Hi,
have same problem with E210 diesel 2001 with automatic transmission - EZS 2105450208 Q4

Read cpu1 but get all FF.

Read cpu2 and copy to cpu1 but ezs is dead - do i need to make new key?

I have another EZS with same number but Q6. Virgin ecu code with star, but now gear box did not change gear.

What's wrong?

Regards
Mat
