Morning kids.
Small update, havent done much to the car. but a few small things.
I purchased 2 Brand new Bosch Primary O2 Sensors (Wideband). i havent taken any photos of them so will take a few pics of the old O2 sensors when i can, they actually not bad at all.
I realised i needed the O2 Sensor socket, so contact @Bugger and he loaned me his one, so much appreciated to have the right tools (I must still make a plan to come return it bud.)
The O2 sensors were changed in under 5min, was very quick, and the car felt a little smoother, however the voltages and values when logging read the same, so safe to say the refresh of the sensors wasnt needed, but always good to have new i guess, but i have a spare set if i ever need them now.
Also i got the OEM Downpipes from @swazi85, was a pleasure to meet you man, and the F90 looks good in the flesh.

I then also tackled the disconnection of the Comfort Access handles to try diagnose a battery drain i have, after 2 weeks or more, i still have the same issue, so its safe to say its not the handles, so when i have a gap i will be reconnecting them (Yes i did clean the grime that you see there):

The 4 wire connector was for the Comfort Access, and the 2 Wire connector is for the LED Puddle Light, so quick and easy test. just finicky.
So i believe the issue has to be a forgotten Tracker unit somewhere in the car, i just need to spend some time and strip out all the engine bay covers, Footwell covers etc to try find the damn thing and remove it.
My battery health on the Bimmerlink app shows as 55% fully charged (on an apparently new battery), but within about a week, its dropped down to about 41%, and slowly gets lower.
Also, as the battery drops and gives me "Charge Battery" errors, it starts to affect the car, like causing Rail Pressure Sensor errors and then the car runs badly till i clear the error, i was worried about the HPFP going bad, but there is no way they both fail at the same time, and since keeping the battery at a decent level of charge, the Rail Pressure errors havent returned, so i know for a fact its the battery causing it.
So requirment is to buy a new OEM battery, or, at the very least, buy a new Varta AGM 105aH battery, as they are the OEM supplier. I have a First National Battery currently fitted, which i think i got screwed on. but it is what it is.
Some things i want to fix that are bothering me a bit, but not a major issue:
1. The coolant hard lines running to the turbos are sitting a bit higher than they should, and i see that its because when they rebuilt the motor, it looks like they werent routed perfectly, so instead of slipping under one of the lower pipes, its resting on top, and keeps the pipes lifted. so ill tackle that when i replace the Auxillary Coolant pump under the Charge Cooler.
2. Change the 4 rubber Coolant Pipes and Heat blankets by the turbos as preventative maintenance, pretty cheap from BMW.
3. Maybe new Charge pipes, as the locating clips for the Coolant hard lines are broken, but its not a major issue, ill assess once i eventually fix the routing issue on the coolant lines.
Also since the Software update from BMW a few weeks back, i lost all my coding i did to the car.
So i redid a few things:
Turn Signals on HUD
Entertainment info on HUD
Navigation on HUD
Lane Assistance on HUD
Comfort Closing Delay disabled
Easy Entry on seats activated (Moves the seat back when you switch the car off so you can get out and in easier, and puts the seat back to the Memory position when you Close the Door and put IGN on again. )
Easy Entry for Steering Wheel activated (Moves the Steering wheel inward, and then upward to help make space for exiting and entering the car)
There are a few more tings id like to play with, but for now thats all i need really, the Easy Entry has been the nicest addition, now i dont have to rub the side bolsters when getting in and out.
Also, i sorted the Seatbelt issue where it doesnt retract, i pulled them out completely, quick rub down with a microfibre, then sprayed Silicone Spray very liberally on the belt, and inside the mechanism as i was feeding it back.
Both Driver and Passenger belts now retracted and feel like new.
Shot everyone, so far, im enjoying the hell out of the M6.
Glad the down pipes will help you out bud
