I've been lurking on this list for a couple of years
now. What a group of experts!
I own a 2000 Gold TDI, the last of the German-made
models. It uses essentially no lube oil.
I'm having fits cleaning the EGR valve and manifold
and keeping them that way. Once I get the EGR valve
"unstuck", its only weeks before it starts sticking
Has anyone on the list found some sort of solvent that
will "deep clean" the crap that forms on the EGR valve?
I've tried WD-40, brake cleaner, paint stripper, and
I can't remember what else. Nothing seems to unstick
the EGR valve for more than a few weeks. I use Delvac-1
and "name brand" fuels Amoco, Shell, Mobil.
How are fouled intake manifolds cleaned?
Thanks to everyone who contributes. I hope to do so eventually.
2000 Golf TDI, 2-dr.
