This reminds me of a few posts on some other BMW forums, where the insulation of the wires around the plastic connector that hooks up to different sensors got frayed, giving all kind of codes. One guy actually examined the wires around the connectors and noticed that the insulation will split and degrade just like the plastic cooling parts.

I just thought to throw this out there maybe this will help some people who read this post and have some "bad sensors issues".
