The 2010 to 2016 BMW 550i is a high-performance executive sedan that shares the N63 4.4L twin-turbo V8 with the 750i, X5 xDrive50i, and 650i. This engine’s well-documented oil consumption problem — caused by valve stem seal failure from the hot V turbo layout — is one of the most commonly repaired issues at Auto Imports.
THE N63 OIL CONSUMPTION PROBLEM IN THE 550i
- Hot V turbo placement exposes valve stem seals to extreme heat
- Seals degrade and allow oil into combustion chambers
- Blue or grey exhaust smoke — worst on cold startup and deceleration
- Oil level drops between changes — often 1 quart per 600–1,500 miles
- Spark plug fouling, misfires, and catalytic converter damage follow
ALSO WATCH FOR THESE N63 ISSUES
- Turbocharger wastegate rattle — both turbos typically replaced together; $4,000–$8,000
- Timing chain tensioner wear — rattle on startup; $2,000–$3,500
- Fuel injector failure — all six may need replacement; $400–$600 each
- Battery drain — active cooling system drains battery post-shutdown; replacement every 20,000 miles recommended by BMW
AFFECTED 550i MODELS
- 2010–2016 BMW 550i Sedan (F10) — N63/N63TU
- 2010–2013 BMW 550i Gran Turismo (F07)

FREQUENTLY ASKED QUESTIONS
Q: Does the BMW 550i have oil consumption problems?
A: Yes. The 2010–2016 BMW 550i N63 V8 is one of BMW’s most oil-prone engines. Valve stem seal failure from the turbo’s extreme heat is the root cause. BMW launched a Customer Care Package in 2014 and a class action resulted in extended coverage for qualifying vehicles.
Q: What year 550i has the worst problems?
A: The 2010–2013 models with the original N63 (not TU) are the most problematic. The N63TU (2014+) received engineering updates, but oil consumption and related issues persist across all generations.
Q: How much does 550i N63 valve seal repair cost in Edmonton?
A: At Auto Imports, valve stem seal replacement on the N63 550i typically ranges from $5,000 to $9,000. The engine must be dropped from the vehicle to access the seals properly.
