Mercedes ML Diesel Water Sensor Problem

Water sensor issue on an ML? I had something similar. Check engine light, rough running, and auto electronics acting up. Did you check the connections well? Plugs get corroded or loose sometimes.

When you had this, could you find the exact electrical fault location or root cause through sensor testing? Did you also get a water sensor error code?

I didn't do much sensor testing, it was beyond me. The error code was similar. I took it to a workshop and they fixed the electrical fault. A proper diagnosis is probably best.

Thanks for sharing. I'll get a technician to diagnose the auto electronics issue and test the sensor thoroughly. Professional help seems best to avoid more problems. Thanks again.

Hello! I had a flashing light on a Mercedes ML, the cable was in the trunk, and water got in there without me realizing it. Later, the problems started: no left turn signal, the wipers didn't work, and the electric seats stopped functioning. Since I discovered the water problem, how can I remove the water? Do you think the computer will work as before? What should I do? Thank you.

First, ensure the vehicle is parked on a level surface and disconnect the battery to prevent any electrical issues. Remove any visible water using towels or a wet/dry vacuum. Allow the area to dry completely, using fans or a dehumidifier if necessary. Inspect the affected electrical components and connections for corrosion or damage. If the computer or any components were submerged, it's crucial to have them inspected by a professional, as water damage can lead to safety issues. Let me know how it goes or if you have further questions!
