Can anyone tell me the easiest way to connect to a Bosch 0281 001 224 ECU running (so I'm told) MSA11 7.9? Before I go attempting other more inventive methods, I thought I'd check there isn't an obvious way first to access the error codes. The problem is that the ECU is on an older motorhome, and (wouldn't you know it?) neither Fiat main agents or Bosch service centres now have the correct gear to connect up.

TIA ...
