Clutch went on our pug 106 last week. Garage in moreton quoted 323 ( a1 recovery on tarran way ). Got it done for 145 at garage on the beechwood ( md autos near beechwood social club ).
Let me know if you have any more probs with your 106. My dad did a clutch change on a 106 for £115 a few weeks back. Plus he's helped me rebuild mine twice when i've written it off He is an ex mech.
The clutch on the focus includes a concentric slave cylinder so is a bit more costly for this model guys so not going to anywhere as cheap as your 106, the parts kit costs more than that!
