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 three , 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 to 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

I did buy also JP group new rubber seal (it is Danish it should be good) install it myself , and when i did give it a contact it works , no more reserve light .
I fill the fuel to the top , like they suggested in directions , drive it to the fuel reserve light came back on , then fill it again to the max , just to test it to be sure . Everything works fine , no more reserve light
