As ever, appreciate the offer Frank.
I'll be sure to be making a shopping list as I go, with the current situation I think I'll be doing more work at home on the Y10 so hope to progress a little bit quicker than anticipated.
Took the airbox flap control out tonight to see if I could come up with a repair.
The unit works just like a wax thermostat, a heat gun warmed it up nicely to check the movement was OK so just needed to figure out a way to make the pin to locate into the linkage.
A thick split pin seemed a good solution, relatively easy to shape but still stiff enough to do the job.
