F23 DIY after watching F22 DIY
So I’ve a 2016 M235i F23 auto that I purchased used ~37k miles. After studying tons and plenty of threads and stickies right here relating to preventative upkeep and watching alot of youtube DIY I made a decision to do the entire mods myself.
99% of movies that I watched have been of people that had the F22 and because the engines are the identical I figured the F23 could be a easy monkey see monkey do.
Issues I ordered:
FMIC, consumption, and cost pipe from CTS turbo (zero fitment points; I used to be in disbelief how straightforward it was after watching/studying horror tales on fitment of some bolt ons)
ATF equipment, oem plugs, cabin filter, Akebono brake pads and coolant reservoir line from FCP Euro
metal brake strains
supplier for coolant, rear diff oil and brake fluid.
It took month to get all the pieces collectively and do analysis to verify I had a good suggestion the right way to method all the pieces.
I began on the high with the plugs, consumption, brakes, brake line and flush, and eradicating cost pipe. After I took out the spark plugs there was some rust left so I simply used a store vac. Brake flush used about 3 bottles of fluid. No downside, going clean. Then I get the automobile on jacks and take off the underside cowl.
1st distinction between F23 and F22. There are two steel bars which might be on reverse sides in the course of the automobile and meet at a degree close to the entrance center of the automobile proper below the intercooler. There are additionally related bars that meet on the center within the rear proper beneath the rear differential.
I used to be capable of get the nut within the entrance off with a Torx key (largest one I had that didnt snugly match, possibly a T60 would match however didnt have one then) so I may work on the cost pipe, FMIC, and coolant however could not tighten again confidently as I used to be afraid of stripping the nut. Altering the rear diff fluid was a ache as I didn’t need to take out the nut holding the bars once more so simply needed to work totally different angles making an attempt to get the rear diff nut off. The FCP Euro vid reveals the man taking the nut off in 10 secs; took me 10 min making an attempt to wiggle round and never have the automobile fall on me earlier than I may take it off.
The ATF equipment from FCP Euro labored completely and moreover the god terrible rear diff and AT fluid odor and the inevitable spilling from filling them issues went easily. Used 6.5 bottles of ZF trans fluid and two full bottles of rear diff fluid (costly stuff so do not spill). Did I point out they stink? Stinks worse once you warmth up the ATF and let it spill out everywhere.
The one different factor that was totally different on the F23 was that I didn’t discover the aux radiator within the driver aspect entrance bumper. There’s nothing there. I deliberate on utilizing the aux radiator to empty the coolant for a drain and fill however was shocked to seek out nothing. I drained ~1.5 gallons of the coolant from the coolant hose. I did not trouble to open the passenger aspect to see if the oil cooler was there because the mission took alot longer then I believed and I used to be stinking of diff and trans oil. God I can nonetheless odor it and I did all this about two month in the past.
Anways a giant thanks for all the nice information and recommendation from discussion board members as I felt very ready to deal with this mission and have had no CEL or any points the final two months. The automobile feels smoother total and the extra audible turbo spoiling noise undoubtedly make all of the work really feel worthwhile. My subsequent mission is getting new wheels/tires however this rabbit gap appears very darkish and twisted.
Going ahead I do know that I would like to observe for the OFHG, valve cowl gasket, tensioner belt, and the water pump and thermostat. If there’s the rest I ought to be aware of please let me know.
