E90 inner brake light issue. Coding?

N52bigblock · 02-15-2019, 12:04 PM

Hi Guys,
I've only just discovered this part of the forum. I'm in New Zealand and wasn't aware there was an Australian section. I posted this thread in the main forum so thought i would repost here to see if any of you could help me with this one possibly.

I have noticed on my car that only the outer brake light works on both sides. No CC faults, no faults stored when i scanned with ISTA. When i activate the brake lights via the ISTA test module, both the inner and outer lights work (as i think they should) I have checked 3 other E90s and they are all the same, only the outer brake light works. I am thinking this could be a coding issue forthe Japan region? My car is a Japanese import as are most cars over here.

Wondering if one of you guys could have a quick check of your pre LCI E90s and let me know if yours is the same? Then maybe we could compare FRM.TRC files. I had a quick look at the FRM.TRC files and found RL_L_ BREMS_ FKT and changed that from not active to active but that didn't do anything. Thanks heaps in advance.

Managed to rectify this. Both lights are working now. It was a coding issue. Changed values with NCS Expert.

What values did you change? You posing the changes could help someone in the future.

It would be the parameter along the lines of "brake force display"

ie. the inner globes only light up once you generate a certain pressure using your foot.

Well since I'm a sharing and caring Kiwi I'm more than happy to share what i changed. First i made a copy of my original file in case a f'ed something up. Then after a bit of trial and error i found it was the BFD_BREMSL_FKT changed it from NICHT_AKTIV to AKTIV

If I'm not mistaken, my car doesn't have the brake force display. In my options list i have this option S5ABA Twostage Stoplamp Discontinued.
