Hey guys - I picked up a 2012 E92 335i xDrive last fall. It has 152k miles on it - Water pump replaced, HPFP replaced, and Valve cover gasket replaced. Putting new plugs + coils in it soon. I think all the previous owners had purely highway miles on it - i think im the first owner to drive it hard She runs fantastic now with MHD Stage 1 tune but I plan on going FBO soon and wanted to know what I should be wary of. Havent seen too many N55 models with this high mileage

Auto transmission.

Thanks

How's the transmission feel? If it hasn't been serviced, it's probably too late for that now. Plugs and coils are never a bad idea if you're planning to run more boost, and of course an oil change should be at the top of the list too. I believe gasket failures and the subsequent leaks are the most common issues with the N55.

Transmission shifts fine and feels good.
I know the valve cover gasket has been replaced but ill check for other gasket failures and leaks

Thank you

I had the trans fluid changed for the first time on my n54 at 157k with no ill effects. Burst a trans cooler line at 166k and lost every drop of fluid and replaced it again. Still shifted great. Ymmv but I think it will be fine.
