You can pop test and clean the injectors for much less than new nozzles. Have you atleast tried some diesel ourge? Sure you arent getting air in the line? Are you sure it is idling fast enough?

I would rather just replace the nozzles, they have over 150,000 miles on them, so its time and I would rather put new in and not have to worry about problems for at least another 150,000. I have done a purge, nope no air is getting in, car runs to smooth to be sucking in air, the injector pump is leaking oil from some unknown place. I am not sure if it is idling fast enough. I read this post 240D rough idle - Do I or don't I have rack damper bolt? - ShopForum about the type M pump, seems like the rough idle could be that the pump is out of calibration, and if you can live with the rough idle don't worry about it because to R&R the pump is $$$$

because to R&R the pump is $$$$

$200 on average to put it on a bench.

have the injectors checked. many places are reasonable. Don't replace the injectors.put nozzles in if you need to. I use goff diesel in SLC utah. here is a link to a guy with supposedly good reputation. Iwas thrilled by Goff. My 300 is rock smooth and quiet with pop and balance by goff.
