Mercedes W204 OM646.811 hesitation on acceleration at high revs
Hi friends,
Hi have a Star Mercedes C220CDI 2008 with engine OM646.811 and a few days ago, when i accelerate hard, around 3500rpm, i feel a slight hesitation for about 1s, like a deadspot, and then it goes normal but it repeats constantly at high revs!! No error light in dashboard neither no CDI errors at Mercedes Xentry !! The values of fuel and the Y94 valve are Red, i don't know if the problem is there!! I think that the Injection Volume is lower too! I feel a little rpm fluctuation too at idle!
Does anyone have an idea of what might be?!
