DME Compatibility on M42

[cslayman]

Hi,
I might be looking at having to replace the DME 1.7 unit (aka the engine control unit) on my '95 ti automatic. I'm not ready to do it yet. But I wanted to do some proactive legwork first.
The model I currently have is the Bosch PN 0 261 203 282. I noticed that Bosch PN 0 261 203 357 is also listed for M42 during same period of time. Are these two units interchangeable?

Thanks,
Charlie
