I have to replace ECU on my CLK230 Cabriolet. Year 2000. I’ve been told by auto electrician that I need the ignition switch key and steering lock as well as ECU. The ECU on car is a Bosch A 028 545 78 32. I can buy complete kit for a 2001 CLK230 but it is a Siemens A 111 153 07 79. Does anyone know if this will fit and work please? Thanks.
