You're right! it's not one of the indicators that light up when the car does it's startup test. My car is a 2006 Jetta and the light is next to the center bolt (for lack of a better word) that holds the needle on the RPM dial. Anyway I always hear this stretching noise at startup andsometimes this kind of pumping noise while I drive after coming from a cold start.

Hello, my girlfriend's 2006 Rabbit (2.5 - manual) is having the same problem (she sometimes hears a knocking and it won't restart after re-fueling until she pumps the gas).
 
Did you ever find out what was causing your problem?

#43 of 45 strange gurgling noise in air intake of 2001 v20 jetta by parner

Jan 14, 2012 (2:34 pm)

my daughter has a 2001 v20 turbo jetta that when idleing makes a strange gurgling noise in the air-intake. It was fitted with a K&N intake before we bought it. I replace some of the air lines that come from the top end of the engine. when i got the broken pieces out of the fitting noticed a pasty, oilly, and watery. Tried to blow all of the water out with compressor, but air-intake sounds like it is sucking water through a straw with a hole in it.
 
any help would be greatly appreciated

I am not so sure that VW offered a 2.0L turbocharged engine in 2001. I believe it was a 1.8L turbo. (Actually an Audi engine)
 
The gurgling you hear may be oil sitting in the base of the intercooler. The oil usually gets there from leaking oil-seal on the turbocharger. A small amount of oil in the intercooler is normal.
 
VWs have a "Cold-Air-Intake" from the factory and adding something else is just a waste of money. The factory air-filter is MORE than adequate for the engine. Especially a turbocharged engine where the air is FORCED into the engine.
 
K&N intake filters on a VW are bad news. The oil from the filter is KNOWN to contaminate the MAF (Mass AirFlow) sensor. You have been warned.
(Youngsters add CAI to turbocharged engine so they can hear the whine of the compressor.)

My daughter just bought a 2007 Jetta and we noticed this noise during the test drive. The (Toyota) dealer sounded sure it was the flap motor (he called it the blender, it "blends" the hot/cold air to the selected temperature). He said the part was maybe $400 but it was 7-8 hours of labor due to taking off the whole dash. He offered to replace it for 50% off labor if it keeps giving her problems, for now she's living with it although she's reporting it happens not just at startup but when she puts it in reverse and sometimes simply while driving.
