P1101 OBD2 Fault Code on 2007 Mercedes ML320 CDI: Causes and Solutions

Model: ML320 Fault Code: P1101 Posted: 2019-10-22 21:09

Hello everyone, I'm experiencing a serious issue with my 2007 Mercedes ML320 CDI. The vehicle enters limp mode and then shuts down unexpectedly after the engine stalls. When attempting to restart, it turns for a few seconds, runs for about two seconds, and then stops again. My OBD2 scanner shows fault codes P1101 and P0299. I've searched online but found limited information specifically for the ML320 CDI model — most resources discuss these codes in relation to other vehicle makes, not this Mercedes variant. I have an Alldatadiy subscription, but the codes aren or showing up in the official Star documentation for my model. This discrepancy is confusing and I'm seeking clarity on what P1101 means in the context of the 2007 ML320 CDI, as well as potential causes and fixes. Any insights, troubleshooting steps, or known solutions from owners with similar issues would be greatly appreciated.
