Not understanding what the cause of the burning smell was coming from, I thought that it would be wise for my dealer to do the diagnosis. The dealer is pretty cool with me supplying the parts and they supply the labour (roughly 2 hours) to do the work. I'm good with simple things, but don't have a ton of tools, so I rely on them for the "heavy lifting".
