2007 E60 535d - INPA Problems

[modified]

Hi Guys, Im new to the board and like some have got some intermittant boost problems. i get no power up to the redline and then when the gear changes up i get full boost with no problems...it come and goes but is really annoying....i'd like to check the error codes to see if i have dpf or actuator probelms....Ive managed to get a hold of a copy of INPA dis etc from a company called David wragg Holdings. I also have i believe the correct ediabas obd to usb lead. ive loaded the software correctly i believe, but looks like the software works with a serial connector as the ini file configures com 1. Does anyone know how to get it to work with the usb. When i look in device manager the usb connector is showing a fault and is not installed. Birmingham based Many Thanks ali

You can change the port allocation to com1 in device manager, or edit the Port=Com(X)
in C:\EDIABAS\Bin\obd.ini to suit your cable com port allocation

this is my obd.ini file...does it look right? I dont have a serial connector on my laptop so do i have to configure the obd.ini to look at the usb connector instead? many thanks

go to device manager and plug the diag lead into the usb port, the list will update and show what port is allocated for this lead,
then follow post #2

binman's thread will probably help explain and visualise ..INPA OBD2 USB Interface review

Ok thanks for the info so far.... The problem I have is that the cable itself won't install as when I plug it in it tries to locate the drivers for it. However it doesn't find them so in device manager it lists it under other devices as not installed. This
Means it doesn't show on ports menu so I can check what com has been assigned to it. Is there a driver for the obd cable? Thanks

Try the Prolific PL2303 driver.

I'm guessing the lead I have is the wrong one. Is there any way to confirm the type of lead I have?

well sucess at last. I couldn't get the cable to interface with the laptop..... after some reading around i installed a virtual com port driver from here
http://www.ftdichip.com/Drivers/VCP.htm

i installed the drivers and plugged the usb/obd lead. The pc picked up the lead and installed the lead without any problems. i then check in device manager under ports and found that the pc had assigned com port 9 to the cable...i then modified the obd.ini file and changed it from com 1 to com 9. inpa now works and both circles go black.

however i can get any information from inpa regarding faults...will have to find out how it works....i managed to get diaghead and dis to work as well.....thanks for the help. ali
