Earlier in the week I cleaned the earth point on my grande Punto 1.4 Eleganza.
I moved the clutch actuator, and it seems to have created air inside the system.

The clutch was near the bottom, but I manage to release a little air to get myself down to the garage.

The mechanic with me assisting, pumped the peddle down and him releasing the air feed. We did this three times and the peddle became stiffer.

I got home. Took the car for a spin and feel reverse grind/crunch as I engage with peddle full down. First gear I can feel some resistance (need a firmer push than previous).

Do I still have air in the system or does it require some type of electronic calibration?

Thanks
 
I cannot see you need anything more than additional bleeding,

Was it bled in position?

Maybe worth unbolting and positioning so the piston is at the low point,

You can use a cable tie to limit piston travel as you bleed
think its now sorted.

Before going to the mechanic, I pushed the piston (retract into body). On the drive down it felt much better, so the piston inside the slave cylinder may have been a little sticky?


For bleeding, we did an additional 3 releases.
1) Pumped 3 times, then pedal down. As he release I feel my peddle drop about 1cm.
2) Pumped again, then peddle down. Release seem to drop around another 1cm
3) 3rd try. Pumped pedal slowly about 5 times. Peddle down. As he released the peddle felt like 5mm drop.

I think he expelled all (most) of the air now.

Drives as good as before, or better.
Previously I always felt 1st was loose; Sometimes its a firm engagement, and other times slips straight in. Now its firm like driving a new hire car. I always put it down to stretch cables as the car gets older.

Hope this info helps anyone in the same situation in the future.
Good to have a mechanic, however its do-able with someone pumping the pedal. One guy wanted £80 for a 10min job. :eek:
