1999 VW New Beetle Coolant Temp Sensor

Is this for a ignition coil output stage open circuit? If so you need to rerun the ground wire. Just but the wire close enough to the coil that you can still get to the wire and splice another wire to it. Just splice a wire to the brown wire and run the rest of the wire to a ground lug under the battery. You will need to remove the battery and the tray. Also when you hook the battery back up make sure the key is on. This will reset alarm and radio. Remember, you are grounding the coil so the wire should go from the coil to ground. Hope this helps

There is a recall on the brake light switch. VW should replace it for free.

-----------------------------------------------------------------
Defective brake lights on Golf, GTI, Jetta, New Beetle and R32 are a potential safety hazard and should be replaced. February 26, 2007 - NEW YORK (CNNMoney.com) -- Around 800,000 Volkswagen vehicles have been recalled Monday because of faulty brake lights, the National Highway Traffic Safety Administration said.
The 790,000 vehicles include Jettas, New Beetles, Golfs, GTIs and R32s...all in the United States.
The specific years and models affected are:

• 1999-2005 Jetta sedans
• 2001-2005 Jetta wagons
• 1998-2007 New Beetle
• 2003-2007 New Beetle Convertibles
• 1999-2006 Golfs and GTIs
• 2004 R32

The malfunctioning brake lights and brake light switches could fail to come on or remain stuck on.
This recall expands on one announced by Europe's No. 1 carmaker last year, when 362,000 Jettas and New Beetles were recalled due to the same defective part.
Volkswagen said that dealers will immediately be prepared to accept service appointments to perform the repair at no charge, but the notification process isn't scheduled to begin until April.
NHTSA did not say if any injuries had been reported linked to the defective brake lights.

Could be dirty abs sensors attached to your brakes. I would clean them with brake parts or elecronical cleaner.
Other possibility is a faulty ABS system.

See if the battery can be changed

You need that sensor or you will overheat the heaters and may start a fire. I imagine that the sensor shuts them down when they reach a certain temperature.

Try going to the dealership and asking the guys in the shop there. They would be the ones who could really tell you whats going on.

I hope this keeps you out of the hot seat!

Go to the VW Vortex site, or VWFixx, or RussTech and stroll around the forums. Find someone near you with a Vag-Com and get the codes. Or go to AutoZone and get the codes.

I've got a 2001 1.8T New Beetle and I am alwasy getting codes. Have repaired and replaced, repaired and replaced, a number of things. O2 sensors, hoses, valves, sensors, etc, etc., and couldn't do any of it without the VagCom.

Bottom line to help is codes, we need codes.

Yes it is that easy. It should be a 4 pin connector located on the transmission side of the engine head in a plastic flange. Best is to wait for the engine to be cold. Unscew the radiator cap to relieve pressure but screw it right back on. On the 2.0L engines when you unclip the coolant sensor little or not coolant loss will happen if you do this. Just unplug it, pull out the clip, pull out the sensor, and the seal which sometimes stays stuck. Install the new sensor with a new seal lubricated with some coolant, make sure it's well seated and reinstall the clip. The sensor is well seated if the clip fits right over the top, just make sure both sides clipped into position. Replug it fill the coolant with VW original coolant mixed 50-50 with water if needed and done. If you have a fault you might need a scanner to erase the check engine or fault in the cluster.

What's the reason for changing it? Eratic temperature readings?
