All 4 Known Issues
On the 2024 BMW M3 CS S58 3.0L Twin-Turbo I6, the M3 CS uses the same Y-shaped plastic charge pipe found on the standard G80 M3, connecting both turbochargers to the throttle body. Despite the M3 CS producing 543 hp (higher than the standard M3 Competition's 503 hp), BMW retained the factory plastic charge pipe. Under sustained high-boost conditions, particularly during track use which the M3 CS is designed for, the plastic charge pipe can develop hairline cracks or blow off entirely. Heat cycling degrades the plastic over time, and the M3 CS's higher boost pressures accelerate this failure mode.
Common Symptoms
- Sudden total loss of boost pressure, especially at high RPM
- Loud pop or hissing from engine bay under acceleration
- Check engine light with boost pressure deviation codes
- Dramatic power loss above 3,000 RPM
- Turbo compressor surge noise
How to Fix
Replace the factory plastic charge pipe with an aluminum aftermarket unit from do88, FTP Motorsport, or VRSF. These direct-fit replacements handle higher temperatures and pressures without risk of cracking. If the car is under warranty and the failure occurs on stock tune, BMW should cover the repair. Inspect the charge pipe during every service and before track days.

Parts and tips from 85+ owners who fixed this issue
- NoteIf you plan to track your M3 CS (which is what it's built for), replace the plastic charge pipe with aluminum BEFORE your first track day. A blown charge pipe at 150 mph is not something you want to experience.
- UpgradeThe do88 cast aluminum charge pipe is the go-to upgrade. CNC-machined flanges, perfect OEM fitment, and rated for far higher boost than the S58 can produce.
On the 2024 BMW M3 CS S58 3.0L Twin-Turbo I6, the S58 twin-turbo engine uses direct injection exclusively, meaning no fuel washes over the intake valves to keep them clean. Oil vapors from the crankcase ventilation system deposit carbon on the valve backs over time, restricting airflow and reducing performance. The M3 CS's higher boost pressures and more aggressive driving style can accelerate carbon accumulation. While the S58 has improved crankcase ventilation over the older S55, carbon buildup remains an inevitable maintenance item on all direct-injection engines.
Common Symptoms
- Gradual loss of throttle response and power
- Rough idle that develops over time
- Slight misfires at idle, especially when cold
- Reduced fuel efficiency compared to when new
- Hesitation during low-RPM acceleration
How to Fix
Schedule walnut blast cleaning of the intake valves at 40,000-50,000 mile intervals. Install an oil catch can to reduce oil vapor entering the intake system. Use high-quality synthetic oil meeting BMW LL-01 specification and change at 5,000-7,000 mile intervals. Allow the engine to fully warm up before high-boost driving to ensure proper oil vapor management.

On the 2024 BMW M3 CS S58, the 2024 M3 CS makes 543 hp from its S58 twin-turbo inline-6, the highest output of any G80 M3 variant. The OEM plastic charge pipe (intercooler to throttle body) can develop cracks under sustained high-boost driving, particularly on track. The CS-specific higher boost calibration pushes the plastic pipe beyond its fatigue life sooner than the standard M3. A cracked charge pipe causes an immediate and significant loss of boost pressure.
Common Symptoms
- Sudden loss of power under hard acceleration
- Boost pressure not reaching target (visible on OBD scanner)
- Whooshing or hissing sound from engine bay under load
- Check engine light with boost pressure deviation codes
- Limp mode activation during spirited driving
How to Fix
Replace the OEM plastic charge pipe with an aluminum or reinforced charge pipe from VRSF, Eventuri, or BMS. The aluminum pipe eliminates the cracking risk entirely and is a 30-minute DIY job. If the OEM pipe has cracked, also inspect the intercooler boots and couplers for damage from over-pressurization.

On the 2024 BMW M3 CS S58 3.0L Twin-Turbo I6, the M3 CS uses BMW's iDrive 8 system with a large curved display, which some owners report experiencing random screen blackouts, system reboots, and software glitches. Issues include the screen going completely black while driving, stereo cutting out mid-playback, phone connectivity failures with Apple CarPlay/Android Auto, and instrument cluster warnings that resolve on restart. These issues are more common on early production vehicles and are typically resolved through BMW software updates.
Common Symptoms
- iDrive screen going completely black while driving
- Audio system cutting out and requiring restart
- Apple CarPlay/Android Auto disconnecting frequently
- Instrument cluster showing spurious warning messages
- Touch screen unresponsive or laggy
How to Fix
Check for and install the latest BMW iDrive 8 software updates, which can be delivered over-the-air or at a dealer. Perform a soft reset by holding the iDrive controller button for 30 seconds. If screen blackouts persist, the dealer may need to replace the head unit or update the gateway module firmware. Ensure the 12V battery is in good condition, as low voltage can trigger software instability.
