Either this is the luckiest E46 330i, or I was stupid and missed a few things checking out the car before I bought it.
Last week thought something was up with the running temperature of the car, also noticed it doesnt heat the cabin with climate control, and some gunk on the exhaust when doing the butterfly golf tee mod.
So bought OBDFusion and logged a trip. Engine was running at max 75 degrees, mostly 71-72 degrees celsius.
Booked the car in to replace the following:
- Thermostat
- Expanstion Tank
- Expansion Tank cap
- Waterpump (not needed, only really before 160k but whatevs)
Turns out, this car was still running its original Expansion tank from 2001 ! :skit:
Colin from Garage808 couldn't figure out why the previous Thermostat caused the car to run cold, because it seems 100% fine, except it wasn't fine for some reason. Either way I asked to replace it regardless of whether it looked functioning after taking it out or not.
Anyways, car feel much better now that its not running rich anymore. Pretty much only things that left for cooling system overhaul is the radiator. The hoses all feel fairly new still.
Since previous post, also did the following:
- Found the reason for cruise control not working. Previous owner replaced input cylinder with OEM one that doesn't take clutch switch
- Re-attached the moonshade properly so I can move it freely when sunroof is open or closed, the proper way. Looks like sunroof was fixed in the past, but moonshade not put back the correct way.
- Gave the car a nice wash and polish, still need to think what is best for the leather inside.
- Recoded some options on the light switch module
- Butterfly tee mod
