Water and debris was ingested in to air filter box resulting in water-soaked air filter and the potential for catastrophic engine failure. It is unknown how long the problem has been occurring because I had never checked my air filter before. The vehicle has periodically been driven in rain over the last few years but never driven in deep or standing water. It appears that drains are not able to drain properly and water is entering the box somehow when it shouldn't be be able to.
Water ingestion into air intake from design flaw. Changed air filter based on warning thread located at club Touareg online. If you drive a 2011-2017 Touareg please check your air filter. Many owners have reported complete engine failures and vw refused to take responsibility. Vw issued recall in china but are denying problems here in na. My air intake tube leading up to the airbox was full of water and the bottom 2-3 inches of the air filter itself was falling apart, soaking wet and moldy. It was basically sitting in water. Our vehicle in only used on road for commuting - never off road or on deep water situations. I'm attaching photos of my airbox full of water and the air filter I changed.
