[PedroT]

I have a vw golf 4 1.4 16v 2001, engine KO
Ecu magneti marelli

Swap 1.6 8v Audi A3 1999
Ecu Siemens

I changed the engine and gearbox, electrical installation and ECU, But he does not want to start the engine
with dash golf 4. the engine turns on if you install the audi a3 dash with the audi a3 keys

I want him to work with the dash of golf 4

Help

There's a poss chance on a Golf 4 that the immo is in the dash, if the dash is not matched to the 1.6 siemens ecu then that could be your problem

[PedroT]

the immo is in the dash, I think I'm having problems in the dash golf 4 because I think the golf 4 dash is immo 3 and de Audi a3 dash is immo 2

Try to remove immo on ecu.
