so what can i do about this? can i buy a connection? repair it? special wires needed to repair? any help is appreciated.

Looks like an easy repair. Wires are color coded.
Only 1 small issue....is the right-most position of the connector supposed to have a wire?

Find a person parting thier 01 A4 or Private Message A4Rob (he works at an Audi salvage parts store and should be able to get you what you need). All you would need is the MAF connector then splice the new connector in. The wires are color matched, so you really can't get it wrong. If you want the best connection, you would want to solder them in. It is not necessary, but you will have a greater chance of losing volatge in the wiring (not saying you will, but you would just run a greater chance). Seal the splice with heat shrink tube and the issue should be fixed.

yea i figured the whole soldering part but just not sure on how to go about the wiring. can i just get any electrical wiring and work at it? ill pm a4rob about it thanks.

It would be easiest to purchase a pair of wire cutters (I can not recall the exact name of the pliers shaped device, but it basically removes the outer rubber sheath of the wires) or simply use a razor blade to cut the sheath off the wires. If you go to Radio Shack, Home Depot, Lowes, any autoparts store, etc, there is what is called heat shrinking tube (it is really cheap). You would cut the tube to what length you would need and slip it onto the wiring before you begin to solder (or splice). Once you are done soldering (or splicing), you would simply place the tubing over where you made the splice. Place a lighter to the heat shrink tube, and it will seal the splice to a water tight seal.

If you check back tommorow, I will take a pic of what I am talking about. Differenr wring, but all the same concept.

yea i kno how to do all that but still appreciate the procedure. im just not sure bout the wiring thats all. thanks th0

If you can get your hands on a connector that is already peiced together with wiring slack from it's original harness, then the wires should be color matched. You can't really go wrong (green to green; green w/yellow stripe to green w/yellow stripe; green w/white stripe to green w/white stripe; etc). The dealership sells connectors, but you really don't want to go that route. You have to peice it together yourself (they don't sell it put together already), it is expensive, and can be a headache. And as mentioned before, soldering is not absolutely necessary. But it is just the proper way of doing it as you will decrease chances of having a voltage drop as the MAF readings are rather important for the ECU to deliver proper fueling.

Here is a simple picture to picture step similar to what you would be doing. Make sure every wire is "color matched" to it's designated counterpart and just splice each wire one by one:

*Just wanted to add that in the pictures, I should have cut more end of the wire. When I was to bend it over then place the shrink tube on it, it should be laying on the wire itself and not the sheath of the wire because that would cause more resistance.

Edit: Out of curiosity, how did you fuber up your connector so bad? Looks like it was chewed on by a rat or something.
