Good day
The Siemens Simos 2.1 5WP4459 04 ECU on my Golf MK IV failed. I got a Siemens Simos 2.1 5WP4459 03 from a secondhand parts dealer. The VW number on both these units are exactly the same.
Can someone please assist with the following:
1) Will the secondhand unit work on my car?
2) My car is manual and this unit comes from an automatic vehicle.
3) We made a copy of the file in the 93C56 EPROM in the old ECU, can I copy this to the 93C56 in the secondhand ECU or will it be better to IMMO OFF the secondhand ECU?
4) Can the SKC be read from the file copied off the failed ECU?
Thank you
