Mercedes E Klasse Hybrid Auxiliary Heater Problem

Sounds frustrating A defective glow plug could be the issue, especially with a specific error code Have you checked the auxiliary heater system fuses A blown fuse can cause issues Does the error message have more details, or is it a generic auxiliary heater malfunction It could also be a faulty temperature sensor or the blower motor not running normally

Thanks for the reply The fuses are fine The error message is generic Auxiliary heater malfunction no function If it is the glow plug, could I replace it myself with basic tools

A generic error points to the heater itself Replacing a glow plug can be a DIY job, but on a modern hybrid Mercedes, it can be complicated Access can be tricky, and specialized tools might be needed to remove it without damaging the threads Plus, you need to diagnose which glow plug is faulty I recommend a trusted workshop They can pinpoint the problem and fix it correctly You dont want to risk making things worse or damaging other components

Thanks for the advice I took it to my local shop, and it was a defective glow plug The total repair was 440€ At least its fixed now, and I didnt risk messing anything up Appreciate the guidance
