Hi there!

I have a problem ECU in a Mercedes W208 CLK with 3.2 engine. Original ECU is part number: 025 545 85 32. HW 39.97. FD 98M11 SW

Replacement ECU is part number: 025 545 85 32. HW 39.97. FD 98M12 SW

As the new ECU has a slightly different software number is this likely to work?

I believe I need to swap an EEPROM anyway, but I'm unsure which chip this is? I've google Bosch chip numbers but not found the answer. I found chips marked: 30132 K7843 A7857, 290836, 183060, B57554, B57943

Thanks in advance for any help!
