I posted the following to the Jeep ng, but folks there don't really know
much about the CRD Liberty or diesels in general. Since I have such
great success with getting answers to my Ram CRD questions in this ng, I
thought I would ask.
2006 Liberty Limited 2.8L CRD. The maintenance schedule says to
"inspect and replace as necessary" the boost pressure solenoid air
filter. I thought that perhaps this was just a fancy way of talking
about the engine air filter.
Apparently, these are two separate filters since they are mentioned
separately in the maintenance schedule, one right under the other.
I looked up boost pressure solenoid air filter in the FSM and it doesn't
say a damn thing about it except that a clogged one might cause boost
Anyone know what and where this filter is?
