THX so much! I went to the dealer and it was indeed the sensor. Got it replaced... $325 THX very much for your help!!!! Jen

This exact thing happened to my Passat. It's very annoying in addition to being embarrassing, people probably think I'm trying to steal my own car! Anyway, I brought it to a mechanic who specializes in VW/ AUdi. I had to replace the alarm system which cost about $300. I hope it's no more than that for you!

hello i will buy a 1999 beetle with 150,000 the owner says it neads motor mounts,,i will buy it cheap 1500dlls ,,what parts must be replaced besides the motor mounts it has 150,000 miles,i thinking on a mjor tune up

i have a 2000 Beetle that ive had for over a year now. It suddenly has a water(or something) leak on the rear floor on the driver side. its been raining a lot but this problem has never come up before. Its SOAKED. i dont know what to do or what the problem is. any ideas?

Can air bubbles in the upper line of the radiator reservoir be coming from a leak in the intake or exhaust manifold gasket?
I get no water flow in the upper water line, just a little smoke fumes and water spurts. Even with the thermostat out and engine at 4000 rpm!!! The cooling system slowly builds up pressure with the reservoir cap on tight and then overheats. Boiling occurs from the bottom of the reservoir. When I clamp off this lower line, the boiling stops. Might be alot of air pressure going through this line.
I checked the water pump. The impeller is tight on the shaft. It looks OK but I believe air in the system will make the pump lose prime and become ineffective. It seems there is no water pressure at all.
At 4000 rpm's, a slight increase in water flow is seen in the upper radiator hose with air bubbles but still no flow at the upper reservoir line. Just little spurts of water! I put in a clear hose to observe the flow for the upper radiator hose.
Fans do not ever come on but my first concern is the lack of water flow in that upper reservoir line and the air bubbles. I'm sure the pressure check will show an air leak. The question is where. If I hot wire the fans, they run just fine.
I'm going to pressure check the cooling system today and hope it's just an intake or exhaust gasket. Engine runs fine with good power and smooth idle. No water in the oil or oil in the water. I believe compression is OK but have not checked it yet.
There is an obvious milky white buildup on the valve cover cap. Was told that could be just from condensation but it's pretty thick and should not be there.
Any suggestions would be appreciated.

First things first... DO NOT LEAVE THE THERMOSTAT OUT OF A VW ENGINE!!
VW uses a "bypass" cooling system in which the thermostat is used as a bypass-valve to control the flow of coolant thru the engine. As the thermostat opens, measured amounts of coolant from the radiator is allowed to mix in with the master-flow.
Leaving the thermostat out of the engine totally messes up the cooling system. The coolant does not have anything telling it where to flow. Without a thermostat, all the coolant may 'bypass' the radiator and the engine may overheat (or worse!)
NEXT: Once you have thermostat in the sytem, if there is no coolant "peeing" from the small hose in the top of the pressure-canister...then your waterpump is the problem.
The waterpump MUST be replaced when the timing belt is replaced. Your 1999 should have had the TB replaced at least once by now. Are you *certain* that the waterpump was replaced at the same time?
Additionally, there are 2 types of waterpump available for VW engines.
I always insist that they install the Brass-impeller type when my timing-belt is replaced. This is because the Plastic-impeller type have a tendancy for the impeller to dislodge from the shaft and stop pumping.
Here are some details about the plastic-vs-Brass waterpump.

i am converting a 77 fuel injection beetle to a carburetor. i have solex 34p1ct3 carb. and i am wondering since i have to buy a new duel port intake manifold but do i have to make a difference of what type i get for it. like if theres a difference between if it says 66-70 or 71-74 manifold. or does it not it not matter. and if it does make a difference what is it? and does ayone have any recomendations of what to buy?

I have a 2001 beetle I just purchased put new compressor, condessor,dryer the works Charged a/c an Heres the thing It doesn't kick on till you Rev it up till about 1500 or more When it engauges the first time compressor stays on for about 4 secounds then cuts off for a sec then right back on an gets shorter an shorter Then after fourth Kick on it goes to just one for a sec then back of an so forth But only kicks on when the car is rev up. I have checked to make sure it has proper freon in it. I posted this on other websites an no luck yet either????

My logic tells me the thermostat is closed while the engine is cold so that the water is circulating thoughout the engine but none going through the radiator. As the water heats up past 190 degrees, the thermostat opens up to allow water to flow through the radiator to cool the water.
No thermostat means constant radiator flow even with cold water. My problem is no water is flowing through the upper radiator reservoir tube even when the engine goes to 4k rpm. There is no constant flow, just a little fumes and a little water spurting out but no change between idle speed and 4k. The water pump checked good and is tight on the shaft! Go figure!!!
Also, there is really no water pressure in the upper radiator hose. At idle or 4k rpm's. That doesn't seem right to me.
Do you see a water stream on the upper reservoir line at idle and then an increase at 4k? Also, squeeze that upper radiator hose and tell me if you feel a pressure increase from idle and then 4k rpm's. You can actually do this yourself by reaching for the throttle connection and reving the engine with your free hand. It's behind the air filter box near the firewall.
