Cannot connect to OBD?

[Tommy10]

For my F15 2015/05. -Just bought an X-Bimmer Wifi Enet coding adapter and trying to connect to ISTA+ but seems to not be working fully. Tried both via wifi and ethernet cable. I used the ISTA+ 4.39.20 one click installer, firewall off, starting ISTA as admin. I check the Administration/preferences: dealer org. icom/Enet Lan. ”Ethernrt as preferred communicstion channel…” set to No.

Trying to connect and it seems to find the VIN in the ”Connection Manager” window. But when pressing ”Set up connection” nothing happens. Also tried to manually insert my VIN but a window appear saying ”Error - The VIN entered is not valid and/or not assigned. Re-enter the VIN of the vehicle”, but nothing happens. However one time when trying to connect I got to the window where the it reads out the general info, but instead of showing my info in the ”Vehicle details”, there’s just yellow triangles with exclamation marks.

I tried to connect to the BimmerCode app (not paid) and it can read the spec of the car, but when trying to press any or the ”Control Units” it says ”Error while reading coding data”.

I figured there might be a fuse for the OBD connector but when trying to find which one on forums it seems it’s in the BDC, #11. But its shared with Hearing/Air conditioning system and DSC. But I believe I would have known if those didnt work.

PLEASE, Any suggestions?

Uploading a clip from ISTA+.

No one?

ISTA doesn't support wi-fi adapters, you need enet cable to connect.

Thanks, thats good to know! Will try using the ethernet port as well tonight. Will update after.

By the way, as far as I umderstood from the Ista manual, I’m supposed to be able to use it offline without connection by just inserting my VIN, but that doesn’t work either. No info pops up, just a loading screen for 0,5s and then the same window. Any suggestions? I installed ista 4.39.20 with one file installation, excl the programming files which was an option in the installation process.

If you installed everything correctly and you have right e-net cable it should establish connection to the car automatically and offer your to scan. This is my settings page for enet connection, I think this is default one.

Actually you can, that's how i connect mine. I use the modBMD adapter tho.
When you connect your laptop to the adapters wifi, check what IP you get. It should be a 169.254.x.x

I think RED has a newer version of ista, mine doesn't have that middle option he uses. Mine is set to Local network (top option)

*EDIT*. No dongle.

Thanks a lot. Last night I gave it another shot without success. However slightly different input:

I found in some previous post that I should run the "ISTA_Reg_Fix_x64" and another one (cant remember it's name but something like "use_only_if_SDP_NOT_installed", which I did and restarted the laptop.

I tried using ethernet cable as per the instruction, setting its IPv4 adress to 169.254.1.1, subnet 255.255.0.0. Disabled the Windows firewall. Plugged in the cable in the car and pressed the start button. Started ISTA, tried first with Interface type "ENET Local area network": Then operations -->Read out data --> Complete identification, but nothing happens, it just shows a loading window for 0,5s and then nothing happens.

I also tried Interface type "ENET direct connection". Went on to Operations--> New and Read out vechicle data. In the pop-up, no ip adress inserted, I chose interface "ENET" --> OK. I then get a message saying:


Ediabas file says "Interface = REMOTE".
I use Win 11 Pro

What I now could do was tro insert the 7 VIN characters in Operations and I could at least check the "Workshop/Operating Fluids". Not sure this was possbile prior to yesterdays attempt.

As a comment to the possible Wifi support, when I tried it last Sunday with "ENET Local area network" --> Operations --> New --> Read out vehicle data --> Complete identification. The Connection manager window appear and I can see my VIN number, so it seems to be communicating. I choose it and press "Set up connection", but nothing happens except that the window closes and I'm back in the Operations--> window as if nothing happened. No VIN or vehicle is shown. Note, not sure about the IP adress shown in the connection manager, should it be changed, if so where? Windows network settings as with ethernet?

Any suggestions?

ISTA supports wifi adaptor. I use bm3 w/o any special setup.

Ok thanks, so no special IP adress setup or similar? Nothing in Ediabas that needs to be changed? thanks

[m4forum]

nope.

The wifi adapter is just that a wifi adapter, just like the one for your internet in the house.

Base on your screenshot, the wifi adapters gives out the 192.168.x.x IPs. So leave your wifi settings on laptop to DHCP/obtain auto. In ISTA use the ENET, LAN option. You should need to disable the Firewall, but if you are going to. Disable all the profiles, inc domain.

Don't connect your laptop to both WIFI (house) and ENET cable at the same time. That may confuse it.

When you press the setup connection, it should start scanning. Maybe you've messed with it a bit too much. Is this on a VM? Clean up and try a new ISTA install?

Thanks, I have just reinstalled it completely but haven't got the chance to test it yet. This time I choose the complete installation incl. programming. Let's see if there's any difference. One thing that might be different from the first time is that I suspect that 7-zip wasn't the used program last time, but windows built in.

By the way, without the programming part, is it still possible to do diagnostics and fault finding/live testing with the vehicle? I also want to install E-sys, but I don't have enough free space for both the full programs. Also, do you see any possible issues with having one of those programs installed on a drive made of an sd card and formated as NTFS?

I dont have programming and can use all the ISTA+ diagnosis capabilities including live measurements.
The smart way to do it to share the same psdzdata. Watch the video below.

Great, thanks!

Update: with the reinstalled (full) ISTA it is working👌🏼. Either I’ll use above suggestion and share the psdzdata files or reinstall for just the diagnostics (maybe esier for my limited usage of programming part), maybe I did something during my first installation so it didn’t work.

However, one question with only ISTA diagnostics installed, is it possible to initiate functions, -i have a fault code for the PFD to be renewed soon and I understood that I can actively initiate the regeneration function. But is this possible with only diagnostics installed?

Also, another problem I have is that the Nav. Professional gets stuck at the losfung page when pressing the Nav button. I’ve understood I should try to flash it in Esys, but are there anything similar I could first try in ISTA?

I believe it is important to understand what programming is. Programming means the SW currently on ECU is replaced with a new SW version. OEM release new SW when new functions are added or bugs are fixed.
ISTA is a diagnostic tool which can have the programming capabilities in case full database is installed. Diagnostic procedures dont require any programming as they only read/write values from the ECU but them dont change how the ECU process inputs.
Regeneration is available for DPF.
I suggest for the DPF to check flow resistance diesel particulate filter (mbar/m^3/h). Needs to be lower than 0.25 at any condition (unloaded or loaded). If this can be confirmed just run the ABL for DPF replacement and your DPF will run more 150k mile ... wont need to replace it. But in case value is higher than 0.25 need to clean it.

[Tommy10]

Great input, thanks! Will check that.

I'm preparing myself by checking youtube videos, but tI don't see anyone check the flow resistance, everyone seems to just check the "ABL - Exhaust gas pressure sensor". Where it tests the resistance at 2000 rpm and a max value of 75and then at 4000 rpm. Should be below 75 mbar and 35 mbar, but that's not the same?

check if not under OBD expert or just measurement under DDE on control unit tree
