I have the same problem - drivers side rear footwell fills up with water. Cause does not appear to be battery drain or pollen filter housing. What do you mean by engine housing module, and how much did it cost?
 
thx.

i have this same problem - a drain needs to be cleared- there is a recall that you have to do - i set up appt to ge mine done in conjunction with another issue that might involve ignitor coils or MAF -
 
for leak i know pollen filter has to be changed b/c of spore build up and leak can get into a manifold area around wheel

#15 of 62 What is the normal high temp for a turbo by mechanhic

Oct 08, 2007 (1:29 pm)

My 99 Passat (1.8L) has a new turbocharger and I have test driven it for 3-4 miles and stopped back to the garage. While it was still running to "cool down" I popped the hood and the tubocharger itself was glowing pretty good. Does anyone know what an acceptable temperature should be? If it's too hot, what could be the problem? I tested the oil supply line and the coolant supply line. Both show positive flow rates... Thank you for your help..

Are you using a motor oil that conforms to VW specs (hint: all are synthetic)?
 
Other than that, if you popped the hood right after driving the car at high speeds, the turbo could get hot enough to glow. That's why its a good idea to let the engine run for a couple of minutes before shutting it down to allow for the temperature to stabilize.
 
Check the engine temperature gauge. The needle should be dead center (190 degrees) F.

#18 of 62 Help! Conflicting Turbo Info by katmando90

Oct 09, 2007 (4:59 pm)

I am contemplating buying a Passat or Passat Wagon, but I am getting conflicting information about using premium fuel vs. regular fuel. One dealer told me that it was acceptable to use regular fuel because there is a sensor in the engine that automatically adjusts the engine/fuel consumption. Another dealer told me that using regular fuel will lower fuel mileage (makes sense to me because that is what happened when I previously owned a car that used premium fuel) and that the turbo would be damaged by the regular fuel. Both cannot be correct...or maybe they are both wrong...or does the truth like somewhere in between?

1) It is acceptable to use Regular fuel but not recommended.
2) Regular fuel will have absolutely zero affect on the turbocharger. Period, full stop, the end.
3) Running low octane fuel in a 2.0T will cause the ignition timing to be retarded so much so that at wide open throttle, the maximum power output will significantly reduced.
4) Running low octane fuel in a 2.0T will cause the ignition timing to be retarded so much so that at any given cruising speed, the fuel economy will be reduced to the point where you'll end up paying more for fuel for any given distance traveled than if you use the recommended fuel.
 
Best Regards,
Shipo

Thanks. Appreciate the information. Sounds like neither dealer was quite right....

#21 of 62 oil in cooling system /overheating by rwheeler1

Nov 05, 2007 (12:22 pm)

2002 1.8t passat.my car overheated and dumped all the coolent.when i removed the filler cap the resovire was full of oil. called the vw dealer and questioned the service manager about a headgasket problem he says its most likely the turbo since the car is not smoking or running rough. i removed both the oil and coolant lines from the turbo and there is oil in the coolant port.since the dealer is 500kms away i have to do this job. so would this be a seal replacement or a complete turbo job? new turbo is 1250 bucks. or would you know where i could get mine rebuilt?tks roy

#22 of 62 2000 Passat 1.8T manual by ifco

Dec 09, 2007 (11:20 pm)

Where to begin. Turbo blew, oil in the coolant about 2 years ago. VW cleaned out coolant system with Simple Green. That is all they ca use because of Environmentalist. About 6 months ago no heat from heater. Brought car to VW and now they say new heater core, $1200.00 to repair. Is there another way to clean out the core. Also trunk leaks for no apparent reason. Any suggestions??
