Multi Function Switch
My Audi (A4 1997 Quattro 1.8T automatic) went to LIMP mode recently. Reverse does not work. I took the car to an Audi dealer and they told me Multi Function Switch should be replaced. I am confused on the part#. I was reading Nate's post about replacing MFS and the part# he had was 01V919821D. Searching on the internet for neutral safety switch for Audi A4 gets me part#s like W0133-1598328, J4050-140033. I am not sure which is the right part number if I have to order one. Also is there any link between F125 and Multi Function Switch. Any help is really appreciated.

01V-919-821-D is the factory (OEM) part number. I have no idea what those other numbers are.
Buy it from here: http://www.genuinevwaudiparts.com/pa...?siteid=214407

Is there any link between F125 and Multi Function Switch? I am asking this question because the note i got from the dealer who inspected my car says, "Needs replacement of Multi Function Switch (F125)" .
Here are some other sites I found the Multi Function Switch? Are these the samne?

Yes, that is the right and same part on all counts. But with it being $360 from a DEALER, why would you bother with those other two places? That's why I provided the factory PN for people who need it.
Screw Shokan, I will *never* give them my money.

It's a very common failure. There is no "cleaning up" of the device, look at my post right below the FAQ entry inside the MFS. You'll see why.
You need a VAG-COM to reset the trans codes. A generic scanner will not be able to clear it and the TCU will not function right until the code is cleared.
I think disconnecting the battery for 10 minutes might work too.

Before going too far, have you cleaned the connections? This is often where the electrical problems really are, and putting on an expensive new MFS will just get you a clean set of contacts. The insides of the MFS is a group of common micro-switches, which are usually sealed and reliable. The connector, however, is kind of out in the weather. Try disconnecting, then spraying WD-40 or contact cleaner in both sides. I had the F125 code, and after a connector cleaning have had no further problems with it.

I second this, but don't use wd40, use contact cleaner. It is 3 dollars a can from ACE Hardware. Also, DO NOT pay that much for a switch. The neutral safety switch is WAY cheaper from us than the link you posted above. Just pay attention to your VIN when ordering. I can help you with that if you need.

Can somebody explain to me how the MFS can cause this issue?
