Hello ,
 
If you have an 2001-year car , front-wheel drive , and you installed an S4 B6 quattro km/h cluster gauge , everything  will  work except fuel gauge  , to everything to  work properly you must first take a  code from a car  from at least 2002 year (fwd or quattro , does not matter) , from km/h clock or ECU of that car ,  don't know what code  , anybody who knows  how to work with VCDS  must know .
 
Then change the code in keys so that you can  start your car ,   you need a small plastic thing , don't know how its called, but it is few euros , i needed tree ,  he had two , bla bla  ,  so  , two keys work  , one need it to be coded now he don't know when he will be back in Croatia , same old story you know it .
 
If someone have a link where to buy that little plastic thing , link would be appreciated to me and others know .
 
PS : your non-coded  old  key will work, you can start a car, but  only it will run  for one second , you can lock and unlock the car.
 
So you need at least 2002 y . quattro  fuel pump  component( fuel level guage ) , full pump it  self can be from your car and can be from a big range  of cars , maybe it will work with just like this fuel lever component  in the picture below from at least 2002  quattro , but the price is or little less then a  who'll set , so not wort it .
 

 
 
I did buy exactly from this store ,  this link below  , part number to just be 100000 % sure was 8E0919051CJ
