buttery.

YMMV good luck to you.

I haven’t experienced the clutch pedal click. But the crunchy shifts are familiar to me. The 2→3 shift in particular was crunchy sometimes, whether the transmission was warm or cold. It was a sort of metallic crunch or grindy feeling. Like the previous poster indicated, a transmission fluid flush cleared it right up!

Thanks for the replies! I’ve booked it in with my shop for them to double check and do a trans flush, hopefully everything will be smooth soon.
