[offsystem]

hi!

i have problem on ducato 250 205A100 EDC17 sometimes it is not starting just cranking.

i get error Transponder compare not valid, after trying 7 times it then starts.

is this problem the read coil ? or maybe the key .

it's id46 copy the TP and you will see
If it's remote key just open it remove the pcb and put in the new TP. Temporary
