All 1 Known Issues
On the 2017-2025 BMW 4 Series B58, the plastic charge pipe (intercooler to throttle body) on B58-powered 440i and M440i models can pop off or crack under high boost pressure, especially in warm weather or during spirited driving. The OEM plastic pipe uses a pressed-on connector that weakens over heat cycles. When the pipe disconnects, the engine immediately loses boost pressure and enters limp mode with significant power loss.
Common Symptoms
- Sudden loss of power during hard acceleration
- Loud pop or hissing sound from engine bay
- Boost pressure fault codes stored in DME
- Check Engine light with underboost code
- Engine running rough after the pipe disconnects
- Whistling or whooshing noise under throttle
How to Fix
Replace the OEM plastic charge pipe with an upgraded aluminum aftermarket unit. These use proper clamp-style connections that won't pop off under pressure. If replacing with OEM, use the latest revision part number. Check the intercooler boots and couplings for damage from the pressure release event.
