Nice. I recommend you do aluminum/silver ZHP cube trim for the interior and get clear corners/indicators/tails for a nice clean look
Thanks, I will leave interior as stock as I like how it looks, also the orange indicators, the things I plan to do aesthetically is new light smoked tail lights (my left side looks terrible) and medium or dark window tint on the sides/rear. :thumbup:

I'd check to make sure your CCV isn't leaking any oil before you replace the pan gasket. I'd also check to make sure you vanos oil line isn't leaking either.

I probably wouldn't have replaced the sensors if they weren't throwing a code... but that's just me.

Looks like you've got a really nice car. Happy to see other doing all this type of work!

Replaced expansion tank along with its lower hose that was leaking, water pump, thermostat and 50/50 BMW coolant-distilled water; plus main hoses received new o-rings.
Old thermostat was almost leaking.. a fine sandpaper didn't cleared imperfections on the block completely so used some RTV to make sure.
The expansion tank had the famous crack on the side, it wasn't leaking at all but good it was replaced as PM.
Also found the coolant level sensor broken inside the old tank... car was turning "add coolant" light on/off intermittently, replaced with a new sensor and its solved :)

Here is some updates;
-Proper oil change, was surprised to see that Mobil1 is not approved by BMW anymore
-Fixed driver seat that was not moving forward/backwards (broken plastic pin)
-Fixed left fog light and temperature sensor wiring (plastic cover was broken /wiring damaged)

Parts here to do next:
-Shifter repair kit, its very loose sideways
-Transmission shifter and rear seals + guibo

This will be fun due actual exhaust status... I might need to replace this whole thing anyway..
