25% increase in fuel consumption after injection nozzle replacement I have G400 Cdi 2004 model where all injector nozzles where replaced with factory new ones. Part number of new injectors is A 628 070 04 87.
Injectors where replaced by a Mercedes workshop.
When driving with new injectors I have measured a 25% increase in fuel consumption.
Is it required to do some kinf of tuning after replacing injectors?
