2011 e92 335i, 88k, I bought the car at 86k a few months back. Everything is clean, no oil seepage anywhere. I don't drive much during the week due to close distance work, and roughly 50-100 miles every weekend average. Currently tuned MHD stage 2 and xHP Flashtool stage 3 for trans.
So far I did serpentine belt and pulleys, also spark plugs and coil packs (before tune). No misfire but was sort of rough idle at cold start before spark plugs and coil packs. Next up: Cleaning the vanos solenoids and transmission service DIY.
