I am trying to get a mass air flow sensor for my car. I called audi and they said the part number is 06A 906 461LX i CANT FIND ONE WITH THAT CODE ON EBAY THE ONLY ONE i CAN FIND IS O6A 906 451L. Is there a difference between them, can I use the L one or do I need the LX one. Thanks JAyme

O6A 906 451L does not exist on Etka. Contact the seller and ask him to check the part number or tell you what make and model it came off of.
