Identifying the oil vapours leading to the accumulation beneath the rocker cover is an excellent initial step. Have you attempted to thoroughly clean the area to identify the precise location where the new oil starts to leak? Identifying the origin could assist an individual in determining the reason for you.

Greetings, My offspring is coming to visit. He operates a 2019 Countryman. He observed oil fumes emanating from the engine compartment in recent months. We inspected the engine compartment and I detached the cowling, observing oil accumulation in the channels directly beneath the rocker cover on the front (radiator) side of the engine. The oil loss is minimal. Do you have any hypotheses regarding the likely origin? I am aware that these engines contain numerous plastic components that may be susceptible to malfunction.

Apologies for the oversight.

The inquiry was directed toward the original poster.

Indeed, consistently at intervals. Even when Mi-Drive is deactivated, the electric motor replenishes the 48-volt battery, in addition to regenerative braking. I am of the opinion that the 48-volt battery is replenished during coasting without fuel and, naturally, while braking. I seldom examine that power flow diagram. It is somewhat of a ploy.

OP, are you indicating that there are no flow arrows to or from the mild hybrid battery in relation to the engine or drive wheels on the Energy Monitor display? At any moment.

You might be conflating the turbo boost with the Mi-Drive 48-volt battery enhancement. There exist two markedly dissimilar techniques to enhance engine horsepower. The turbo operates independently while the Mi-Drive is engaged by the operator. It is imperative that you consult the vehicle's manual.

Silly inquiry, but how does one engage M mode?

That is not the operational mechanism of my 2026 MHEV.

I am not required to set it to M mode. It appears to activate automatically when I increase speed.

It is possible that the 48-volt battery has ceased to function. Neither a depleted battery nor a malfunctioning cell should occur. Do you consistently operate it in M mode?

I possess the Turbo S Premium Plus, and the M-Hybrid boost fails to activate during acceleration. I have observed that the engine exhibits a delay and lacks the vigour it once possessed. I contacted the dealership and was informed that they are currently 3-4 business days behind in their service department, necessitating that I drop off my vehicle due to the excessive number of components requiring diagnosis within a single day.

Perhaps…It strikes me as peculiar that I should be alerted if the oil level is insufficient, even while the engine is operational. Nonetheless, I receive no notification.

🙃🙃🙃

Maybe the sensor?

I appreciate the recommendation. I adhered to the protocol to the best of my comprehension. The vehicle was stationed on a flat surface and had been turned off for multiple hours prior to my inspection of the level. I re-examined it after approximately one hour.

Did you neglect to adhere to the Owners Manual regarding the oil level inspection procedure? You ought to attempt that initially.

Greetings to all,I possess a 2017 Volvo V60 D3 2.0 diesel with an automatic gearbox, presently at 189,477 kilometres. The vehicle is equipped with an electronic oil level sensor and lacks a manual dipstick.I observed an anomaly in the oil level measurement.At 188,072 kilometres, I replenished the oil to nearly the maximum level. At 188,490 km, following a distance of 418 km, the oil level remained nearly unchanged.At a distance of 189,477 km, the indicator reads LOW.What appears peculiar to me is the absence of a gradual decline in the exhibited level. It remained at a consistent level before abruptly indicating LOW.Yesterday, after the vehicle had remained stationary on flat terrain for multiple hours, I examined the oil level and it indicated LOW. The dashboard did not display an independent warning notification.I examined it once more today after the vehicle had been stationary for approximately one hour. Remarkably, the screen exhibited MAX / OK for approximately 5 seconds before abruptly transitioning to LOW.The vehicle operates typically, and I have not encountered any oil pressure alerts.Might this be a defective oil level sensor or a problem with the electronic oil level gauge? Has anyone encountered the oil level indicator fluctuating from MAX/OK to LOW in this manner?I have refrained from adding additional oil as I wish to avoid overfilling in case the sensor provides an erroneous reading. Any guidance or comparable experiences would be highly valued! I appreciate it!

Haha, I just realised the ix1; my apologies. I possess no knowledge regarding electric vehicles; I break out in a rash when I approach one, haha.
