I have a 2005 Jeep liberty w/ Diesel engine. With constant problems 2009.
They replaced EGR valve under code PO401 in October 2009 and again w/ a new Turbo in July 2011 (not sure of code). Currently has fault for low boost pressure. And they found very small leak from small crack in throttle body.
The Dealership says that because of the flow chart they are unable to determine if this is the primary problem until they replace throttle body.
Could the EGR, Turbo and this throttle body problem be related? Or does it relate to one of the other problems listed bellow?
I feel like I am chasing my tail.
How can I find a Diesel mechanic who works on small vehicles, but is not at the dealership?
Here is some of my 2005 Jeep liberty Diesel history.
October of 2009 Code PO 401: Changed EGR valve with improvement
November 2010 Code PO300 Changed fuel water separator and harness
April 2011. Found a Coost Pressure leak at hose Replaced Hose
July 2011 Faulty turbo and EGR valve Replaced EGR valve, tube removed inner cooler and sent for cleaning, reinstalled evac and recharged. (Dealership took on some financial responsibility for Turbo)
October 2011 They wrote “Has fault for low boost pressure. Found very small leak from small crack in throttle body"
