Dipstick for the Q7 TDI with Engine code CATA as well as the 2009-2010 Touareg with the CATA engien code.
2011-2012 Touaregs were not equipped with a dipstic only a cap. This dipstick can be used in place of the cap. Engine oil levels may be 1/4 of a liter off. Many people like the ability to manually check thier oil instead of relying on a sensor
