Spent many hours on VW forums the past few nights, to read up about Vanessa’s intermittent smoke problem. My mechanic said it was being caused by all the crud on the heat exchangers, which was being burned off since hot air was now going through c/o of the alternator fan. He said it would eventually burn out, but I wanted to take matters into my own hands. I doused the right heat exchanger with Simple Green before dinner, but it seemed useless, so I came back with a toothbrush and some 409 degreaser – that stuff works wonders! Just a little dab and a scrub from the brush took out years of accumulated oil and grime, and I was kinda surprised it went down to the bare metal surface in some areas. I might add that twilight surgery is not very efficient, so I might do another session on a sunny day. Had I left that junk as is, there would have be no way for all that crap to burn out by itself. I’m keeping my fingers crossed, since the burning smoke made its way into the cabin through the heat vents and almost killed Peter Pan. Sayang.
