For a long time, I am hearing this clicking sound. I always though it was exhaust cooling after FAP regeneration. But I am not so sure anymore, since I can hear it even when car is not doing it. I found a video of exact same thing on reddit:
Anyone has an idea what it could be? My mechanic is not sure, he thinks it's inside exhaust. I went to some exhaust repair place, they think FAP filter is almost done, but I am not so sure. They all "think" it could be something, but don't stand behind it.
The car is Peugeot 308 T9, 2.0 HDI 110kw, year 2015.
