Hello, I just got a 2002 A4 3.0 quattro 6 speed manual. My B6 is in good condition but the remote fob is in very poor condition. I opened it, it says:

temic-manila 115mhz
8z0837231b/35773345/01

I have seen some 8z0837231F on ebay... would it still work ending with an F instead of a B?

Is it possible to get the newer stye also?

and the last question, is it possible to roll up/down the windows from the keyfob? a friend of mine has the exact same car/year and he is able to do it!

thanks for your answers
