7L is the 2002-2010 Touareg model. 7LA is the 2003-2007 model. 7L6 is the 2007-2010 model. Most Touareg parts for both models start with 7L. Lots of other parts are shared across the vag group cars and will have a different part number.
When looking for parts you should take into consideration your engine and your year model.
So 7L means a Touareg 1/2 (T1/T2) part but not necessarily the right one for your model.
