    I went thru this same issue last year after I purchased my car. I was told the mass air flow sensor was bad, so I spent 160.00 to buy a new one. I had it replaced and the code cleared only to drive it about 5 miles and have the same light come on and the exact same code show on the new scan. The part is not defective, yet the light continues to stay on and the Emissions Workshop indicator lets me know every time I drive my car that something is going on. I think it is a wiring issue, but not certain. Hopefully one of us can have it figured out and repaired so we can share what the true cause of the lights really are.

    I have a 2000 VW Passat GLX. The "check engine" light has been going on/off for about three years now with the verbiage "Emissions Workshop". Took it to the same dealer. "Could" be the a)throttle body - $800 b)air intake manifold $650 c) O2 sensor $200 or have the heads take off and d)clean the air injector openings $2000. They have also just re-set the code and it does go away for awhile. Seems to happen when I don't let the car warm up long enough - especially prone to happen when cold outside. I garage my car so it's not getting that cold. Am tempted to just leave it be but at the same time don't want to hurt my car. I have almost 140k miles on it. Love the car, but when things go wrong, very expensive to fix.

I would trust them but make sure it is just not in need of some kind of cleaning.

2003 VW PASSAT. Check engine light goes on and


8.5 hrs + parts sounds about right. But why would a 7 year old cars oil pump fail? They usually last a lifetime. Has there been a lubrication problem? Low oil, cheap oil, wrong oil? But then again my daughters 04 Toyota needed a valve job, head gasket and water pump recently. I'm doing 90% of work and it still cost about $2000. Her problem was bad oil!

Where is the lower MAF Sensor


The VW passat has only 1 MAF (massAirFlowSensor). If you follow the air intake, under the hood, from the top left of the grill...it goes to the air filter box. Depending on what the code says, You may need a new air filter if the sensor is not picking up enough air volume.
Follow up a bit futher and you will find some round plastic air duct, and in between these and the filter is a square MAF. It is attached to a piece of the duct, and the whole thing is replaced.
Many of these go bad because a dirty air filter will allow particles to clog it up. If you use a can of electrical cleaner on the little spring like sensor inside, you may just bring it back to life.
It is a very sensitive sensor, do not touch it with anything. A new one is around $150.
Good Luck!

Maybe you magnetic wheel sensors are contaminated or need replacing, that's what sends the data to the ECM. A faulty wiring could also cause sporadic occurrences when a problem acts up.

2003 VW Passat "Oil Press, Turn Off Engine" and "STOP" Light


I would check the oil pressure sensor and the oil pump itself. You can take the sensor out and use a mechanical gauge to check the oil pressure. If the oil pressure is within specs, you need a new sensor, if not, you need a new pump.

EPS and Check engine light on 2004 Volkswagen Passat Turbo


I note that you posted your question 14 Feb 09, so happy belated Valentine's Day! Anyway, I own a 2004 VW Passat 1.8 and am currently facing the same problem (EPC light and check engine light on) and subsequently, I coded it out, which was P0322. I took my other vehicle (more reliable) into the VW dealership in Olympia Washington. I was going to replace the EPC sensor, which typically handles what is sent to the car's brain, telling it how much gas it needs to run. However, the technicians at the dealership told me to code it out before investing any money without knowing exactly what should be replaced.

I took the code and determined the "crank sensor" was defective. If you call around, you should be quoted anywhere between $48 and $90 respectfully. If your VW was lurching like it was missing for a split second at a usual speed, or died at stops, then I would say you were experiencing the same problem I was having. Hopefully, this will fix your problem? The part is pretty inexpensive, but I think what VW charges to replace the sensor, is highway robbery. Anyone in your family mechanically inclined? Good luck!
