Recall campaigns
Heavier after 2008
In 2008 and 2009, engines were replaced under warranty due to connecting rod breakage from defective bolts. In engines after 2011 with Delphi Common Rail, the fuel pump often produced metal shavings.
Burning of washers under injectors
Often reported
The most known failure of this diesel is burning of copper washers under injectors, leading to rapid coking of the engine with very sad consequences.
Clogged oil pickup
Often reported
Another common problem is a clogged oil pickup. It is advisable to check it periodically, otherwise the bearings may spin unexpectedly.
Low timing chain lifespan
Often reported
The timing mechanism consists of three chains, the weakest being the lower one that drives the oil pump and balancers. Its breakage usually also tears the main timing chain.
Other weak points
Often reported
Other components with limited lifespan include crankshaft bearings, hydraulic lifters, vacuum control system, turbocharger geometry adjustment, and EGR valve.
