Dear Volkswagen Owner:
We are writing to inform you of an emissions service action on some 1999-2002 Jetta, Golf and GTI VR6 engine vehicles. Our
records show that you are the owner of one of these vehicles.
What Is The Problem?
The electronic control module (ECM) software for the catalytic converter monitoring system is too sensitive. This can cause the
MIL to come on, and some vehicles may exceed Federal and/or California emissions standards and may cause the vehicle to
fail an emission inspection or I/M smog check test. Also, in some cases this leads to unnecessary catalytic converter
replacement.
What Will Volkswagen Do?
Dealers will update the ECM software. Your eligibility for vehicle inspection/repair under this action may not be denied solely
on the basis that the vehicle or engine owner used parts not manufactured by Volkswagen, or had repairs performed by outlets
other than an authorized Volkswagen dealer.
What We Would Like You To Do
Please contact your authorized Volkswagen dealer and arrange for an appointment without delay. This service will take less
than one hour and will be free of charge. Please keep in mind that your dealer may need additional time for the preparation of
the repair and to accommodate the daily workshop schedule. In order to assure your full protection under the emission
warranty provisions, it is recommended that you have your vehicle serviced as soon as possible. Failure to do so could be
determined as lack of proper maintenance of your vehicle.
