What is the 2008-2013 BMW M3 E92 Rear Differential Mount and Subframe Stress?

The E92 M3's rear subframe has an inherent weakness - the factory differential mounts are too soft for the power and torque these vehicles produce. Over time, especially under hard acceleration or track use, the stock rubber bushings harden, shrink, and become brittle, allowing t… Repairs typically run $400-$2,000. Severity: medium.

What is the 2015-2023 BMW M3 S55/S58 Electric Water Pump Failure?

The S55 and S58 engines use electric water pumps rather than belt-driven pumps.

Failure can lead to overheating and potential engine damage if not addresse… Repairs typically run $800-$1,800. Severity: medium.

What is the 2021-2023 BMW M3 G80 S58 Engine Carbon Buildup on Intake Valves?

The S58 twin-turbo engine in the G80 M3 uses direct injection, which sprays fuel directly into the combustion chamber rather than over the intake valves. Oil vapors from the crankcase ventilation system deposit carbon on the backs of intake valves over time. Without fuel washing… Repairs typically run $500-$1,000. Severity: medium.

What is the 2013 BMW M3 2013 S65 Idle-Control-Device Warranty Extension?

BMW SIB 01 03 16 extends the engine idle control device limited warranty to 10 years or 120,000 miles for eligible US-specification model-year 2013 E92 M3 Coupes produced June 30, 2012 through June 27, 2013 and E93 M3 Convertibles produced February 22, 2012 through October 1, 201… Severity: medium.

What is the 1995-1999 BMW M3 Elevated oil consumption via crankcase ventilation (CCV) and rings?

S50/S52 M3s commonly consume oil with no external leaks and no visible exhaust smoke, typically in the range of about a half-quart to two quarts per 3,000 miles. The primary contributors are a failing crankcase ventilation valve (CCV/oil separator) that pulls oil vapor into the i… Repairs typically run $150-$700. Severity: medium.
