I took my 06 E350 to the dealer for oil change.. They called me up and suggest to get the air engine air filter and cabin air filter replace as well as flush the brake fiuld. It costs around $460+ ,... Outch !!!! I can replace the air filter and cabin filter myself... Anyone flushed the brake fluid yet ??

 

E350 alldatadiy.com for the diy you will need a pressure bleed system.You will need to deactivate the sbc if your model was one of the cursedely equipped.
