Question about BMW Z3

1 Answer

I have a 2000 BMW Z3 ROADSTER with a 2.5 6 cyl. Computer code was showing a defective cam shaft sensor circuit 1.During testing of the sensor,ohms and volts,the engine will now not start and all I did was disconnect the connector to test with. before that it would run, but would hesitate and stall at stops,sometimes it would take a little cranking to get started. I have installed a new cam sensor and still have no start.ohm meter showed a good ground continuity and i have a 5 volt reference from the computer.where do i go next

You need to do a cmp/ckp relearn
however, you will need a scan tool to do this
look in your yellow pages for a mobile technician
this is someone who will come to you house
this might cost a few dollars more than a regular garage but you'll save the $50 in towing fees

    unfortunately...
    1.) I don't have or know your scan tool
    2.) I don't have a 2000 BMW in the shop right now
    3.) My service data only shows computer relearn procedures by driving the vehicle

    best I can do is to tell you to search your scanner under the PCM tab for CKP or CMP relearn


    sorry I could not be of more assistance

HELLO, I HAVE TROUBLE CODES PO330,PO340, ON MY OBD2 READER WITH THE MAINT LIGHT ON IN 96 BMW Z3 ROADSTER 4CYL., PO330 IS KNOCK SENOR, PO340 IS CAMSHAFT POSITION SENOR, I WANT TO KNOW HOW TO FIX THEM BOTH....


The Cam Position Sensor is a common item to fail. However, the cam positioning mechanism can fail too giving that code.

There are two sensors and the Exhaust Cam Sensor is most common to fail. I always replace both.
Te CKP's are on the top front of the engine next to the cylindrical operation solenoids.

Knock sensors fail too and need checked or correct feedback to ECU with a scanner.
Find a shop near you at http://www.iatn.net/shopfinder/

These engines require regular oil changes with quality synthetic oils and OE filter....not a FRAM or WIX !

Buy only BMW sensors ...aftermarket have high failure rate.
