7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Angry Smelling A/C when turning on

I got a problem, and it's not about me this time

When I turn on the A/C the first time i jump inside my car after work, it smells bad. Initially, I thought it was the upholstery, but it's not. The smell sticks around for about 30 sec, then it goes away.

Anyone experience this at all? Please help!

Every one of the 4 750's I've owned did the same thing, I think it's the foam insulation or plastic they use in the a/c system breaking down. No matter what I've tried I can't completely eliminate the odor on start up. Tried every flush, cleaner, and deodorizer I could think of and nothing worked more than a few days. Originally thought the drains were clogged but that wasn't the problem.

If you can figure it out, let us know.

Both you members are in very wet humid areas. I'm wondering if we have some type of mold growing in your AC system. This has been a problem in other vehicles. There is some products out there to cure this. I would talk with one of your local shops. To see what they're using on vehicles in general.

As we only get 3 inches of rain a year. I don't know what the product name is....no great need for it here.

Seattle has been bone dry all year, Rick.

My ac smells, but it goes away in about a minute. What about using non-chlorine bleach in a vaporiser.

I think this problem is specific to humid areas like where I live. If you run the A/C all the way home and abruptly turn the car off, it seems that it leaves good conditions for mold to grow in the ductwork overnight and you get that awful smell the next time you start the car and run the ventilation.

There are a couple of things you can do: 1. run the heater at full power as you get home and shut off the ventilation system and leave the hot air in the ducts. The heat kills the mold for a little while and you have to repeat often. 2. As you get close to your destination, turn the A/C off and let regular air circulate in your ducts for 5 minutes and this will prevent mold from growing in your ducts.

I used a long plastic tube I bought at Home
Depot to get the AC cleaning spray
deodorizer as far inside as I could . It was
the plastic tube you use when hooking up
The water & ice maker on your refrigerator
. I used almost 2 cans & it's been all good
since about June

No such thing as dry in Seattle.. Your humility was at 44 to 66% today.. I don't think I would put anything except approved air-conditioning solution in the system. God knows what chemical reactions might occur with something else.

I did a temporary assignment up in Portland, OR for about a year and brought up one of my cars from AZ. Within a few months it started to smell like mold. After bringing the car back to AZ it mostly cleared up but was never quite the same. It's definitely the higher humidity there. Make sure your A/C drains are clear first and try some of the treatments other have suggested.

You need to run an ozone generator in the car.
Youve got mold .mildew in the ducting ( bacteria ) causing the smell.

You run the ozone machine for 30 min inside the car . On recycle. Replace the cabin filter with a carbon type. Make sure ac drains are not blocked. Do this every 6 months. Its the only remidy with out chemicals.

Ozone kills bacteria, ozone is used to senitize hospitals to hotel rooms and even drinking water in third world countries.
Its also harmhul to humans though so make sure its aired out properly befor driving.

Good luck.

I've looked at some Of the Ozone Generator online, there are some for the car too, but I'm a little skeptical about those ones, they're kinda tiny, not sure if it will do the job. However, the big one is kinda expensive, is there one that u recommend AActive?

I bet the use of an ozone generator will turn all the parts in your interior into dust.

This is MWS's video on his ozone treatment of his M6. It didn't do any damage to his car. The prior owner was a smoker,and used cologne to mask the smell. Seems to have worked for him.

We use a Cliplight The Purifier, its specifically for Automotive, it is expensive though.

It does come with a wall charger and I have used it in small rooms as well.
