Injectors faulty - immediate action recommended
Injectors leaking, Looks like more than one, serious issue with potential of total engine break down, just suffered on it - other indications , oil level increasing. First test indcation used by my friendly dealer - diesel rail pressure loss down to Zero after shut down of engine. This Shows an uncotrolled leak of one of the Injektors. A visual check through the glow plug whole supports the Identifikation which one is the faulty ( at mine it has beeen two) but is not 100%, I decided to exchange them all against reworked injectors.
Background: The diesel rail covers diesel on pressure up to 1600 bar during Operation to support up to 5 load dependent quantified and timely controlled injections. It keeps still pressure despite engine shuts down to support faster Restart.
