Excessive thermal load from the EGR system on the intake components 2. An excessive or unmetered air leak in the intake/charge air system
B1116152018-12-10. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. N20 and N26 engine: Smoke from Exhaust when Starting a Cold Engine.

1202142018-11-13. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL. Service Action: Program Control Units (Fuel Shut-off Valve). Due to a software error, it is possible that a Check Engine light (MIL) may not be illuminated after a fault is detected at the fuel shut-off valve (TAV). This is an emissions-relevant fault.
1105142018-11-13. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE. S63TU Engine: Noises from Leaking Exhaust Manifold.
