Is your BMW M5 showing signs of engine knocking noise? GarageNation specialises in diagnosing and repairing this problem on the BMW M5 (Sedan, Petrol) in Hyderabad. Urgency: Immediate. This is an immediate concern — do not continue driving until diagnosed. Estimated repair cost: ₹5,000 – ₹2,00,000.
The BMW M5 uses a 4.4 S63 V8 twin-turbo (600 bhp) and is classified as a sedan. Based on our workshop experience with BMW M5 in Hyderabad: S63 V8 valve stem seal oil consumption — same family as N63 but in higher state of tune. BMW M5 models are among the brands we see most frequently for engine knocking noise repairs.
Change engine oil every 10,000 km with the correct viscosity — degraded oil loses film strength and bearing clearances widen within one missed service.
Is engine knocking serious?
A deep metallic knock is one of the most serious engine sounds — it means bearing clearances have opened up and the crankshaft is hitting the bearing shells. Continued driving risks a spun bearing or broken connecting rod (₹1,00,000–₹2,00,000 repair or write-off). Stop immediately, check the oil level, and call GarageNation for free towing: +91 8106316369.
What causes engine knock on cold start?
Cold-start knock that clears after warm-up is almost always the timing chain tensioner losing hydraulic pressure overnight (oil drains back from the tensioner). This is a 'soon' repair (not emergency), but delaying it risks the chain jumping a tooth and causing catastrophic valve/piston damage. Most common on BMW N20/N46, VW EA888, and Maruti K-Series.
