Its not a bmw but its all the same, sort off. it relates to a Vauxhall 2007 1.8 zafira b. its a hydraulic clutch. I had a new gearbox fitted a year ago. low miler. its been spot on but I now have a new issue. after a drive of about 10 miles say 60 -70 mph I have noticed the clutch pedal is a bit harder to push, not smooth like when you start it up or drive around town. now once I have slowed down or gone back in to town the cars clutch is soft again.
