I'm having problems w/ my 97 passat,it runs for about 20/30 minutes and dies on me,it just dies. try to starts ,the engine turns but nothing. Change the coil and still the same after I let it cool off for about 10/20 minutes it starts again and goes for another 20/30 minutes . When it first happened it was once or twice a day now it;s every half hour or so .My son drove it till he ran out of gas and after thats when it started to happen. Can anyone help me I appreciate it. Thanks..

When it won't start can you hear the fuel pump running for a couple of seconds when you turn the key to on?

Oh!, I was thinking of some kind of relay . or some type of sensor that have anything to do with the temperature I also mix the anti-freeze same color . ( not much )

I hear no noise coming from the gas pump when I'm having this problem ..

On TDI Passat, relay 109 usually go bad.

It's like 30$ at the stealership, so try it out (if you have one, it's black and has "109" in white on it).

Good luck!

Sorry for the delay but I could not hear the fuel pump working even if when I'm not having this problem , I can hear only when the engine is running..Thanks for your reply...

Next time it is running properly, turn it off then turn the key back to on (not starting) & note the hum ou hear for a couple of seconds. That is the fuel pump hum I am referring to. Yes, I am suspecting the ECM power supply relay (very common to die on Diesels known as relay 109). On you car it is in position #3, top row of main relay panel third from the left. Next time it dies note if this relay gets hot.

Thanks Boschmann, I realy appreciate your help. I tried to hear and no hum . Do you think it could be something wrong w/ the fuel pump?

I try not to go by that printed number on the top, position #3 is the ECM power supply (top row, third from the left). After running for a while & when the car dies, that is when you need to feel the relay. You can try tapping it & see if it restarts. Also that is when you need to listen for the fuel pump when you turn the key to on.

I have the old relay here # 191 941 595....
>PA66-GF30< .. could it be it. Sould I get a new one?

boschmann · #13 11-04-2004, 08:46 AM

When I look up that number it comes back as an auxillary light relay (from a Vanagon). The original relay in position #3 should have been black & had the #109 printed in white on the top. It sounds like someone switched it with what thy had available. Get a new relay from the dealer, it has been redesigned & is part number 1J0 906 381A. They are only about $18.

Went to VW dealer and this # is not the same, terminals are different from the # I gave you. So I took the car to Auto-zone and they check came up w/ code # 0411 (secondary air injector malfunction ) and 0725 ( engine speed sensor circuit ) .I have no idea what they are or what to look for or where . Can you help me ? Thank you...

boschmann · #15 11-07-2004, 05:08 PM

I used the dealer system to look up that number, maybe I did something wrong. Just ask you dealer to look up which position your ECM power supply relay is in and which relay is the correct part number. As for the codes, the 411 won't cause your symptom but the 725 sure could. The SAI code means the SAI pump is working but the air is not getting into the engine (at least the O2 sensor can't tell the difference). Usually caused by bad vacuum or pressure hoses between the pump, valve & engine. The SAI pump is the large plastic motor/pump in front of the engine, beind the radiator. The 1" corrugated hose from the air filter housing goes to it. The 725 code could be the stalling culprit. The sensor is located on the frontside of the engine just to the left (of car) of the oil filter housing. It is well hidden, right where the engine & trnsmission meet, near the flywheel area (that is what it is sensing). It has a short harness that comes off it & goes to a connector. It has three wires. Unfortunately I don't know of foolproof test for it & since it seems intermittent you probably wont be able to catch it acting up. Based on that code coming up I would replace it. If you would still look up that relay as I'd like to know where my info is wrong.
