Here's a thought... is it possible that the radiator cap is not keeping appropriate pressure in the cooling system? Or the cooling system has a leak that is not apparent?
If the cooling system is not properly pressurized the antifreeze can expand and push out into the expansion tank. This condition will also reduce the cooling system's ability to keep the engine temp where it should be, possibly causing overheating, which in turn expands the antifreeze even more.
The radiator cap should hold around 15 psi pressure in the cooling system. It might be worthwhile to pressure test the cooling system and the cap. The former will reveal any leaks that may exist in the cooling system. The later will tell you if the cap can keep the pressure up.

The thought that crosses my mind when reading about this (fan noise) problem is... the fan will run even after the car is shut off to cool the engine. This is normal. It is possible for the fan switch to become locked in its on position. It is a temperature sensitive switch. It is a relatively inexpensive part and should be located in a relatively accessible position (not sure where). I would suggest that you replace this fan switch.

I have a 2000 VW Passat with the 1.8t ATW engine. I drove it for 190,000 virtually trouble free miles...then it ate the timing belt. I had the top end of the engine rebuilt because when the timing belt went, it took out a number of valves etc. Anyway, new top end, water pump etc was installed. It ran perfectly for about a day, then the idiot light circus began. Here are my questions:
1) The check engine light came on first, and after checking the code it says that my Air Intake Sensor is bad. This isn't the same as the MAF sensor, right? I think that I have read somewhere that it may be possible to take this sensor out, clean it and perhaps it will work again?
2) My engine temperature light was on. I could see that my engine temp would stay really low, then jet to the extreme, so I had the thermostat changed, and now the engine has no temperature problem. BUT, my heater has a mind of its own. It comes on, and then goes off (the fan works perfectly). Is there a valve, or some kind of sensor that controls the heater? This is not the electronic climate control system.
3) ABS fault. My brakes work fine until you get almost to a complete stop, then the ABS engages. Some days the ABS light will come on and the brakes work fine, but the ABS will not engage. Most days, no light, but the ABS engages just before full stop. Anyone venture a guess?
Thanks in advance for any help.

1) I'll take a shot at the Air Intake Sensor question. I'd like to see the actual code, but it sounds like you are referring to the Air Intake Temperature sensor.
I had a CEL and pulled the code at a local Autozone store. My sensor showed as intake temp sensor showed as bad. I pulled the sensor and cleaned it (I may have used brake cleaner spray, I don't actually recall) and reinstalled it and it never threw another code. On the AWM engine, that sensor is located on the intake manifold and has two hex bolts holding it in place. Very easy to find and clean yourself. Not sure where it is on the ATW.
Post your actual codes to make sure...
2) Heater issue: Is this with the Climatronic system, or the manual controls? Could be something as simple as air trapped in the coolant system.
3) ABS: Sorry, I've got nothing for you on this one.

Hi: Had the same problem with my 2000 GOLF at 75,000 miles. The cheap VW water pump froze, and stripped the teeth on the timing belt. It took out valves etc.
When they put it back together, they had to completely reboot the on board computer.
And now...VW says to replace the timing belt every 60,000 miles.
Oh, and the new water pump has aluminum innerds. jesss my 2cents.

Yes, you are right, it is the Air Intake Temperature Sensor. I will remove and clean it and see what happens. --thanks.
My heater is the manual control kind. Hmmm. I was wondering if there was an electronic control of some kind between the radiator and heater core...
Thanks for your suggestions!

i have the ABS problem. mechanic said my abs wires were stripped at the ends and they're shorting themselves out, so the ABS device is going to malfunction. Usually when the road is dry it should work fine as opposed to a wet road, but Ive noticed the problem regardless of weather conditions. So I havent actually gotten around to getting it fixed yet. So I have no input for you but its definitely a job for the dealer because they would have the right wire and stuff. I don't know if the problem actually will go back up to the actual ABS module but I am afraid to find out since its a VDUB.

If you decide you need to replace the ABS controller on your Passat or any other car for that matter. Consider having it rebuilt, instead of putting a new one in. In a car that is more than 3 or 4 years old I think this makes more sense than installing a new part.
2.5 years ago I had this company rebuild my 2001 Passat ABS controller
At that time it cost me $250, and it is still working great! They provide a 3 year warrantee.
I also had them do my Volvo S80 ABS controller more recently at the same price.
I don't work for these people, nor do I get any compensation for recommending them, I am just a happy customer.
#2543 of 3341 2006 Passat B6 Maintenance?
Feb 09, 2008 (1:48 pm)
I would like to know if it is possible for an owner to replace the air filter on this engine?
The dealer will not talk to me about any maintenance unless they are going to do the work. They go dumb when you ask a question, and lawyer up on you!!!
I have mastered the oil changes, with the oil draining kit but the cover on the engine is not a simple screw off. Can I get some direction out there on replacing the air filter??

oh man its a piece of cake. Well it was for a 1999 Passat GLX. I got my filter from K&N and they have instructions specific to each vehicle with pictures and it was not bad at all. In general, Just follow the intake hose from the front of the car to where it turns into a rectangular box or something. Then unhook the clips, there should be like 4, 2 on each side. Well make sure everything else is out of the way and just pop the top off. There is your old filter.. take it out and put the new one in. thats it and then obviously put everything back the way it came.
You should double check for your vehicle, visit K&N website here: http://www.knfilters.com/search/product.aspx?Prod=33-2878
I dont see where I can access the instructions there, but they sent me instructions with the air filter I bought from them. Call them or something! Good Luck
