My 2023 Ducato 8, 2.2L, 160 hp, has a problem: The intercooler ices up on the first cold start as soon as the temperature drops below 2°C. Then it rattles loudly as soon as it tries to draw in air again. It sounds similar to a compressor running dry and is dependent on the engine speed. When it gets warmer or the intercooler thaws, condensation forms. This is noticeable by the thick steam coming from the exhaust. Once everything is warm, the noise stops. However, if the intercooler cools down so much, for example in traffic jams or after driving downhill, that the air inside condenses and water gets into the combustion chamber, the engine stutters and goes into limp mode for a few seconds.
There's an oil-water emulsion (mayonnaise-like) on the oil filler cap. This indicates that the oil is being diluted.
I drive long distances more than 90% of the miles, and the last oil change was 2500 miles ago.
In AlfaOBD, I see that the DPF has regenerated every 143 miles since car is born. This would explain why too much diesel is getting into the oil. This would likely be the case with a driving profile like that of a mail carrier, but not on long-distance journeys.
Apps like Carscanner and OBDLink constantly display an engine oil temperature of 215 °C. This is either an interpretation error of the OBD2 standard protocol or the sensor is defective. The on-board computer displays the oil temperature correctly with 0-2/4 bars. In AlfaOBD i can't find the oil temperature parameter.
AlfaOBD displays the following:
-Variable geometry turbocharger valve status: Not calibrated
-Crankcase ventilation preparation: Not calibrated
-Air conditioning calibrated: No
-Brake control unit calibrated: No
I've been to the garage three times so far. Each time they said they couldn't find any fault. I've also tried to find the cause myself, and that's all I know. In 3 weeks i've a apointment again
