High Mileage N55
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.
