I have tried 2 different companies with 2 different aftermarket filters. The drier side pump filter throws a P2540 code is saying it is a low pressure / performance issue measurements are outside the norms. The lo pressure fuel pump works perfectly


Has anyone had Experience with using aftermarket fuel filters? have a hard time believing that a new filter would cause these error codes


I have replaced both fuel pumps on my E class that is throwing me for a loop after installing the new driver side suction pump/ filter assembly I am getting a pending P2540 when ever the driver side fuel filter suction pump is installed.
