td5 fuel filter

anyone give me any advice on changing diesel filter td5 auto es 2002 it has become undrivable after it gets warm

Unscrew it, screw new one back on. You should then switch on the ignition, foot flat to the floor and attempt to start the engine. It may take a bit of doing, but keep the foot on the floor as this puts the ECU into bleed mode.

It pays to fill the new filter with the diesel out of the old one before screwing it on, but some are harder to start than others.
