It just seems to be over rough ground tbh, doesn't seem to do it on idle. It appears to be in the dashboard/front of car area.When do you get the squeak and from roughly what area?:dapprove:
Get an assistant to apply handbrake and bring clutch to bite with engine on on 1st and see if you can isolate the noise. Never heard of a mount itself squeaking, although it could be the manifold hitting the heat shield, happy hunting
I had something very similar, turned out to be the engine undertray was mis-fitted and was rubbing against the subframe everytime I rocked the engine and created a squeaking noise. Also got the same noise when negotiating speed bumps etc.
