2004 BMW 530i Question: Replacement cost for fuel pump and oil pressure swith

 

Question

Car stopped while driving on freeway Xmas day. Will start (sometimes), runs for a second and stop. Towed to dealer, they replaced fuel pump($1500), now says they need to replace oil pressure switch ($550). Does this sound a bit high for a oil pressure switch. Also, sounds like maybe the feul pump may not have been the problem after all. (help)

    John,
    If my vehicle didn't start and a shop recommended a $1500 repair that didn't fix the car, then I would be very upset. I don't know the whole story here, but if the exact problem still exists after replacing the fuel pump, then they have some explaining to do.
    Can you state what they said was wrong with the fuel pump and what the issue is now? Are the symptoms the same?

    Got the bill for $1961.81 and it states the following;

    "Faulty fuel pump and fuel filter. Interrogated fault memory. No relevent faults found at this time. Checked fuel pressure at fuel rail. Replaced fuel pump and filter assy. Started car and let idle. checked fault memory. No faults found. Shut off car and would not restart. Interrogated fault memory. Found fault for CAS terminal 15. Checked connection at CAS module. Checked connection in E-Box from CAS. Found Oil Level Sensor shorted and causing voltage drop from CAS unit. Replaced Oil Level Sensor and installed updated harness."

    I'm not sure what all that means but I have this bad feeling that I may have just got taken advantage of.

    A double failure like that is possible but not likely.
    I request the parts and received the pump and filter but some how the oil level senor got discarded. Yea Right!

    I'm still in a daze and not think well. Will check out pump and get back with you.

    Thanks for the feedback

    John,
    There's something missing here: "Checked fuel pressure at fuel rail. Replaced fuel pump and filter assy. ". They checked the fuel pressure but don't note the fuel pressure reading, and if there wasn't fuel pressure, they should've checked to see if there was power and ground signals to the electric pump motor.
    It all sounds fishy, let me know how it turns out, and when it's all done, please review this shop in our shop directory so others can hear about your experience.

    That's what you get for trying to be British!

    BMW = Bayerische Motoren Werke AG, (literally English: Bavarian Motor Works) is a German automobile. But I get your point.
