I've got a 1.3 Ryder, and there's a really annoying noise, but only sometimes......
It seems to be everytime I ease off the accelorator it just makes this noise like something is spinning and grinding on something. It's really loud sometimes (seems louder at high revs, when I ease off and I'm in a lower gear than I perhaps should be) and quieter if I'm in a high gear.
The noise goes as soon as I 1) accelorate or 2) put the clutch down.
I'm pretty sure it's something to do with the gearbox / clutch but I don't know enough about it to diagnose, and I can't get under the car to listen to it, as it only happens when the cars moving!
