Mercedes ML320 (2008) P1101 Fault Code: Diagnosis and Resolution Guide
I recently received a P1101 fault code on my 2008 Mercedes ML320 CDI diesel model, but I'm struggling to find reliable information about this specific issue. Most online forums are either asking for help or lack detailed solutions — I can't seem to find any posts that clearly explain what the actual cause of P1101 is on this vehicle. Can anyone share their experience or technical diagnosis related to this code on a 2008 ML320 CDI?
The P1101 code on Mercedes diesel engines like the ML320 (2008 model) typically refers to an issue with the intake air temperature sensor. However, it's important to confirm that your diagnostic tool provides accurate readings specific to Mercedes-Benz diesel systems — generic OBD-II readers may not detect or interpret this code correctly. Please share more details about your scanner and any associated symptoms (e.g., engine performance, warning lights) so we can better understand the root cause.
