X Klasse oil temperature sensor issue

I see you are experiencing a similar issue to one I encountered with my own Mercedes X Klasse, although I must say my engine is petrol, not diesel. The symptoms you describe, specifically the oil temperature warning light and the intermittent oil pressure lamp illumination, do indeed suggest a potential fault within the oil temperature sensing system. Have you by any chance inspected the wiring harness and connector associated with the temperature sensor for any signs of physical damage, corrosion, or loose connections? It is often the case that environmental factors can degrade these components over time, leading to erratic sensor readings.

Cheers for the reply I checked the plug, seemed ok visually Any chance you recall the specific error code you pulled Trying to narrow down if it's the sensor itself or definitely wiring

I understand your concern regarding the precise nature of the fault. Unfortunately, I do not have access to the specific diagnostic trouble code that was registered during my incident. However, I must strongly advise that, given the potential implications of an inaccurate oil temperature reading on engine lubrication and overall performance, it would be prudent to seek professional assistance from a qualified automotive technician. Continuing to operate the vehicle with a suspected sensor malfunction could potentially lead to more extensive and costly repairs in the long run. A workshop will be able to check the car sensor and diagnose the specific issue.

Appreciate the advice Turned out it was as suspected - faulty oil temperature sensor cable New cable and sensor installed, cleared the code, and all good Total damage 95€
