Hers a idea Stan, run a hair dryer on high heat and med heat into
your cars intake, say after the air filter, and note any changes to your {if you have one, i don't) fuel economy device with the car at idle.
Piwoslaw or Diesel Dave or anyone else if you have a fuel economy gauge and a hair dryer or as Stan suggested, run a heat safe hose from over your exhaust to your intake and note any differences
for the good or bad by preheating the air.
If I had a gauge I would be doing the test myself.
Good idea. I have a VAG-Com. Anybody know off hand if that will work?
