It was a good two years then one day.. car stalls..no codes!!!!
Hey Folks,
Hopefully i can get some input from the pro's here!!
Car stalls at lights or while driving.. even on the highway!! It just dies.. no rpms
Here's what happens
car dies
go to start it.. it cranks put it doesn't start
let it sit for 15 seconds
Start and the EPC light comes up with the RPMs at 1100 (fluctuating)
turn it off, wait 15 seconds
starts as if nothing???
On a side note: normally when i start the car i here the fuel pump going..other time like when im cracking i don't think i can here it???
Changed the Fuel filter and the Crankcase Ventilation valve.. no change.
its hard to diagnose without a Code!!
My internet search have brought the following possibilities
Fuel Pump
Fuel pump relay
MAF issues
Engine speed sensor
Mechanical vacuum pump (located to the left side on the ABS/esp module) its a round silver canister apparently - a audi worker stated that this part often brakes without error codes
Thanks in advance!

Spare made no difference.. found that the little blue check valve what not working (not able to blow through it from either side) going to replace that and see.

Re: It was a good two years - NO CODES, car stalling!!!!
Could also be a vacuum leak.
Happened on my '04 A4 1.8T Quattro, same symptoms.
Listen for hissing sound under the intake manifold.
Have you tested for any codes? (OBD II)
My Codes showed random misfire.
It was a broken vacuum T connection, right underneath the intake manifold.
Replaced the T from Canadian Tire ($3.00).
Ran perfect after that!

Had similar issues in my 97. Had to keep on the gas so it would not stall. Made it all the way back from a road trip like that. Turned out to be the MAF.

My suggestion is :
Change your fuel filter.
