hey to everyone,
just got an 05 with 316000km and was wondering how to indicate worn injectors beside excessive smoke,
could one indicator be when it takes a few seconds until it fires up, due pressure loss through the injectors into the burning chamber?then of course it takes some time for the high pressure pump to build it back up.
as i said its just a thought.

maybe you guys have other ways to tell worn injectors beside excessive smoke without pulling them.

thx Thomas

A hard\slow\no start can definitely be worn injectors. Best way to get an idea on the health of the injectors is a return flow test and cylinder contribution test.
