Car stalls and dies in motion

2758 Views 14 Replies 6 Participants Last post by  ylwagon
Continuing with the saga, I started the car (1.8T AWM) this morning and less than a .5 mile it started stalling. A mile later it went off and the red battery light was on. I restarted it and the problem of stalling continues.

Is this a dying battery/alternator problem or the fuel pump? Any advice as where I should start? Thanks.

P.S. No CEL and no fault code at all.

I'm more late, but this is all pointing to the MAF sensor. It's failing on you. With your baby on, remove the MAF senor; If nothing happenings then there's your problem. Cleaning it probably damaged the tiny wire that monitors the air flow.
An inexpensive part. Should cost around 20$
I think that you mean remove the MAF sensor's connector, not the whole sensor! And smac4th is correct about the type of flow sensor, I think. My old '96 A4 did indeed have the tiny thermistors instead of thin film version.
someone wrote that when you clean K&N air filter and you spray a bit too much oil on it, that extra oil could cover the surface of the MAF sensor and causing low/high signals. After a while when the oil evaporates from the engine heat, the sensor functions again.
This situation overlaps with what I did. I cleaned the K&N filter and actually sprayed too much oil on its sides. Exactly after that I got the MAF issues.
OK, now we're getting somewhere. If you still have the original air box and intake duct, put it back on with a new, clean pleated paper filter. The intake air will be cooler/denser, cleaner, the MAF won't get contaminated, so the car will run properly and have more power. And except for the oil problem, same goes for the pod filter.
