PixelTonic Posted October 10 Share Posted October 10 The vehicle has just undergone servicing. 2011 F11 520d model. Following two brief journeys (about 5-10 km each), the engine oil high error appeared on the IDrive. The dipstick indicates a level slightly over the maximum, as seen in the image. I enquired with the mechanic, and he indicated that the amount would be acceptable. Do you propose draining some fluid or just operating it to allow for potential settling? Should the oil dipstick be examined immediately after driving or after the engine is completely cold? I have also seen information suggesting that it may relate to the incomplete cycle of the DPF regeneration. I possess substantial automotive expertise; nevertheless, this is my first experience with a diesel vehicle, so I appreciate any guidance. Link to comment Share on other sites More sharing options...
BrambleBurt Posted October 10 Share Posted October 10 The level on the dipstick is OK; disregard the notification and replace the level sensor during the next oil change. My previous 330d often displayed the warning, even though the oil level was enough; I replaced the sensor during the servicing. Link to comment Share on other sites More sharing options...
DaisyDrift Posted October 10 Share Posted October 10 Place confidence in the stick The stick is divine. I am old-fashioned and lack faith in such technologies. Link to comment Share on other sites More sharing options...
PixelTonic Posted October 10 Author Share Posted October 10 I concur, but felt it necessary to enquire. Link to comment Share on other sites More sharing options...
PixelTonic Posted October 10 Author Share Posted October 10 I would trust the stick; but, I was concerned about the portion exceeding the maximum level. Uncertain on the sensitivity of the N47 engines. 😂 Link to comment Share on other sites More sharing options...
BrambleBurt Posted October 10 Share Posted October 10 That does not seem to exceed the maximum level; it only resembles an oil residue. If it were over the maximum, the maximum indicator would also be coated in oil. Link to comment Share on other sites More sharing options...
Automan Posted October 10 Share Posted October 10 A commendable series of YouTube movies by a somewhat eccentric Russian individual demonstrates the precise volume (in litres) of oil required for an engine before the crankshaft aerates the lubricant; he used transparent Perspex sumps for clarity. It is a substantial quantity! Should I locate the videos, I will upload them thereafter. Link to comment Share on other sites More sharing options...
BeardAndBeans Posted October 10 Share Posted October 10 Precisely accurate, I would assert. Thoroughly clean the stick, and the portion over the maximum mark will be revealed as just residual oil that was not removed prior to inspection. Link to comment Share on other sites More sharing options...
