Hello did you install the exhaust system? if so i have some questions, could you give some info?
1. -what are the main difference between the single and the dual tips?
2. -Is the fuel consumption reduces with a system like this?
3. -Is a chip required for the car to run smoothly with these exhaust? (if so what kind of chip, where to find, how much, how difficult is a chip to install)
4. -Are you aware of any engine problems with this type of exhaust? (engine check light etc...)
5. -In Colorado we need to get an emission/inspection done on the car every 2 years, would an exhaust like this on the car comprise the test?
6. -How difficult is the system to install? Do they send you an installation manual?
mj99 I've been trying to get rid of a colling system CEL on my 2002 Eurovan (VR6 24V) for months. Can you give me more information on this possible wiring fix. I have installed 3 new green sensors and a new thermostat (big PIA) and the temperature needle lives way down on the left side still and is illuminated by the CEL.
Re: Coolant Temperature Sensor Install 24v VR6 (orange1218)
thanks for the great post orange.
I have a p0118/p1381 code and a black top sensor on my 03 jetta gli so it looks like I'll have to replace it too. I called the local vw dealer just to see what they'd charge and was quoted $280, but they also mentioned that aside from the replacement of the sensor there is a wiring fix that's necessary. anybody know what they're talking about? Also, I noticed many people stating that their temp gauge isn't working right, but my gauge seems normal. is a sensor failure always associated with a faulty gauge reading or is it possible to have a bad sensor with normal readings?
I had the check engine light on my 2002 Jetta GLI come on and had the P0116 error code. After digging around on the web I found this great DIY article (and the thread devoted to the 24V VR6 which has a link to this).
I did have the black top part and I have noticed my MPG went down lately, so I figured this must be it.
I put the new sensor in...
However I now have a bigger problem...I can't find the wire harness anywhere! Then I got to thinking, and I'm not even sure if it was there when I took out the old one. I'm afraid I'll have to take it to the dealer to replace the wire (or find it if I'm blind).
I'm just not sure how it could disappear, I know its cramped in there but really just to fall off and be gone? Anyone else ever have this issue?

First I'd like to say thanks for this forum. You've helped me fix a ton of stuff on my Jetta over these last few years, door light switch, coil pack seal, etc.
I'm having trouble replacing the retainer clip onto the new sensor. It just doesn't want to go that last 1/2". I've already broken one by trying to push it down with a needlenose pliers (which is how I initially removed it) and am now down to my last clip. Any ideas or tricks to getting it on there smoothly?
-The sensor is pushed all the way in, all I see is green through the clip slots.
-I did remove the old O-ring and replaced with a new one.
Just did this on my '01 12V, 1.5 hour job, saved me $200. Thanks for this DIY!
Two tips, if anyone can use them:
1. I bought two extra clips, but ended up re-using the old one-- I didn't break it taking it out, and it had bent over the years to conform to the bracket that's in the way, so I thought it was less likely to break as put it back in (except that that plastic is old, of course). Worked great.
2. I found that I couldn't get a hex wrench into place to loosen that bracket, but I could use a big screwdriver prying NOT TOO HARD against the head (make sure you're not prying against anything plastic!) and move the backet about 3/4 inch, making it easier to get the clip back in.
Great write up it was very simple to follow, unfortunately I found it after I bought just the sensor from Advanced Auto Parts. Ended up just going to the dealership for extra coolant, an extra clip, and a new O-ring.
Had a bit of a difficult time getting the clip back on but patience is key here so you don't drop it like I did.
Thanks for the help!
replaced black sensor with greentop from factory this weekend while i had some time, mainly because my temp gauge was not giving a reading or was very intermittent. (aka - always reading 0, or would randomly give a normal reading at 190 or in the middle, then go back to 0) have not reset the thing yet, just was hoping anyone would have some thoughts or suggestions... is there a temp sending unit elsewhere other than this green top on?
Also, instead of removing long allen head bolts holding in therm housing, I removed 2 screws holding the vacuum mechanism attached to the intake manifold and rotated it down in order to get my oversized hands down there. (sorry for not knowing the technical term for it, anyone please correct me if understand what im trying to say)
Lastyly, if you plan on doing this, it is possible to spin/rotate sensor around while C clip is holding it in. Since clip for the plug was on bottom of the sensor and couldnt see what i was doing.
Thank you in advance for replys
