PDC Problem

[ddbb325i]

Hi Everyone,

E46 2002 325i

Does anyone have any suggestions as to what I have done wrong?

I just installed the PDC today (double & triple check the wiring).When I put the car in reverse, I just get a ring tone for about 5 seconds from the gong. Then I reverse and :( the PDC don't work.


Any suggestions??????

thanks
Dennis

Do I need to take the car to my dealer for coding the PDC unit?
