    Hi,
    I have been getting these errors when trying to read the lambda data on my car (see attached pics). The error happens when the car is running and when it is off.

    I am using a modified VAGCOM USB cable with pins 7/8 shorted, INPA 5, using Joy's install notes. All other data and faults can be read and cleared.

    Any ideas?
    Thanks

    What are your settings in OBD.ini and Ediabas.ini?

    Try
    obd.ini
    Hardware=USB or Hardware=OBD

    ediabas.ini
    Interface=STD:OBD

    Also did you skip the step where you set all the FIFO buffers etc in the registry? If so, go back and perform that step.

    This is common if you have loaded the incorrect module, for example chosing the wrong engine type etc. Check you deffently got the correct engine type selected. Failing that what version of Inpa are you using???

    Ahh, didn't do that as I thought is was for E36. I will try later today.

    Clicking yes just brings back another error and then on in a loop untill you click no. Also the engine is correct, otherwise I would not be able to see other live data or clear the codes.

    I have tried the suggested fixes, but they didn't work. It just craps out when reading the second line value information for the Lambda probes.

    My car is pre March 2003 UK spec, so is only equipped with two Bosch lambda probes. One regulating (before CAT) and one monitoring (after CAT).

    Any other ideas please?

    Maybe try using only pin 7 or pin 8 for high speed Lambda sensor diagnostics. Usually these sorts of errors arise when there is a throughput issue or a data collision.

    I ususally just hold down the Y key. You only really need a could of snaphots shots at the lambda sensor at high and low volts. The baud rate is too low to get the 02 sensor curving fast.
