Can't search on Bad Injectors here

[Ron97M3]

Search engine says the Word BAD is not allowed in a search, go ahead try it.
Come on the word BAD isn't so BAD is it?

I was interested in how long injectors go in M3s before they give troubles.
I guess it could be bad injector rubber rings so leaking or truly dirty or failed injectors right? Any ideas how long these last?

The disc-type injectors last a damn long time - in the hundreds of thousands of miles range. You can send yours off to get cleaned and tested. BMW specs injectors with a very small acceptable window, so you are not likely to need custom flow-matched sets of injectors.
