Right, just swapped over dashes, recoded, immo PIN entered correctly and accepted by new dash.
Engine starts and all is well.
I'm just getting low washer bottle and blown head lights and brake lights.
By my reckoning i need to ground pins 15 and 16 in the 32 pin grey connector.
Anyone confirm?
I'll live with it for now because i've still to retro RNS-D with TMC module yet.
