Default E89 Z4 BEF 29F3 Code - 06-22-2018, 03:03 PM

I am running into a situation with a BMS BEF for a 2012 Z4 with an INA0S software. After flashing the car keeps looking for a low pressure fuel sensor when this doesnít have one, throwing a code 29F3. Is there something I need to turn off when I flash using MHD? Any help is appreciated. If you have any pointers Iíd greatly appreciate it. Load a different software version maybe?

Also, are there any ways to load the GTS transmission software into a Z4 DCT? Solutions like MHD and the like? Much appreciated for all the help!

Can you get a log or screen shot of the code? Does it automatically start up with that? MHD is dummy proof so you can't really load the wrong flash per ecu.

Immediately after flashing the car with either Stage0 or with any of the posted BEF on the main N54 thread, the car once started throws a check engine light and puts the car into limp mode. The following screenshots of what was flashed and the codes pulled up:

PS: Also tried to use the MHD Stage 0 where it leaves MHD installed at stock power levels and it did the same thing.

Best would be to email MHD directly. From what I see it looks okay, but no idea why the car runs like that after a flash.

I wanted to keep anyone who search this thread in the future informed in the event they run into the same issue, I got to the bottom of the problem.

@Payam, I did contact MHD based on your advice. MHD made the recommendation, since this is an E89 Z4 35i and not an iS to use the IJE0S bin files to flash. Even though this car came with an INA0S SW. This flash made everything work, it still has the 29F3 low pressure sensor code in the DME but it doesn't set a check engine light which is perfect.

Thanks for the help.

Wow nice man, that is very helpful and I'm glad you posted that. So it was an Ijeos bin that ultimately worked?

I have the same problem. I'm using the latest IJE0S_RACE.bin file. I was already ordering a low pressure sensor but luckily i didn't. It would be nice to get rid of the 29F3 code.

Itís possible if you have access to Tunerpro. Just download the XDF files and you should be able to turn that code off.

What value should I enter to turn off the sensor? Is the picture right? I'm trying to edit the E85 map ..
