IrvesBMW Posted November 21, 2023 Share Posted November 21, 2023 Greetings, I would like to bring to your attention that an unexpected message has shown on the iDrive system of my BMW E70 4.0d xDrive LCI model. The engine oil level is too elevated, resulting in a decrease in the power output of my vehicle. Do any of you have insights on the causes of this occurrence and any solutions to address it? I express my gratitude for your assistance. Quote Link to comment Share on other sites More sharing options...
keithmerc220 Posted November 21, 2023 Share Posted November 21, 2023 Is there a dipstick included in the 40d model similar to the one found in the 35d model? In order to access the desired component, it is necessary to detach the intake snout. Quote Link to comment Share on other sites More sharing options...
IrvesBMW Posted November 21, 2023 Author Share Posted November 21, 2023 Yes, I have obtained an item that has reached its maximum level. At one point, it had slightly beyond the average level. I did not add anything. One intriguing aspect is to the factors that contribute to the elevation of the level. I express my gratitude for your assistance.

SkippyTom Posted November 21, 2023 Share Posted November 21, 2023 The observed phenomenon of level growth may be attributed to several factors, with coolant or fuel being potential explanations. It is advisable to assess the coolant level and inspect for the presence of oil emulsion in both the coolant container and oil fill cap.

keithmerc220 Posted November 21, 2023 Share Posted November 21, 2023 While it is important to note that this scenario may not be applicable to your specific situation, there have been instances when diesel fuel has infiltrated the engine oil due to either a malfunctioning injector or fuel pump leakage. I would recommend inspecting the oil for indications of an excessive presence of diesel fuel. Quote Link to comment Share on other sites More sharing options...
IrvesBMW Posted November 21, 2023 Author Share Posted November 21, 2023 I have verified that the coolant level is within acceptable parameters. There is no evidence of oil contamination seen on the coolant bottle and oil cap. Quote Link to comment Share on other sites More sharing options...
IrvesBMW Posted November 21, 2023 Author Share Posted November 21, 2023 I conducted a verification process using the application Insta+. There is no issue related to the injector. There are no reported issues with the gasoline pump. Quote Link to comment Share on other sites More sharing options...
SkippyTom Posted November 21, 2023 Share Posted November 21, 2023 Upon doing a brief examination, it seems that the gearbox cooler is not integrated with the radiator. If the oil level has increased, it is indicative of a potential oil leakage. One such method for oil analysis is using laboratory techniques to assess its quality.

keithmerc220 Posted November 21, 2023 Share Posted November 21, 2023 It is possible that no problem codes will be generated for these particular concerns. In summary, there seems to be a foreign substance contaminating the oil, and based on the absence of a milky appearance, it is likely to be diesel fuel.

SkippyTom Posted November 21, 2023 Share Posted November 21, 2023 In my perspective, the presence of diesel fuel in the oil has detrimental effects on the engine's bearings. Quote Link to comment Share on other sites More sharing options...
IrvesBMW Posted November 21, 2023 Author Share Posted November 21, 2023 However, it is important to understand the process by which diesel fuel might get mixed with engine oil. I used the INPA+ software to assess the condition of my injectors, and I can confirm that they are functioning optimally. I express my gratitude for your assistance.

SkippyTom Posted November 21, 2023 Share Posted November 21, 2023 I am uncertain about the matter, but it is possible that an engine may need oil. However, it is important to note that an engine does not possess the capability to produce oil or replenish its own oil levels. What is the process by which an automobile starts its engine operation after a period of inactivity, such as overnight rest? Does the vehicle exhibit a seamless performance, or does it encounter challenges, perhaps resulting in the emission of smoke from the exhaust system? One possible course of action involves extracting the oil and visually inspecting its appearance. Subsequently, transferring the oil to a transparent container, such as a jerrycan, and allowing it to settle for a period of one to two days. If substances other than oil are present in the container, they will be observable. Quote Link to comment Share on other sites More sharing options...
IrvesBMW Posted November 21, 2023 Author Share Posted November 21, 2023 The absence of evidence in INPA+ (or maybe ISTA+) does not necessarily imply the absence of either of the two occurrences. Quote Link to comment Share on other sites More sharing options...
IrvesBMW Posted November 21, 2023 Author Share Posted November 21, 2023 After a brief period of time, the vehicle starts operation in an optimal manner, exhibiting a seamless performance devoid of any peculiar speculations. However, it experiences a decrease in power output beyond the speed threshold of 40 miles per hour. There is an absence of smoke emissions in the exhaust. Upon using the BimmerLink APK on my smartphone, I saw that the Diesel Particulate Filter (DPF) exhibits a soot level of 87%. However, it indicates that the regeneration process was completed 235 km prior and does not need further regeneration. This occurrence is peculiar. Today, I will be engaging in the task of changing the engine oil in order to observe the potential outcomes that may arise. I express my gratitude for your assistance.

IrvesBMW Posted November 21, 2023 Author Share Posted November 21, 2023 Indeed, I am referring to the use of ISTA+ software at a nearby BMW dealership. Quote Link to comment Share on other sites More sharing options...
keithmerc220 Posted November 21, 2023 Share Posted November 21, 2023 Store the oil in a transparent canister that allows for lateral observation. Quote Link to comment Share on other sites More sharing options...
