The best way to check the problem is to grab your 17 mm open end wrench and
crack #1 injector line, if the sound goes away-that's your problem. If not,
tighten the injector line and wait for the engine idle to smooth out, then
repeat on #2, #3, etc. until you find the source. If none of them quiet the
sound, the problem is deep in the engine.

My S350 was nailing horribly when I first got it. The injector springs
were worn causing them to fire too soon. A set of rebuilt injectors
quieted things down nicely.
