    2002 E65 Secondary Air Pump

    Hi Guys,

    this is the second time i am posting within the last 3 weeks , unfortunately no one has replied to my initial thread .

    i would highly appreciate and be thankfull if any help or guidance can be provided

    to cut it short , my Secondary air pump wa running rough 3 weeks ago and died at the end , i have ordered new one from Autohauz online which cost me delivered to Melbourne $422 Australian dollars. took the car to my mechanic yesterday and changed the pump. This morning the pump didn't run , though the car was parked overnight and the Temp. could reach 7 Degrees night time.

    i took the car this afternnon to the BMW Goro workshop in Melbourne , they have autologic diagnostic tool where they can run component activation , they have activated the pump from the autologic scanner and again it didn't run !!! as usual they caould not find the rerason why , they charged me $66 for the sacn and they said that they need the car for a day long to dig in and find what is wrong.

    my suspescion is that there is a problem with the circuit , probably a blown fuse or relay .

    could any one who reads this post help me with finding the secondary air pump fuse and relay so i can test it PLEASE!!............

    is there any other sugesstion how to fix this problem ?? could it be the hearness

    so far i have $488 plus my mechanic fees and still did not get to the bottom of the problem

    my head is turnning around and don't know what to do

    really apprecaite if somone can help me please

    thanks in advance


    yours

    Why are you so concerned about a working/functional Sec Air pump? Do you have pollution testing in Australia? Is your SES throwing a code P0491 or 492?

    My secondary air pump problem was due to the top hose on on the air pump was disconnected. In the process of changing marker lights . I removed air filter box and right below it was my disconnected secondary air pump. Looked if it had been wet dried it out reconnected car immediately pulled a little more, still check engine light. Would reset it with obd2 reader would come back in 50 miles or less.
    Working on resting my airbag light used inpa & ncs reset whole computer and it hasn't been back scince Oct.
    the hoses runt to tThe ccv filter. Check make sure they aren't torn. Wipe oil out of the hoses if u have a little snake bush clean the out plug in ,put some chevron fuel cleaner in tank and drive the car .
    Mine was just unplugged. The P.O. had complained about this @ the dealer but didnt want them to work in it. So I think they left unplugged.

    There a grouped fusible link under the jump terminal(under the hood) if I remember correctly that powers the pump. If one of them blows you have to replace the assembly.
