Hi folks! Just wanted to preface with saying that I'm very excited to be a part of this community. I have grown to love my Audi over the last couple of years and I greatly appreciate the effort put forth to sustain a community like this which offers help for other (sometimes slightly less car-savvy) individuals, as well as a place for enthusiasts to meet and share ideas. Hats off to you guys!
On to the issue. I'll try not to make this explanation too long, however, I do think it's best to start from the beginning and be thorough so that users can have that information available when they help out instead of having to ask more questions about the problem. To preface, the vehicle is a 2001 Audi A6 4.2 (c5).
Several months ago I noticed that there were water spots in the headliner on the C pillar, passenger side. With some research (on audizine!) I was able to diagnose the problem. I decided that the most likely culprit was the sunroof drains being clogged or otherwise not functioning properly. I knew that I needed to pull back the headliner and check, but I was unsure how to tackle the issue. I decided to take it in to a local car interiors shop here in Chicago, and they were very knowledgable about headliners, sunroof drains, the whole shebang. They pulled down the headliner for me, found the issue (the hose was disconnected near the C pillar, passenger side!), fixed the issue, and replaced the entire headliner. I thought all was well until they started telling me about the extent of the water leakage. They said that they found the footwells to be damp, especially the front driver's footwell and attributed this to the leakage of the sunroof drains. I do believe this is possible, however I have read information (here on audizine!) about faulty battery tray (?) drainage causing wetness in the driver's footwell. So this brings me to my first question, what likely caused the leakage? Have I likely fixed the problem, or is the water drainage from the battery more likely the culprit? I figure either way, I should check to make sure. However, I figured this would be a good place to ask for comments/suggestions about that situation.
The reason why I explained the above issue first is because I believe it to be directly related to the larger issue at hand. I believe these to be related to the dampness of the footwells only because I did not notice this issue before this happened. The issue I am having is related to the doors, interior lights, and the "open door warning" indicator on the cluster's display. I will break down what is happening in bullet points because I feel it's easier to understand the separate issues and how they are related.
-- The driver side FRONT door -- does not trigger the dome light, does not trigger footwell light, and there is no "open door warning" on the cluster's display.
-- The driver side REAR door -- DOES trigger the dome light, does not trigger footwell light, does not trigger the "open door warning" on the cluster's display.
-- The passenger side FRONT door -- DOES trigger the dome light, does not trigger footwell light, DOES trigger the "open door warning" on the cluster's display.
-- The passenger side REAR door -- DOES trigger the dome light, DOES trigger footwell light, and DOES trigger the "open door warning" on the cluster's display. (only one working completely [>_<])
-- The TRUNK -- DOES trigger the "open door warning" on the cluster's display.
The research I have done here on audizine has led me to three possible problems (probably a combination of the three, actually): either the CCM is malfunctioning from the dampness in the driver footwell (no sign of damage to the CCM, though it was damp), OR the door latches are malfunctioning (I've read about door pin switches, microswitches, and sensors within these latches that can malfunction), OR the wiring/lighting units themselves are damaged (or bulbs need to be replaced!).
I could go ahead and replace 3/4 door latches and the CCM, and I feel this would most likely fix the problem. However, I'd first like to check to see if anyone else has had this problem and/or knows exactly what I'm talking about and knows the culprit from the breakdown I just gave. So, I come to you great members of audizine for assistance with this matter. Any direction/comments/suggestions that any members can give me about this issue would be greatly appreciated! I will be following this thread closely as I settle into my nice little audizine nest :)
Thanks so much for reading my wall of text and for any help in advance, it is much appreciated!
