E Klasse exhaust flap problem

Anyone else experiencing exhaust flap issues on their 2023 hybrid E Klasse My model with only 22140 km has started throwing exhaust flap errors The exhaust noise is noticeably louder especially on cold starts sounds almost like a temporary exhaust blockage I suspect the flap motor is kaput Has anyone had similar issues and know what I am looking at in terms of repair

A 2023 hybrid E Klasse owner reported issues with the exhaust flap, experiencing louder exhaust noise, particularly on cold starts, and suspected a faulty flap motor. Another owner with a similar model confirmed experiencing similar symptoms and advised using XENTRY diagnostics to pinpoint the issue. The problem was confirmed to be a defective flap motor, which was resolved at a workshop for 190€.

Did this summary help you solve your problem?

I have a similar E Klasse albeit I opted for a petrol engine I had comparable symptoms a while back Louder than normal exhaust noise especially noticeable during regeneration cycles The diagnostic also pointed towards the exhaust valves Did you check for any unusual vibrations or rattling sounds originating from the exhaust system itself

Interesting I have noticed no unusual vibrations but the louder exhaust noise is definitely there and most prominent after starting the engine Did your diagnostic specifically pinpoint the flap motor as the culprit or was it more of a general exhaust system error

The initial diagnostic indicated a malfunction within the exhaust system triggering the CEL Further investigation by a qualified technician using XENTRY diagnostics confirmed the defect originated within the flap motor itself I advise having it checked at a workshop A defective flap can lead to further complications

Thanks for the info I took it to the shop and you were spot on faulty flap motor 190€ later and it is sorted I appreciate the help
