    hi
    i have s s320 cdi, and engine ecu is water damaged during car wash, as unfortunately fusebox lid wasn't locked poperly. mechanic opens the ecu and the ICs on the circuit board are melted, its clear that ecu is not repairable

    now mechanic says to get Ecu, ignition switch and key from same car. but one car breaker told me that it wont work even if you change these things as still they need to be programmed with i think ... gearbox ecu, vin no....etc
    he told pre facelift ecu's (613---)are simple just change ecu ,eis and key , but on face lift models they need programing ecu no. A648-------

    sorry i dont know much about this, i just bought the car and next day this happens. i cant afford expensive repair so i dont wanna buy parts and then if it wont start then mechanic says sorry i dont know...

    i really appreciate, if someone tells in detail that what exactaly need to change(i mean ecu ,eis and key is enough or need something else) or if someone alraedy had the same propblem and fixed that

    thanks

    W220 has shift lock.

    Just get an Ecu and have it programmed!
