Mercedes A Klasse Hybrid Climate Control Problem

The symptoms and error code strongly suggest a faulty interior temperature sensor I'd recommend inspecting the sensor's wiring and connector for corrosion, damage, or loose connections Think of it like checking a lamp's power cord before replacing the bulb Has any recent work been done that might have disturbed the sensor or wiring

Thanks for the quick response No recent work has been done When you say thorough inspection what should I look for with the connector Can I test the temperature reading from the sensor without taking everything apart

It's wise to diagnose before disassembling Look for bent or broken pins on the connector and ensure it's secure While live data from a diagnostic tool could give a temperature reading, the fault code suggests an open or short circuit Consulting a qualified technician for sensor diagnostics might be best The estimated repair cost of 95€ is relatively inexpensive, suggesting a straightforward fix

Okay, I appreciate the advice It seems beyond my skills without risking further damage I booked it in at the workshop and it was a loose connection on the temperature sensor 95€ later, the HVAC works perfectly Thanks
