2.0 DCI: Error memory and messages e.g.

Strange problem Partially check the message on the injection system / Limiter Check/ Tempomat Check The following errors are stored in the error memory. They can also be deleted. Then they are off until the lamp goes on again. The message also goes away in between times again No limit to 120km/h when the error is there. No more consumption according to BC. However, I notice generally, that if one steps out of the idle briefly on the gas, it is such a shock. The engine bearings are only recently new so that doesn’t come from it. Since apparently everything seems ok in the live values.. Have someone ever had a mistake? Where should I look? The only thing I notice is that the last regeneration is supposed to be 154tkm, the vehicle now has 155600 on the clock. Fuel pressure in the stand gas about 270-280 bar goes up to 550bar at load. Charge pressure about 1.0 bar in the stand up to 1.2 bar at the gas giving in idle. t Diagnosis measurement also seems ok. Glow plugs also seem to work and can be controlled on the PC. Does the cart randomly measure an oil thinning and then throws this error? Can one then also read this out? Am in April according to the display and regularly run again with the change.
