Default Trim 25 - 09-15-2019, 01:31 PM

Hey guys,

Long story short, my 135i broke down 2 weeks ago so had it towed. Got limp mode on a 2nd gear pull, put it in neutral and the engine stalled and never turned on again. The next day the shop where I brought it (a very reputable BMW shop in my area btw) started it (wtf) and told me there was nothing wrong with the car. The steering wheel control for the JB4 didn't work when it happened.

This made me take some logs to see if I could find something but I'm a rookie at this. I know trims should not be stuck at 25 but I don't know if it's really bad or not given it's always the first 500 rpm of a pull that does it. Here are some logs I took on map 1 and 2, but I accidentally lost the map 4 one (it looked exactly the same anyway). I chose the 2 that looked the more accurate, but every logs lare pretty much the same. Running on 91 oct

So 2 questions:

1. Could my issue only be the JB4 going to the end of its life?
2. Should I investigate on something or my logs look good?

BTW I have a k+dcan cable in the mail to do a BEF if this can help.

Thanks in advance

Not fully clear to me what the issue is exactly? Logs seem fine.

Wondering if the afr going up and down at the beginning of the pull and trim flat at 25 is normal? I couldn't get the engine running at a red light so I'm trying to figure out what's wrong so it doesn't happen again... I suspect something bad with the jb4 since I couldn't enter the dash controls when it happened
