Can anyone shed some light on this fault? the led in the dash is flashing 22 I've tried a known good pcm and pats module I've tried deleting keys and recoding them ive checked power and ground and can wires at fuel pump but still no joy it's the 1.8 tddi engine

If the battery has been flat or you have cranked the engine over with a flat battery then the most likely cause is the PCM and the FIP have lost their synchronisation

Make sure the battery is fully charged, jump leads on another car are not good enough as you need a good steady voltage, then run module initialisation in IDS and the engine should then run.
