The following situation – CR-diesel – vehicle is always warm off – cold start a bit tough, does not start immediately, the longer service life, the more clearly – at 5 days service life 10sec-organs – with multiple annealing and thus longer runtime of the fuel pump better start – smell immediately after cold start – 1-2 minutes after cold start clearly white smoke, also smell – calms down a few minutes and later again – cooling water level in order – oil consumption not significant – injectors before 7000km with the Bosch-Serive controlled and allegedly fine. – slightly increased consumption (0.2-0.3l) – subjectively slight performance loss (but can also be mistaken) I have a clear assumption. I think this is also obvious. I would be interested in what you think. Whether something else can be considered.
