Hi, I think you need to contact Dubbers1 as he was the one who provided the part numbers.
Sorry not sure if you can see that attachment, here is the link of the page i found it on, thanks.
Hi, was just looking through a topic that you replied in with a picture with part numbers for the undertray of a B7 a4, il attach the picture if it helps you remember, i was looking for a part no. for number 3 on this picture, if you would be able to tell me what it is if its not too much hassle id really appreciate it.
Thanks in advance, Rob.
