i started a thread a month ago about my vcu getting hot, after 50 miles or so it was so hot i could not keep my hand on it. I was also getting a droning noise now ans again. Removed props and drove home another 200 miles and still got the noise.Took it to a fwd independent who checked it out and found brake caliper seized, this was repaired and i also got new tyres. I then thought i would drive for a while to check for noise, after doing about 100 miles all seems good. So thinking do i buy a new vcu while its all off or stick the old one on and see if it was the tyres that made it hot.
