Early cars have emission data ONLY on the 16-pin in the car - all other modules must be accessed via the 20-pin under the hood(bonnet).

BUT, the 16-pin inside the car will only work if the correct cap is installed on the 20-pin under the hood (bonnet). This cap loops the appropriate data lines back to the 16-pin connector. Without this cap in place, the 16-pin connector is dead.

At least, that my understanding of how things are arranged in the early E53 cars. Later cars have everything on the 16-pin ODB port.
hey wpoll i have no clue all i know i heard all x5 under 2002 have to be scanned from 20 pin under the hood but i dont know about the emission they told me 2014 and 2016 i had it done on obd so that it had to be done the same way
