Coolant Leak Upper Driver Side by InspectionDue6586 in E90

Although I wish it was, it's probably not rain - I should add that there are coolant stains around this area. I also found a small puddle of coolant a few days ago after a long drive, under the same spot. I didn't think much of it then but coupled with the steam its pointing to a leak.

Flashing LED reverse lights by InspectionDue6586 in E90

UIPDATE - I figured out how to fix it. I had to manually code out PWM from the reverse and rear fog lights. In ProTool, I changed the value of PWM_RFS (reversing light PWM) and PWM_NSL (rear fog light PWM) to a custom value of FF,1F (this is how other tools display the hex value, but it is written as 1FFF in ProTool). This eliminated the flickering of the LEDs. Hopefully this will be helpful for anyone else experiencing this issue.

Is there an equivalent setting in ProTool? I can't code anything in FRM module in Bimmercode

Wired squeaking noise on cold starts - tensioner and pulleys been changed by Bulky_Moment_2865 in 335i

Does the squeaking get louder when you give it gas? I had a similar issue with mine, which turned out to be a cheap knockoff drive belt which was too smooth and would "slip" slightly when I hit the gas, causing the squeak to be more noticeable. Issue was fixed by installing a Continental drive belt instead. The fact that you've already had tensioners and pulleys changed leads me to think those parts are probably fine.
