AC drain pipe clogged (so stinky)

**Fireside** · 07-06-2013, 07:45 PM

Hey all,
Just wondering if anyone has had to deal with a clogged AC drain pipe, and if so, where is it?

Over the past week I've noticed a foul smell every time I got in the car, it seemed to get worst every day.

To the point it was almost unbearable, it is an all consuming stink, just like the one out of Seinfeld!

I steam cleaned the cabin top to bottom, coated it in bicarb, air fresheners and even bought a new cabin filter and the stench lives on!

After some web research, I've deduced that it must be bacteria, fungi and spores growing in the vents... and probably a blocked AC drain pipe.

Has anyone had this problem before?

I'm attempting to sort it tomorrow but dont really know where to start, any help would be much appreciated!

it wont be a blocked drain. if it was blocked you would have wet carpets by now and as the weather is not humid any more (Brizzy anyway) you dont see the a/c dripping under the car onto your drive... a lot of cars are smelling like this at the moment usually when the a/c is turned off and just blowing air.... you can buy a proper bacteria spray for this issue... its like a insect bomb you let off in the cabin with the windows closed and recirc turned on for a while..sure places like autobarn would sell it....VDUB....

Thanks VDUB!
No carpets are dry, so mustn't be the blocked drain.
I'll check to see if there's water leaking. Yeah the smell is discussing, and I've got a really strong stomach but after an hour, it makes you wanna hurl!
I'll swing down to repco tomorrow and see what I can find.
Thanks for the tips!

usually the smell goes when the a/c is on.. the smell is usually with just the blower on and A/c turned off..... you might not see the a/c dripping as its not humid and its not having to take moisture out of the cabin air... good luck...VDUB...

Rotting leaves in the air intake under the wipers on the back edge of the bonnet?

Is it an old sock smell?

I had this smell problem with air con or just the fan. I removed the pollen filter, which is not due to be replaced according to VW, and no more smell.
