Good morning everyone I went to a garage because they had a golf 6 1600 tdi year 2010 cayc engine that after replacing the diesel filter it wouldn't start anymore they told me that reading on the various forums it was enough to insert the ignition and the car would start but this wasn't the case.

I hooked up my diagnosis and went into engine electronics with the car in question, then to activations and to electric fuel pump relay run activation this loaded the system and the car started immediately, most likely after the replacement the system was emptied by this operation if it is reloaded.

Good work to all.

Claudio.
