Hi there. I have a 300TE that the local dealership says need a new ECU. At first they thought it was the 02 sensor so I replace that but I still have a rough idle. I searched around here and found that my OVP might be busted too but I checked the voltage on it and it is fine.

The local mercedes dealership says I need mercedes part number 011 545 28 32 but my car currently has mercedes part number 008 545 82 32 / Bosch #0 280 800 322. Maybe they are compatible?

I have looked around on ebay and there are a few other replacement ECU's that sellers claim will work with my car including Bosch #'s 0 280 800 256 and 0 280 800 450.

Does anyone know the Bosch #'s of compatible replacement ECU's for a California model 300TE?

Thanks.
