The Problem: OEM Crank Hub Failure
BMW’s factory S55 crank hub design is prone to slipping, especially when tuned or driven hard. This leads to:
❌ Misaligned timing
❌ Check engine lights & limp mode
❌ Potentially severe engine damage
❌ Fault codes 130E20 and 130F20
We know first hand that this can happen – we’ve experienced the problem on Craig’s M4. We’ve also upgraded the hub on our demo M2 comp.
