The fastening of the swirl flaps in the intake works loose from the vibration of the engine, and a flap can come away.
Applies to the engine M47D20TU2.
The swirl flaps in the intake manifold are held by screws, and engine vibration can work them loose beyond 120,000 kilometres.
Applies to the engine M47D20TU2.
The timing chain stretches from 180,000 km, and the chain tensioner no longer holds it properly.
Applies to the engine M47D20TU2.

2005–2011. The changeover year can fall in two generations. If the listing is from that year, look at the neighbour too.
No. It depends on the engine and the transmission too.
