Yeah it’s all just nuts and bolts at the end of the day!!
The actuator only seems to have a threaded nut to set it so I think if I could find the tolerance or measurement online it’s not too tricky. There were no issues with the oil feed and no leaks. Gaskets were all fine except for the one between the manifold and the EGR so I replaced that one. I’m using an Ancel VD700 to read codes etc but it’s not throwing out any codes. As a side note I’ve driven 300 miles today and it’s not happened so it’s one of those intermittent things. I’ll find it at some point I guess!!
