Intermediate levers (I.L.) are the rocker arms that changes the amount of lift on the intake valves via the eccentric shaft. Basically a 3rd camshaft to control the intake valves aka valvrtronics. BMW released a SIB for N62 motors for out of tolerance rockers (IL) to be the cause of random misfires on cold starts.

Should not affect once warmed up. So the symptoms also aren't there on warmer climates so maybe that is why there was no recall just on "customer complaint basis"
