    Hi ...I would appreciate any advice. The mechanic quoted over $1,550 for the fix (EGR Valve and EGR Cooler replacement). The head gasket repair which included a lot more accompanying replacements, and cleanings, etc.. was done in January ($3,750). Fuel pump (warranty replacement), 12V battery and grounding cable replaced in May ($575).

    Since it has become a problem for me, I decided to let it go. But, how can I sell a problem to someone else? How does this work when the car has been through quite a bit of repairs that don't seem to be ending. According to KBB, the car still has value. But I'm stuck.

    ANY input is appreciated. Thank you.

    The problem is with the EGR and you need to solve it.
    On this generation, the EGR gets clogged over time and needs to be cleaned.
    In addition, there may be ongoing problems that escalate.
    Engine overheating, gasket failure, coolant leakage into the cylinders, uneven engine operation and, finally, engine seizure.
