Successfully completed proxi alignment procedure after retro-fitting electric Ti seats to 2007 159 Sedan.
After months of frustration, perseverance and various messages, from - unable to connect, proxi list in BCM empty, unstable connection, etc. problem now solved, no more flashing odometer.
Purchased an OBD-Protect interface from Fuchs in Germany. Their website claim Alfa and Multiecuscan compatibility. Arrived by mail in Australia in 5 days for $80. Not worth the hassle of altering cheap Chinese versions.
Still had problems connecting!
Cleaned up computer and updated latest version of windows, and checked latency settings in both Multiecuscan and com port in device manager. Still problems!
Re-installed com port driver in compatibility mode in device manager and bingo........connection. Proxi alignment took less than a minute.
Hope this helps others with similar issues.
