Anyone DIY spark plugs yet????

I can't find any videos on this for the F90. There are some for the prior model. Does not look that bad, but have to move a ton of stuff out of the way. Trying to decide to DIY or have dealer do it. 25k service.

I also want to do this myself, but it looks worse than the F10 as far as getting stuff out of the way.

I haven't seen anything but, aren't the spark plugs including during the first 3yrs 36k for original owner? Not sure what the service manual states.

Same motor minus a few revisions as F10. How much is your time worth and what does the dealership charge lol? Certified independent shop maybe.

Yeah it seems like it should be offered in the first 3 years, but I can't find an answer about when they should be changed. It's also fun to turn the wrenches yourself and know it was actually done and done correctly.

If memory services me correct normally at Inspections I & II or every third oil change for M cars they recommend plugs ( 3yrs or 30,000 miles whichever comes first).

I'm going to ask tomorrow as I'm going in for the 1st year (or 8K) oil change.

It's great that you found this. Looks like it's just about as involved as a spark plug change could be, unfortunately.

Yes, but less intimidating than without a guide. Interesting 'engineering' that requires so much disassembly for a routine q25k mile spark plug swap over. The coolant tank thing is just dumb. I guess the dealers have a stock supply of replacement plastic clips and connectors ready for 'routine' service on these cars when they are 5 or 6 years old and have had those clips undone a few times. I just wonder if you can get away with just moving the coolant tank up without removing completely. The rest of the plastic covers and ECU modules are no big deal. At least you don't have to remove the air boxes like you do in the F10.

I was looking at another breakdown sheet, on a different page of the same website, and they showed how to remove the coolant tank on the passenger side also. This breakdown does not mention it? I think it may be in error?

I'll poke around this weekend, I took a quick look a few times, but as usual something else called me attention.

At this point I am toying with keeping this car for 10 years and want to know if I can DIY for the routine stuff. Next thing to consider is the timing belt service. Those routine must be done things are different than the fix a broken part deals which would be covered by an extended warrantee.

This "special tool" is simply priceless. Look at the name of it.

"Original Rubber Hose." This is the Original Rubber hose that was used to beat people back in Germany.

Haha, the "original" rubber hose. I totally agree that for those of us planning on keeping this car long term, we will need to know how to do stuff like this. I'd like to eventually have enough info and tools for transmission, transfer case, diff fluid changes, etc. I'd also like to install an oil catch can, but extra space is basically non-existent under the hood.
