Problem with oil light on a 2018 Mercedes GLE Diesel

Hey guys, I have a problem with my 2018 Mercedes GLE Class Diesel. The oil light is on and the warning light is flashing in the speedometer. Could it be the engine oil pressure control? Has anyone had similar experiences and can give me troubleshooting tips? Would like to know how this was fixed in the workshop and what experiences you have had with it. Thanks in advance!

I get a generic error code with no further info from carly. Chatgpt says the following: Generic fault code P052E71 generally indicates a problem with the crankcase breather valve. The exact meaning may vary depending on the vehicle manufacturer... Is this answer correct? What is the remedy?

The P052E code typically relates to a problem with the Positive Crankcase Ventilation (PCV) system, specifically the crankcase breather valve. This can lead to issues like increased emissions or engine performance problems. Start by checking the PCV valve and its connections for any signs of damage or blockage. If you're unsure or need further assistance, it's advisable to consult a professional mechanic. Let us know how it goes or if you have more questions!
