I have the part # -- what part is it?
 

Some of you saw my dealer / wire harness fiasco. Anyway, the tech jotted down several part numbers on the back of the ticket.

I have these part numbers -- example: 016 545 72 32 -- and I'd like to enter them in and find out what they are. I tried fastlane but none were in stock.

Where can I go online to look them up?
