[Vwdiesel] Ways of cooling an AAZ

[Doyt W. Echelberger]

Just an after thought to my recent long post on this thread.......

On my 1985 1.6 liter TD, I had a very similar problem that was being caused 
by a invisible rubber diverter flap about the size of a man's wallet, 
inside a metal box that was part of the passenger-side fender and right at 
the beginning of the air intake stream. The flap had come loose along one 
edge, and as the volume of intake air increased, it began to flutter and 
move so as to partially restrict the air flow.

I drove it that way for at least a year, with increasing frustration over 
the seriously reduced fuel efficiency and poor performance, before 
desperation finally caused me to pull the intake system apart from front to 
back. I found the invisible flap by reaching into all the hidden cavities 
to explore for obstructions.  I think the flap was some kind of diverter 
valve that brought in heated air from around the exhaust pipe, to help it 
run better in very cold weather. But that was years ago....and memory 
fails.  I do vividly remember how well it ran at higher speeds after I 
pulled that rubber flap out of there.....and how I kicked myself for not 
tearing it apart when the problem first showed up.

I don't even know if your Golf has similar engineering, but it is worth 
mentioning.

Oh well......
