Insert key and turn it on - off - on - off - on at max 5 sek or something like that... than the car shows it error codes by *blinking* with checkengine lamp.
*blink* *blink* *blink* *paus* *blink* *blink* means code 32
you can find the codes at internet... or in the haynes service book.
It can be a sequens of more codes like 47, 32, 11 so you just have to test a couple of times.
I think code 55 means ok but im not sure... it works at my -95 Gr.Voy and i think it should work at yours too...
