Hi, i recently bought a 2006 1.2 jazz and after a couple of weeks the clutch started squeaking. It drove me crazy! I contacted the service department of my local dealer who informed me this can be a common problem with some Hondas. I booked the car in and they lubricated the clutch master cylinder which did the trick. Back to almost silent motoring again!

Okay, this lasted for 3 weeks before the squeaking started again! Again, the dealer tried lubricating the master cylinder but this only lasted for a short time. They have now replaced the master cylinder and so far...so good! All done under warranty as I bought an approved used car.
Now to get the water leak sorted out!
