#269 of 291 Re: Having window trouble, 98 Passat [lucky_charms] by veedub4 Jun 01, 2009 (9:28 am)
Replying to: lucky_charms (Feb 11, 2009 11:50 am) I know how you can take power away from your windows, but then your doors will not lock with the key you will have to do it manually and your alarm system will not activate. If you open the doors, on the back ones there is a little rubber casing you can take it off and there will be two wire connectors. The big one which is usually black is the one you want to take off. This will take away the power fromthe door locks and the windows. The smaller one under it is for your speakers. You can leave that one in. I have a problem similar to this. When I lock my rear passenger door, the car will not recognize that it is locked. It makes the beep in the trunk, but eventually the alarm will go off. Also, when it is locked all of the dome lights blink, so I ended up just disconnecting the power for that door besides the speaker.
#270 of 291 Door Wirign and Alarm Problems by veedub4 Jun 01, 2009 (9:40 am)
I have a 1998 Volkswagen Passat Vr6. When I lock my doors using the key from the outside, it locks and makes the little beep. I noticed though that once I lock it, the dome lights start blinking and eventually the alarm will go off. I checked all of the wires that are in that litlte rubber boot thing you can see when you open the door, and they appear to be fine. I cant figure out what it is, so i currently have everything but the speaker in that door disconnected. I have heard that if you have an aftermarket stereo (which i do) that it may cause problems with your alarm system. I dont think this is the problem because I have always had it, and it never used to do this. Any help or suggestions? Thanks. -matt

Replying to: mole2 (Feb 25, 2007 1:43 pm) the gas lines on volkswagens tend to freeze easily. go to your local gas station and buy a bottle of i thinkits called heat. or heet. something like that. you pour it in your gas tank, adn it will unfreeze it and if thats the problem it should start right up.

#273 of 291 1999 Passat Wagon 1.8T lack of power & very poor gas mileage by oreilly79 Jun 29, 2009 (9:26 pm)
Replying to: veedub4 (Jun 02, 2009 8:58 pm) New!!!! Yippy! Need some help with my issues before I burn the beautiful Passat.I bought the car about 3 months ago and ever since I got it my gas mileage is horrible. At times in the city when I'm leaving a light, 6mpg and a the most I've gotten from a full tank has been 250 miles.Then it blew fuse # 14 that thanks to this forum was able to fix and find out what the hell it was. (Thank you all) Now from time to time the alarm goes off while I'm still sitting in it. None of that is a problem I think if I fix my gas mileage and try to get some better performance from it since it is also very slow and has no power. Is there anything that can be done or can anyone tell me some to do?

Replying to: oreilly79 (Jun 29, 2009 9:26 pm) You're not really telling us enough information to help you out. What is your MPG when you calculate by hand (Total Miles driven divided Total Gallons Used)?   Miles on a full tank is kind of meaningless....what constitutes a "full tank" for you? When the fuel light/chime comes on? WHen the MFA reads zero miles left? When the tank has been run dry? For example, in my '03, gallons used in these three conditions would be 12.25, 14 and 16.4. That would equate to 20.41, 17.85, or 15.24 mpg.   Gotta say, though, that stop and go city driving is hard on mileage in a 1.8T Passat, especially if you hit the gas hard.   Regarding power - heat soak might be part of your problem. Could also be a leak in the vacuum lines, your diverter valve could be bad - the list goes on.   The alarm going off - well, could be your comfort control module is bad. I've never had this issue so I can't really help you on that.   Have you pulled the codes on the cars from the OBDII at your local auto parts store? You can usually find some place that will let you do this for free - like Advance Auto Parts. Post up what you find and that may give more clues to get you help.

Replying to: altair4 (Jun 30, 2009 5:42 am) Well sorry, but i'm new to this forum and son't know what to write or ask. My tank is about 16.5 gallons and all it would last is max 250 miles. I do drive alot in the city and I get crappy MPG. I recently had it scanned and it came back the temp sensor (P0116) and the boost sensor (P1557). City MPG is around 12-15MPG and highway 21-25 MPG driving it easy due to the gas comsupmtion. When the fuel light comes on, I usually have traveled around 200-210 miles and have about an extra 20-30 more to go before it runs out. Never driven it dry so I wouldn't know what would be the total on the full tank. Don't know how to get those numbers you're asking me for or you are relating them to sorry. About the alarm, I've read it could be the CCU located under the passanger side seat witch i'll check in these days. If there is anything else you would like to know that can be of help, let me know. Thank you anyways for your answer.     Replies to this message: altair4 (Jul 01, 2009 3:01 am) oreilly79 (Jul 01, 2009 9:10 am)

Replying to: oreilly79 (Jun 30, 2009 12:43 pm) To calculate your mileage, simply write down the mileage when you fill up with fuel. Then write down the mileage again when you next fill up. Get the difference and then divide by the number of gallons you used during that period.   P0116 is likely from the coolant temperature sensor having failed. Not an uncommon problem on the 1.8T engine. Don't know if you are a DIY kind of person, but the coolant sensor is located, IIRC, on the back side of the engine, between the engine and the firewall. Very likely cause of your poor mileage as the engine management system is getting a signal that the eninge is not warming up. The engine is running rich and will definitely impact your mileage. .   I don't have the time right now to research your second code, but I've seen enough around the web to highly suspect that it's related to your lack of power. You are probably running with no boost from the turbo. Could be a leak in the system, could be the N75, or the divert valve. Replies to this message: oreilly79 (Jul 01, 2009 9:10 am)

#278 of 291 Ignition Module by jett4 Jul 02, 2009 (2:21 pm)
I am in the process of replacing my ignition module on my 99 Passat. When I removed the old module, I noticed a gooey film like paste on the bottom of it. Does the paste serve as a seal? And do I need to seal the new module before I tighten it down. And if so, what kind of sealer can I use? Please help....I'd love to drive my car this weekend!!!
