Listed from most frequently reported, each with its source.
Many users and technical reports indicate abnormal oil consumption in the 4.4 V8 N63 engine used in the Serie 7 G11 LCI. The issue may appear after tens of thousands of kilometers, requiring frequent oil top-ups, and can cause blue smoke from the exhaust under certain conditions and risk of engine damage.
Engine Internal
Frequent oil leaks are reported due to deteriorated gaskets and components: valve covers, oil filter housing, and turbocharger oil circuit hoses.
Engine Internal
The crankcase ventilation system (PCV/CCV) can become blocked or fail, increasing internal pressure and allowing oil vapors to enter the intake system, leading to carbon deposits on intake valves.
Engine Internal
The N63 engine family has historically shown wear issues in timing chain guides and tensioners. Typical symptom is a rattling noise when cold or on startup; as guides deteriorate, the chain can stretch and in extreme cases jump timing, causing engine damage.
Timing chain
The N63 engine's hot-V layout exposes turbochargers to very high temperatures; oil passages and returns can become blocked or degraded, leading to coking, inadequate bearing lubrication, and turbo damage.
