Fuel filter message?
 

Having 2009 Mercedes E320 CDI for the first time I want to know if this car will give any message when need to change fuel filter. It started to have a small amount of Diesel on top of the filter and also smelling Diesel when car is parked.
Any information about it?
Thanks

I have a 2008 Bluetec. I can get a check fuel filter message if there is water in the filter. Could be a false alarm due to a faulty sensor (located top center in the filter).


Change filter every 20,000 miles. Leakage is probably one of the two hoses on top of the filter. Loose clamp.

As DDAY says there is a water in filter alarm. The system does indirectly tell you when to change the filter, it is part of the Service B.

Service A = oil change + mechanical inspection
Service B = above plus fuel filter, cabin filter, brake fluid replacement. The recommended change interval for the air filter is 40k/4 yr but I think it ought to be 20/2. Problem is that if you change the air filters it requires adaptation with Xentry.
