critique my maintenance schedule

tranquility · 05-18-2015, 09:12 AM

Just reviewing my maintenance routine. Is there anything glaring that I've missed or that you disagree w/? TIA.

-engine oil (16,000kms/10,000 miles)
-air filter (every 2nd engine oil change)
-brake fluid (2 years)
-brakes (rotors/pads/sensors) (as required)
-shock absorbers (as required)
-sparkplugs (120,000kms/74,000 miles)
-transmission fluid (160,000kms/99,000 miles)
-differential fluid (140,000kms/87,000 miles)
-cabin microfilter (2 years)
-radiator fluid (4 years/96,000kms/60,000 miles)

EDIT: 2011 Z4 35i DCT N54 engine

I'd do brake fluid and cabin microfilter annually

For the gearbox and rear diff gear oil, I'd do used oil analysis to decide if that interval is good enough. I think 30k miles might be better place to start

as for the transmission. I have been warned that the DCT if not done correct can cause serious damage. Please make sure you get this done my the dealer or a indy shop that knows what they are doing.

Yup, I'm planning to do analysis for all oil/diff/tranny soon.

Tx, I'm scheduled to change the tranny fluid soon. Just wondering what the work order should state on the form, e.g. fluid #, # of bottles, replacement plug, etc?

You can contact Mike Miller at mikemillerroundelmag@drivewheels.hush.com and ask him to email you his Lifetime Maintenance Schedule. For people who like to do the optimal maintenance, this is the thing to follow.

Oil should be 5k to 7k if you are running a tune. You will also need to change the spark plugs sooner with a tune as well. Probably around 20k. Everything else seems reasonable.

Thx, I kinda based it off of his schedule (I think you were the one kind enough to mention it to me before?) and from ppl ITF.

I'm just oem, so I guess that I'm good?

Btw, radiator fluid is *2* years, no way it's 4, right?

I did my DCT and diff at around 60k miles at a leading gearbox specialist shop in my country. DCT shifts a lot better after it. I remember reading that DCTs should be serviced even earlier than that. On the website of that specialist they recommended to service DCTs at 40k-60k kms. Thats 25-37k miles.
