Replying to: oreilly79 (Jun 30, 2009 12:43 pm) 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.

| 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!!! | |

Heated mirrors aren't working and the owners manual doesn't identify the fuse. Where is it? Thanks.

Bluetooth wouldn't work under 60 degrees ambient. Dealer replaced last week. Now, Autohold unit is dead. Could it be related to the dealer's work? |

Yes, but I had to take it to the dealer and they went through the schematic to replace all the fuses. But even then, my car wasn't working correctly, and that's when we realized there was a the second "supplemental" booklet that came out later, which had the correct placement! When all was said and done, & $114 later, the tech gave me a nice ziploc bag with 17 extra fuses!!!!  They were put in all the extra spaces when my husband couldn't figure out where else to put them! But strangely I have other car issues, that I'll post separately, with my roof opens unexpectedly when I'm driving on the freeway, in our 100 degree plus heat... Not sure what's the cause yet. |

Ok, my fuses are back to normal,  but over the last two months, since I got my car back, I have been experiencing my sun roof popping halfway up unexpectedly, while the knob is in the closed position, and I'm curious if anybody else has this problem? I've tried to keep a record of when it happens (date/milege/time of day, where I'm driving, road type -smooth/bumpy, etc, if my A/C is on, and outside temp displayed) to see if I can see a pattern. I'm seeing it's usually on the freeway, no bumpy roads, though. And I seem to always have my A/C on in this hot Texas weather, and almost always, the temp is over 100 degrees.  It's happened about 6-7 times now. But you know, if I take it in, the dealer has to be able to duplicate the problem, in order for them to fix it and have it covered under warranty. It's got only 48k miles, so it's still under warranty. But, I need to see it happening more frequently, or get some ideas from somebody who had this problem, and resolved it, so I know where to look for the problem. Thanks for any suggestions! Even for the quirky problems, I still love my elegant, black Passat, with the Turbo and all the accessories! |

Replying to: hedgesville (Aug 16, 2009 2:42 am) But, if your car is still pretty new to you, you may not have noticed on the button, you have a little dot towards the top and you have to turn the knob towards the dot for it to turn the heat on. I didn't know that until after I had the car for about a month! Just be sure to turn it off afterwards, because it does use your fuel if it's left on. Happy hunting! |

I've read many post regarding this issue with the homelink & fuse 5. My fuse tests good. I also replaced the fuse just in case & the same thing. All the functions on the steering wheel (horn, cruise & radio controls) work intermittently (mostly not). Only 40K on car. I'd like to try disconnecting the homelink, but was unsure how to go about it. Message #198 sounded like my answer as we both have 03 models, but my visor must be different? I can't find a small disc to remove. It would have to be on the left side. Any suggestions would be appreciated.
