Hi,

Right then... Changed the clutch 3000 miles ago and all is good however the wife was driving yesterday and she reported a "pingy" noise then another "pingy" noise coming from the foot-well few seconds later. To her surprise when she went to change gear and the pedal had disappeared! (It had actually moved up towards the dash) so there was a few frantic foot movements until she found it. It still drives and changes gear OK albeit the clutch pedal comes back too far.

So when i got home and had a look I couldn't see any obvious broken or missing parts and what appears to be the clutch balance spring (looks like a very small coil over suspension unit) is pushing the clutch pedal the wrong way. Even though it is doing its job and making the clutch lighter when pressing the pedal, when releasing the pedal it comes back to the neutral position (level with the brake pedal) but then keeps going and finally stops when it hits the dash! Its almost as though there is a physical stop missing.
When I removed the balance spring the pedal sat at the correct position and yes you can still change gear although the clutch becomes heavier.

Could it be the clutch master cylinder returning too far or something more sinister!
Your help and suggestions are gratefully received

Many thanks...

those master cylinders and slaves only seem to do around 70.000 miles ish when used around town a lot ie more use, also if replace one then the other wont be far off gone as well,, ie replace pair together and flush out old fluid in case of any rubber debris etc is best way forward one lot of labour to bleed the system and also the slave is a easy to replace as on outside of gearbox unlike some that are concentric and in side the bell housing and means gearbox out lol.. guess bmw could only get away with a few very stupid designs on one car i guess lol

So as it turns out it was the push rod on the master cylinder. The clip that held it in place had disintegrated thus allowing the rod to be pulled out of the master cylinder when the clutch was released. I spent a few hours growing extra joints and longer fingers and changed the master cylinder and hay presto back normal.

Whilst it was up in the air I rotated the wheels and tyres(fronts where a little low on tread, new tyres on the way) and put the pressures up to where they should be. Took it out last night and 15mins in to the journey it puts the red tyre warning light up on the dash! Stop, get out, walk round expecting a flat but no they are all still perfectly inflated... Oh goody, more fun on the horizon!
Any way thanks for your input regarding the clutch master.

You need to reset the TPM. Press and hold the button under the handbrake for about ten seconds until the light on the dash comes on. Now drive for a short while and it willset the system and extinguish the light.
