06 X5 3.0i p0174 p1093

My confidence was misplaced. Check error memory and had lean code again. But watching the trims at idle was in the green, same with cruising. Idle was b1 1.5-2 and b2 2.5-3.9 While cruising b1 0.5 b2 1.2. But I noticed at idle while braking both banks jump to b1 15 and b2 being 20. Then drops to the same idle trims. So i did fix couple leaks but brakes seem to be causing another one. Is it normal for brakes to cause that jump?

Just gonna give an update. I still have P1093, but i did try swapping the O2 sensor wires for the downstream Bank 1>2 and Bank 2>1 and SES went away and no error in PASoft, I swapped them back since its probably not good idea to keep them that way. Anyway 90% sure its the downstreams like most people stated before.

P0174 is officially gone after almost 400+ miles. So brake booster vaccum was the cause. Whatever I stated above was just normal behavior of the brakes.

But bad news, I got into a nasty accident and completely destroyed the driver side fender, bumper and headlight. The structure behind the fender is also destroyed. Also both lower control arms and entire tire rod are destroyed. The car is barely worth 3 grand, so no idea if ill be fixing it. I do plan on at least making it drive-able, but body wise is in the air. Other than p1093, Engine and Transmission are healthy so I could get some money from them.

Thank you everyone for all the support with p0174!
