Service checklist

[Bmwdeven]

So it seems my TA’s are finally on their last leg. That’s just one of many things I need to address for my car. The reality is I’m not in a position to tackle everything in one go. The most logical thing for me to do is park it in the garage and do a full service over the next few months or year as this isn’t my only car. With that being I have an idea of what I have to get done as shown in my image. Can anyone thing of anything else they would add? Or specific manufacturers or service providers they would go through?

mileage?

i'd add:
- fuel injectors
- fuel tank breather valve if it hasn't been done ever, along with fuel pump if car is >100k (filter is integrated, so this is about the filter not the pump)
- standard fluid stuff if appropriate (brake flush, ps flush, coolant flush)

Good call on the injectors and fluid.
I purchased my car at 80k miles and was told Rod bearings and injectors were serviced. Injectors looked new so I didn’t doubt that RB’s we’re done also. Car is currently at 140k miles.

+ spark plugs if they weren't done at ~120K

Bump the fuel breather valve up in priority if you don’t know if it has been replaced. It is a very common point of failure.

Change Diff fluid and DCT fluid (could wait to 100k miles for DCT but I’d do it at >=80k miles). If going with BMW OEM DCT fluid, buy Pentosin DCT fluid instead because it’s identical to the BMW OEM DCT fluid, which is produced by Pentosin, but significantly cheaper. Redline and Motul DCTF are good options too if you go with non-OEM. Check your DCT oil pan for leaks and, if it is leaking, do a full DCT service along with new fluid. I’d recommend replacing the DCT plastic pan with a machined Aluminum pan. I have the larger Slon Aluminum pan with extended oil pickup (it holds 1 L of additional fluid than stock pan).

Thanks for all the input. I think that pretty much sums up the possible maintenance items. On top of all mentioned I’m going to swap out most or all of my bushings/ suspension components that are worn. I’ve never driven this car in tip top shape so I’m stoked to feel the difference with some TLC.

If you’re doing the bushings, there’s a number of spots where you can swap in monoballs instead of rubber bushings for better steering accuracy with no/minimal nvh impact. Cost competitive too. May be worth a gander.

Actually just came across the front control arm bushings from German auto solutions.
Where else can you substitute for monoball bushings?
