Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Any 996 owners ? I got a 1999 996 convertible, recently purchased & when I turn on the climate control to blow out of the dashboard vents, there are small pieces of black sticky foam.... I'd think any insulating foam would be on the outside of the vent tubes not on the inside where 20 year old crusty degraded foam would break off & spit at the occupants.... Anyone have this ? do I need to take my dash apart & replace the vent tubes or something ? Many thanks.. NOOB 911 owner....

POST 2Original post

It�s very common and happens to 99.6 % of all 996�s. I just live with it.

POST 3Original post

Happened on my 2002 VW Golf TDI as well..Common on older cars like this.

POST 4Original post

Search the forum. lots of info on how-to repair.

POST 7Original post

Aren't the negative side affects once it all comes out?? Less insulation of the system? Heat not working as well? etc.

POST 8Original post

If you patiently read through the thread you will see the flap doors should be a solid, to block air when in the proper position. The flap doors are made of metal with large holes to reduce weight, and they are covered with foam to seal off the holes. When the foam comes off the doors air movement will travel where it should not travel. Read the thread and look at this LINK
