Thanks for the advice on how to solve the problem with the cracking noise near the dash board. There is no sign of a problem with torsional chassis cracks, loose rivets or the coil bracket.
I tightened the bolts securing the frame to chassis at the top of the leg tunnels & the bolts down the inner sides of the footwells & also the bolts on the floors of the tunnel. If anything the noise is now worse!
Is their anywhere else that I can tighten?
I am taking the M3W to the service outlet in Sydney next week for oil changes of the engine & bevel box. I will ask them to investigate.
