Brakes applying themselves
Good evening Hopefully you can advise me, I have a 2015 (facelift) 1 series , last week I was driving and the brakes seemed to apply thereselves, slowing the car right down. After pulling over and waiting a while it drove fine. Then a few days later happened again with a burning smell from front left I took it to the garage and they said a stick caliper, they also replaced disk and pads As well as calipers. I picked it up £790 lighter and its happened again. I'll be calling them first thing in the morning to see what they say I've done the basic servo check, engine off pump break until hard, start engine and the pedal releases so surely this can't be the servo. Any ideas at all? I'd like to speak with them having a little knowledge many thanks in advance Mark . -

E90 320i Help With OBD II Port
Morning Tino My copy of INPA/ISTA worked straight out of the box (lucky me) it runs on a Win7 laptop that I already had Merc Star, Volvo, Toyota/Subaru, and a couple of other Diagnostic progs on. However one of our sons friend has a 1 series road car and a 1 series Drift car he was always here or borrowing !! Finally he has brought his own 😁 his copy runs on Win10 laptop we downloaded a Virtual Machine loaded Win 7 then followed all the directions but it took 3 attempts to load the Drivers. With his copy he has 2 Com leads one Yellow Ethernet that is for ISTA a Silver USB lead that has the 3 position switch that one is for INPA and is where we had problems with Drivers I have mailed James he has put a request to the Techies in Germany fingers crossed they get an answer. His first thought is a Can bus issue as he says normally they work unless something physical is broken (a wire or pins) Dave P.S. I only use the Ethernet cable with mine as ISTA seems fine being backwards compatible -

E90 320i Help With OBD II Port
Hello again Dave 👋, well, as of this time I'm still having issues establishing a connection with INPA. I'm certain I have everything on the laptop setup properly. Adapter is set to COM1 and latency is set to 1. I'm wondering if maybe the driver is the issue? I was told that the resistor is a "terminating resistor". It seems each device (and the OBD port qualifies as a device) has to have a certain resistance across those CAN lines. So I don't think the wiring is causing a communication issue at this point. Wiring is factory and should allow for communication with INPA at the very least. The adapter I have does have a 3 position switch, and to be fair I only tried two of the three positions. I'm heading back out to the car now and I'll attempt establishing a connection through INPA one more time while moving the switch between the 3 positions to see if any one position makes a successful connection. I'll come back with results on tha. I'm still wondering if the issue is the JBE module or some other module that is causing the communication issue, but how exactly do I test for that? If your ex neighbour could assist that would be amazing! I really appreciate it Dave 🙏 I'll attach the adapter settings in case you want to look over them, as well as the adapter switch and wiring. -

E90 320i Help With OBD II Port
Morning Tino INPA/ISTA should recognise Chassis and ECU data and harvest it automatically, well mine does. I get Chassis information, Engine and any history recorded Just sitting with a Coffee studying the wiring diagrams up to 2007 and 2007 shows a resistor symbol in connector X13376 at Pin 1 Green/brown trace 2007-2009 shows no resistor symbol anywhere X13376 connector appears to be part of the vehicle access system it links to the DME Pin 2 Black/green trace that is part of the Start system Later today I will try and talk to an ex neighbour who is now a senior guy in BMW see if he can find any more help Dave -

E90 320i Help With OBD II Port
Hey Dave 👋 I'm back! I'm wondering if the resistor is causing software not to be able to communicate with the ECU because the initial connection is normally established. The issue is when further communication starts then it just falls off and goes dead. Even with INPA, I borrowed a laptop with INPA from a friend that works on BMW's and it's acting strange. INPA sees ignition on all the time once OBD adapter is connected with a light on at all times on the adapter. The light on adapter stays on until getting into any sub menu. For example, E90>Engine>N45/N46. The light goes out and when entering the engine option menu I get an error "Group file : D_MOTOR. IFH-0009: NO RESPONSE FROM CONTROLUNIT. Program will be stopped!" After pressing okay it takes me back go the main menu. Also, when entering the "Functional Jobs" menu, and trying to enter the E90 menu I get the error "Language variants do not match. Malfunction possible!" After pressing okay it takes me to the E90 Menu under functional jobs. When I try to press on identification or vehicle data I get the message "no response from the control unit." I want to note that whenever I enter a new menu the adapter light blinks rapidly for a few seconds like it's showing me some type of data communication is happening then it just stops. I'm wondering if the settings of INPA need to be configured a particular way in order for it to communicate with this BMW or if a module has gone bad. Hmm, maybe I need to test the resistor to make sure it's fine. Maybe just get rid of the resistor all together? I'm not sure what it's purpose is but if all other E90's can operate without it then I'd imagine it'll work without em as well but not gonna jump to any conclusions yet.
