Congress passed this act which requires that certain new cars and their replacement parts be marked in a way that would prevent theft rings and chop shops from disposing of parts easily. The act is administered by the National Highway Traffic Safety Administration (NHTSA) and the manufacturer certifies compliance by means similar to the safety certification.
The marking begins as of
Production Date: Sept. 1, 1986.
Porsche models involved are:
911 Carrera 911 Turbo 928S4
Parts to be marked are:
Bumpers - front and rear Fenders/Quarter Panels - front and rear Doors - left and right Hood and Rear Hatch Engine and Transmission Housing
The marking and their location differs between "Original part on new car" and "Replacement part". Refer to pages 2 to 9.
All original parts show vehicle VIN. Replacement parts show the symbol
on a special label with a clear plastic mask. It is the dealers' responsibility to remove the clear plastic mask from the label after painting or undercoating the replacement part so that the marking is clearly legible.
Factory rebuilt engines and transmissions utilizing already marked housings won't have new markings.
When replacing marked parts dealer may use:
1. Marked Porsche replacement parts
2. Marked after-market parts
3. Unmarked Porsche parts which were in stock before April 1986
When repairing marked parts the original markings must still be legible.
When installing unmarked replacement parts from dealer inventory, marked parts from another car or rebuilt engines or transmissions on marked cars, the dealer should provide the customer with detailed documentation, e.g. explanation on Repair Invoice.
This law also applies to U.S. tourist vehicles repaired outside of the U.S.A.
