A Klasse hybrid transmission issues

I am familiar with the challenges you describe I experienced similar transmission problems in my Mercedes C Klasse The symptoms you list – the delayed response from the paddle shifters, the rough shifting, and the emergency mode activation – strongly suggest a faulty transmission control module From my past experience, I suggest examining the wiring harness and connectors associated with the control module Corrosion or damage to these components can sometimes mimic the symptoms of a defective module Did you check the diagnostic trouble codes yourself or did a workshop do that

Thank you for the insight I performed the diagnostic assessment myself using a professional-grade scan tool The error code unequivocally points to the transmission control module I had not, however, considered the integrity of the wiring harness and associated connectors Could you elaborate on the specific areas of the harness and connectors that warrant particular attention during inspection

Certainly When I inspected mine, I focused on the connectors closest to the transmission control module itself, paying close attention to any signs of corrosion or loose pins Furthermore, I traced the harness back a short distance, looking for any points where it may have rubbed against the chassis or other components, potentially causing damage to the insulation Given the symptoms and the error code, it is probable that the control module itself is the root cause I would recommend taking your Mercedes to a trusted workshop for a comprehensive evaluation and potential replacement of the affected transmission control unit

I appreciate your guidance and shared experiences Following your advice, I meticulously inspected the wiring harness and connectors, but found no apparent anomalies Consequently, I proceeded to engage a reputable workshop, wherein they confirmed the diagnosis of a defective transmission control module The unit has been replaced, and the transmission is now functioning flawlessly Thank you again for your assistance with these transmission problems
