Hello, if it were me, I would take it back and have them do it. That should be part of the repair. The last step in the installation procedure is: "Check and adjust headlight if necessary." As you see by the Headlights Adjusting procedure you require a VAS 5107 Optical headlight aimer. Regardless, I would think that is still part of the repair. Also, you might check with the dealer on any recalls. I show Recall 07V4420000: Headlamp Adjustment Non-Compliance for some models. Last there is about 5 different types of 4 cyl Jetta's. I gave you the info for L4-1.8L Turbo (AWP).
MAKE/MODELS: MODEL/BUILD YEARS:
MANUFACTURER: Volkswagen of America, Inc.
NHTSA CAMPAIGN ID NUMBER: 07V442000 MFR'S REPORT DATE: September 17, 2007
COMPONENT: Exterior Lighting: Headlights
POTENTIAL NUMBER OF UNITS AFFECTED: 340000
Certain vehicles fail 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. Owners may contact VW at 1-800-822-8987.
