Ok, so after getting bearing job and SMG maintenance finished, I finally got the car on the ground and got it started and up to temperature while monitoring coolant temperature. Everything looks good in terms of coolant and oil temperature under high load and at idle. However, during the middle of a strong pull, I lost power.. no message or anything like reduced power, it just lost it's torque in the mid to high rpm range. Also, I had a suspicion that I was leaking oil before I had done the bearing job and thought maybe my oil level sensor was faulty (looks like it probably wasn't). I decided to put dye in the oil because I could'n't clearly see where oil was leaking from before doing the bearing job. There must be a hose leaking at the intake plenum on bank 1 based on the spattering pattern, but I'm not entirely sure. Bank 2 looks perfectly clean with no trace of oil.
I'd also like to mention that when the car was running at idle on the lift with underbody shields off, there was no visible leaking from the bottom of the vehicle. Also no leak visible from sitting without running.
I'll post my ISTA pictures here and post the oil leak pictures in a separate post since they're on my phone. Ignore the light module, damper control, SMG CAN faults. I ran the vehicles without lights installed, I have aftermarket coilovers and haven't coded out the error, and I believe the SMG fault is probably just due to battery voltage. Steering angle sensor may need to be cleaned/replaced (I've cleaned once and fixed the fault), but I think that could also be voltage related as well.
I appreciate all of our S85 whisperers on this forum ?.
