G Klasse Auxiliary Heater Problem

The error message stored within the vehicle's memory is useful for diagnosing the issue To assist in identifying the root cause of the auxiliary heater malfunction could you please provide the specific error code Furthermore has the vehicle's climate control system been exhibiting any other anomalies such as unusual blower motor activity or suspected coolant leak A comprehensive assessment of the ventilation system's operation will aid in determining the most probable origin of the fault

Okay I can check for the specific error code later But regarding other symptoms I haven't noticed anything weird with the blower motor or climate control No obvious coolant leaks either Could it be a simple issue like a fuse or maybe a faulty sensor

Given the absence of other discernible symptoms and the presence of an error code related to the auxiliary heater a defective glow plug is a plausible cause Diagnosis via the error code remains essential If the error code reported implicates the glow plug replacement is indicated Be advised that replacement at an authorized repair facility is advisable Parts and labor costs are estimated at 440€

Thanks a lot for your help I got the error code checked and you were spot on it was the glow plug I took it to a workshop they replaced it and now the auxiliary heater works perfectly again Cost me exactly 440€ Appreciate the guidance
