Hi Poster,
After close examination under the dash, I think the cracking noise, which by the way sounds like the noise you sometime get if you sit down hard on a wooden chair, has got to be the ash frame moving against the body. High humidity & the noise disappears due to the wood swelling. I have sprayed the frame with a teflon aerosol. yet to check under dry conditions. Only other problem with my M3W so far has been a failed fuel pump at 500km, fortunately close to home.
