DCT fluid service - this ever happen to you?
Featured on BIMMERPOST.com I’ve performed this DCT fluid change 3 times already (every 30K miles) and always replace the fill plug with a brand new one. Between these DCT fluid changes, whenever I perform my oil change every 5K miles, I fill up the DCT as well, keeping the same fill plug. I have the infamous leaky DCT symptom so I make certain it is topped off during the oil changes. I've replaced my pan and the leak still persists.

It’s an aluminum screw not meant to be reused.

BMW is trying “lifetime fill” with the optional M Double Clutch Gearbox on the E90-family M3, and this gearbox requires a special lubricant: BMW DCTF-1 Pentosin. Personally I wouldn’t buy a DCT, but if I had to maintain one I would change its oil at 1,200 miles, 30,000 and every 30,000 miles thereafter. You been avoiding that big hole on The Old Road?

"Lifetime fill" = 100K-120K in my book. 30K seems a little short (and it seems like a shoot from the hip guesstimate than anything based on experience, no disrespect).

good timing, i was just about to order everything needed for a 100k mile DCT service, was going to skip the new fill plug but after seeing this I'm going to get a new one

None taken, but for one who's experienced a failure, it's peace of mind.
