SEPTEMBER 2007 -- VW is recalling 340,000 MY 2005-2008 Jetta and MY 2006-2008 Rabbit, GTI, and R32 vehicles for failing to comply with the requirements of Federal Motor Vehicle Safety Standard No. 108, "Lamps, Reflective Devices, and Associated Equipment." Some vehicles may not have had a required cap installed which disables the headlight horizontal aim and some vehicles may contain a cap that disables the vertical aiming screw. Noncompliance can inhibit proper headlamp aim adjustment for roadway illumination. Improperly aimed headlamps could cause reduced road visibility, increasing the risk of a crash. Dealers will inspect for the presence of a cap in the socket of the low beam horizontal aiming screw and install one if missing, and inspect for the presence of a cap in the socket of the vertical aiming screw and if present, the cap will be removed. The recall is expected to begin on or about October 31, 2007. This recall was the subject of an investigation, OA-108-070412I, conducted by the Office of Vehicle Safety Compliance. 07V442
