I am about to purchase a 2018 340i M sport with a M/T, 35k miles. Is there anything I should do right away preventative maintenance wise? Not looking to do any mods to it, just want something that will be solid for years to come. Thanks for any input
Check for evidence of modifications, then probably save up for a few of the bigger maintenance jobs down the line.
Say near 100k miles I would be preparing for: water-pump, ignition parts replacement interval, oil leaks, DI carbon build up cleaning/walnut blasting, and possibly cooling system maintenance
You might run into other unexpected issues along the way, but the aforementioned would be bigger maintenance jobs I’d expect on the car after some miles
Other than that, do fluids maintenances diligently and enjoy a damn good engine especially backed behind the 6MT
I like the idea of replacing my G37s with something like a 340i
