Disadvantages of the M276 DE30 engine
The timing chain tensioners are this power unit’s most troublesome component.
You will need to replace the timing kit with phase regulators if you overlook their failure.
Impulse disks on camshafts are frequently displaced on these engines as well.
Injectors that use direct injection are sensitive to the fuel’s quality.
On specialized forums, a few instances of scuffing caused by catalyst crumbs have been reported.
