Misfire on engine?

English:
Misfireproblem at the engine when it's cold (2 cars - BMW 335i from '06 and '07).
After a few kilometres there is no problem (after turning the engine off and on) and the cars goes very well.

Yesterday reduced fuelpressure has been noticed in the carcomputer on one of the cars and the workshop now will check this up. New sparkplugs and coils did not solve the problem - only one day. If you know the reason concerning this error please let us know

Injectors? -> http://www.e90post.com/forums/showthread.php?t=466031

Danish:
Her i området har 2 stk BMW 335i fra hhv. 2006 og 2007 pludseligt fået samme fejl:
Når motoren er kold, tænder den ikke på alle cylindre. Der skal ikke megen temperaturstigning til (et par km's kørsel), før alle cylindre kommer med - man slukker og tænder lige for motoren en gang. Efterfølgende kører bilerne perfekte.

Der er ikke megen hjælp at hente i fejlbufferen på bilerne, og nye tændrør og -spoler på den ene motor har ikke hjulpet. Fejlbufferen på den en bil viser, at benzintrykket er lidt lavt, men denne oplysning er ikke checket endnu.

Hva mon der kan være problemet?

At the same time 3 cars (all '07 BMW 335) in the workshop had the problem and on 2 of them 1 Injector failed. On the third car the fuelpump caused the trouble.
