E91 interior condensation

LEDZEP · 11-26-2006, 06:10 PM

So, the last week or so, with the changing temperatures in the early evening and the moisture in the air - our E91 has been getting condensation on the INSIDE of the glass. The worst one is the rear window, and sometimes the inside of the windshield.

Has anyone else had this problem with any E9x? I had a previous thread discussing the ill-fitting panorama moonroof and how noisy it is because it doesn't seem to seal completely. I'm wondering if the moisture is coming in there.

I plan to call my dealer and tell them to give me a loaner and I'll take my car back when it is impossible to get a molecule of moisture into the car. I've had a lot less expensive cars that DID NOT have this problem!

While at my BMW Center last Friday (test drove the new X5) I noticed that every new 3-Series parked on the lot had moisture on the inside of the back glass. I thought it was unusual.

I have noticed some condensation on the inside rear glass of my E90 over the past week or so. However, I hadn't cleaned the inside rear glass in a while (real PITA to get the glass back there). The dirtier the glass, the more water will condense since the water actually needs something to start the condensation process and really won't easily on clean glass.

It certainly should be unusual. My sedan has never had this problem, nor did the wagon until this fall. I don't intent to tolerate it though.

I'm not sure about the weather in DE over the past week, but it's been rather warm here during the days (55+) and then cold at night (30s). So any air that would be in the car from the day would have a dew point above the outside temperature and therefore would try to condense on the coldest part of the car (the windows)... So it really didn't surprise me to see some.
