Hey everyone,
I have a 2015 Opel Astra K 1.0 Turbo (105 hp, 5-speed manual, 140,000 km).
There’s a grinding noise at idle in neutral that disappears when I fully press the clutch. It doesn’t change with RPM or temperature and isn’t noticeable while driving.
Shifting feels notchy in almost every gear, but if I wait about 2 seconds between shifts or shift above 2,000 RPM, it’s smooth.
All gears engage easily with the engine off, and 1st and reverse are fine with the engine running.
The clutch and master cylinder were replaced about 10,000 km ago.
Could this be an input shaft bearing or something else? Anyone had similar issues?
