J2005

We bought a certified 2003 A4 back in March from a local dealer. After about 2 weeks it became obvious that there was a problem with a very musty smell coming from the A/C each time the car was started. It's been back to the dealer four times and they still have not been able to fix the problem.

On the third visit they even showed me a service bulletin from early 2005 detailing the issue and a proposed fix and acknowledged that it's a known problem. They performed the fix recommended in the bulletin, but it didn't seem to do any good. After the last visit their answer was along the lines of "We know it's a problem but we just can't fix it. I'm afraid you're stuck with it."

This is an unacceptable response. I know from dealing with other car companies that you can usually call a regional rep. to escalate the issue, but I'm not sure who that person is for Audi. Can anyone here point me in the right direction? We're in northern NJ if that helps.

Thanks, J.

nothing the dealer has done could fix that... i guess i got used to it... it does go away after a few seconds anyway

wow, it never bothered me that much...

There's spray it on the input ports (one by your right drivers foot) and one on dash (where the air isn't blowing). while a/c is running. not too much of this stuff.

then maybe take the outside air filter out, replace it, and spray some in b4 you replace it.

the ish annihilated cigarette smoke which is probably even harder than your mold.

ozium is basically a not bad smelling lysol.

This is the only thing I found to work. I'm amazed that car makers don't have an access port to the evaporator from the passenger footwell to spray in fungacide to eliminate the problem. I know of owners who have fished tygon tubing up the evaporator water drain and sprayed the evaporator in a more efficient manner. The smell goes away in the winter time in snow country.

Shouldn't this be the responsibility of the dealer to fix?

my moms BMW did.

leaving your air on recirculate... when you do a flap is closed so the air doesn't escape (ie it re-cools the cool air already) well when you leave it on recirculate and turn off the car if the flap does't open and water drips in, you can get mold.

frankly id assume the car would be designed to open this flap... im not sure if this is true or not, thats what i heard a while back and it made sense to me... but its already too late to do anything about it

Because I get the smell even after fresh filters for the initial turn on of the A/C, and it goes away in a few seconds

it goes away a few seconds later, nothing permanent
