Good day everyone
I'm seeking help with my 2019 Mercedes W167 (GLC, assuming it's a hybrid model) that's showing a PTCU fault with the specific code P0CD700. The fault message indicates 'Coolant Temperature Sensor 2 in Hybrid Voltage Battery has a short circuit to ground'. I'm looking for guidance from anyone with experience in Mercedes hybrid systems or this specific issue.
- Can anyone explain what this fault code means and its impact on the vehicle's operation and please where the exact sensor location.
- What are the likely causes of this short circuit — is it the sensor itself, wiring, or something else?
- Have you encountered this issue and found a solution? What steps did you take to diagnose and fix it (eg, sensor replacement, wiring repair, or other troubleshooting)?
- Do I need to visit a Mercedes specialist, or can this be addressed with general diagnostic tools/expertise?
I appreciate any insights, personal experiences, or recommendations for diagnostic approaches. If specific tools or part replacements are needed, please let me know. Thank you in advance for your support and guidance!"
