I need some help reconnecting the vacuum hoses on my '03. Had to remove tiptronic to repair it, and either have a broken vacuum hose, and/or am as lost as I can be. I can't figure it out. Here is the vacuum diagram from the trunk. Part of the problem is, that I can't identify all the parts. The "white" connector goes into the intake. Off of that is a "Y". The "Yellow" line (vacuum hose) goes nowhere that I can tell. I am sure it connects somewhere, I just can't tell where. It is long. The "Pink" end of the "Y" is open. I am sure something sticks in there, just not too sure what. The "Green" line (vacuum hose) connects to what I believe is the Resonance Flap Valve. However, it is either broken (and connects with the "Blue" line (vacuum hose)), or inserts into the "Pink" end of the "Y". Not too sure which. The other end of the "Blue" line (vacuum hose) connects to a 4 way "Cross fitting", that connects to the vacuum reservoir. Shown as connection #1 below. I guess the upper end of the "Blue line" (vacuum hose) could connect to the "Pink" arm of the "Y". Again, not too sure. It is entirely possible, that the "Blue" and "Green" line is a broken line. If this is the case, not too sure what would plug into the "Pink" on the "Y". #2 "White" line (vacuum line) attaches to a switch, that I believe is associated with the tiptronic transmission. The lower end of the hose connects to the "Cross" fitting that is by the vacuum reservoir. The "Purple" line (vacuum line) is attached to a valve that controls coolant that goes to the tiptronic. #3 Line disappears somewhere deep into the engine somewhere. Can anyone help? Thanks!

Hi, I am relatively new to the Porsche world. I bought a '99 996 about 2 years ago, and it has been running like a charm until recently. Earlier this year I moved from FL to NC, where winter exists. Around the time the temperature started getting near 40 degrees (which rarely happened in Florida), the engine starting exhibiting a very rough idle when starting cold. I got a code for a bad o2 sensor, but fixing that didn't seem to resolve the problem. No other codes, so I started going through a checklist of things to replace: MAF, coil packs, spark plugs. I cleaned out the throttle body. Nothing seemed to help the situation. Right before Christmas, my alternator died. I got a new one on Friday, and put it in today. In doing so, I noticed that there was a small crack in this hose: What is this hose and could it be responsible for rough cold idles? Also, what does it connect to and how hard is it to replace it?
