There should be a matching 6577E on the top of the white connector once you open the case up if the circuit board matches the case.

yes it does this will work on my 91 tsi right? is it an eprom ?i think it is but im new here.

If the connector says 6577E then there should be a large rectangular 28 pin chip with E931 printed on it. Installing a 1k 1/4Watt resistor at R129 wiil make it a Federal ECU.

With the resistor installed it will work in your car without throwing a EGR CEL.
