thanks for the quick reply.
no i didn't enter any txt, i don't know how to do it...
i entered the audi a3 chassis and searched for the diagrams normally.
then i searched for the golf model manually by category and year, and as said above when i entered the table code of a car, while i was in the other, this error was generated...
maybe because the table/drawing number of a car doesn't correspond to something in the other car.
i thought i would do it first to skip between the two, instead i made a mess...
in short no, i didn't enter any PR or any other code... i don't know how to do it...
do you know how i can restore the correct functioning?
