hi all will this ecu fit my 2000 s3 the standerd code on the ecu is 8L0906018k and the new one is 8n0906018n i no it came out of a s3 but will it fit ??
 
8L0906018k is a APY ECU

Definately 8N0 for the new one?

8L0906018N is also an APY ECU, but from a car with ESP.

8N0906018N isnt showing up for me.
 
my car is a 2000 s3 apy and the car the new ecu cam of is a y plate dont no what year this is but im waiting on the engine code
 
sorry mate its 8l0906018k is the old one and 8n0906018j is the new one
 
APY (yours) is a narrowband ECU, AMK (18J) is wideband so no... not a direct fit..
