Chain rattle cause M111 after start-up
If you see a dent at the bottom, this is the cause. Filter from Mann or Bosch or similar do not have a stiff plate as Hengst filter have (OEM). A valve at the bottom is not fully closed and the oil is drained over night.
When you start in the morning, the filter housing must be filled again leading to oil pressure drop and chain rattle.
The filter housing was constructed by Hengst and the Hengst filters have a stiff plastic sheet on both sides and they are not expensive too.
