Clarity Loud Exhaust After Cold Start

I have a 2018 Honda Clarity hybrid with 248702 km. Recently, the exhaust is louder than usual, especially after cold starts, and the engine sounds a bit noisy. I also found an error stored. Could it be the exhaust flaps? Anyone else experienced something similar?

A 2018 Honda Clarity hybrid owner reports a loud exhaust noise, especially after cold starts, and a stored error code. The issue may be related to malfunctioning exhaust flaps or a blockage. A suggestion is made to check the flap motor, but the owner is advised to visit a workshop for a proper diagnosis and repair.

Did this summary help you solve your problem?

Louder exhaust noise points to a potential exhaust blockage or exhaust flaps malfunction. Have you checked the flap motor? I had a similar issue - is your engine performance noticeably different?

I haven't checked the flap motor specifically. Where exactly is it located, and how would I test it? And what do you mean by a noticeable difference in engine performance? What kind of difference?

I did not check it myself. Given the symptoms, particularly the stored error and noise, and the possibility of a defective exhaust flap, a visit to a workshop for diagnosis is highly advisable. This was my course of action. The eventual repair cost 190€

Thanks a lot for the advice! It seems like a trip to the workshop is the best course of action. I'll post what I learn about the defective exhaust flaps.
