N52 328 base. As in no MMI/I drive bullshit.
Common problems I see.
Waterpumps
Valve cover leaks
Eccentric shaft sensors
Belt tensioners on the no roller cars, later ones have secondary rollers. The big deal there is tossing the belt and stuffing it into the timing cover. You aint lived until you go into one to get a damn drive belt out of the oil pan.
Starters are simply put, shit.
Same radius arm bushing issues BMW has had for years
Rubber peels off the plastic bits
Exterior hard rubber trim falls apart
Coils, mostly on the n52K with the plastic valve cover.
Bolts breaking off on the magnesium valve cover ones. (early engine)
Oil stand profile gaskets leak oil
Fuel pump outlet nipples crack
Same map cooling faults as before but, a hell of a lot harder to replace the stat.
Window switches
Very expensive (compared to a 5hp) trans service. Mostly due to the cost of the filter/pan.
Now, on the subject of the modules. Yes, in BMW world if you replace a module you have to code it, if you are using ISTA all the modules have to be coded to get the I levels the same point. Autologic allows you to replace a single module and CIP to the level of the rest of the car. Easy stuff. The e90/1 cars are simple. You dont get into really insane stuff until the e65/6 cars and into the F cars.
Overall, just find a competent shop with autologic and let them deal with it. I find them to be about on the same level cost wise as the e38 was adjusted for inflation. At least the damn clusters live now.
Be mindful of proper oil service with the proper oil. 7500 or 6 months works well and IF you are looking at a N55 powered car, make sure the vanos gear campaign has been done.
If you are a tuner, avoid the n52. a grand for a whole 30hp aint worth it. For a tuner, the 335 is the one you want, 4500 will get you over 400 and they are staying together to 450, after that, time for head work, studs and a good, rod piston set up.
