Right Here goes took one of mine out in the end to get the pics and the damn Part Number..This is how yours should look(fig 1)You will have to take both Rail-Stoppers off the back of the Seat Rail see fig 4 and fig 5 it's just a Phillips screw holding them in..
There is a one inch long square metal spring piece(See fig 1) at the front of the bar you will be able to see it in the pic just get pliers on that and pull it out otherwise the seat will not go back..
Pull the lever to move the seat just slightly back so you can get at the place where the Glide(that is what it's called)as to be fitted you will see from fig 2 the seat pulled back and how your's will now look with no Glide fitted..
Right now get the Glide(fig 3) and fit it in the top there is a hole in the top as you might be able to see from the pic and a protruding bit on the glide that fits that hole..
When you are happy it is in properly make sure the seat at the back is in contact both sides on the rail,here is the hard bit took be about half an hour to get this ****** thing lined up properly you pull the lever back and it as to fit in the bar at the same time and you have to pull the seat forward also, and line the hole up and it will trap the plastic Glide as it comes forward..
This is when you might wish you had not started this but it's ok just persevere you will get there in the end..I did wonder if I was going to get mine back in again and thought why did I create this problem..when done put the stoppers back on the rails at the back and jobs a good un..
Good luck if you have a problem let me know...you need 2 Glides to do both seats obviously part number is there in pic 3, I had a nightmare trying to read the number I had to get magnifying glass on it..
Should be Pennies anyway from Audi...Your Seats will Rattle no more :icon_thumright:
These are the pics to help you know what I have been saying..
