Ive noticed recently my VRs has stalled pulling away. Apart from poor clutch control the actual clutch (@145k) is showing signs of age/wear. Although it’s not slipping at the moment could this cause stalling ?

Yes, it is. Try bleeding the slave cylinder first. Really do it properly. If still stalling, do a complete clutch replacement.

Due to the miles ( 146k ) I’ve booked it in for a new clutch as I want to keep the car for a while 

Spoke to the mechanic, he changes out the DMF as matter of course, so good news
