Diagnosis and Common Symptoms
As the senior technician at M.S. Motor, I've seen countless ignition issues on classic M20 and M30 engines. The Bosch ignition control unit is the brain of this system, and when it fails, the symptoms are often mistaken for a bad coil or crank sensor. A primary indicator is a sudden no-start, no-spark condition, especially when the engine is warm. You may also experience intermittent stalling, where the vehicle runs perfectly and then cuts out, only to restart after cooling down. Unlike modern ECUs, this module will not store specific fault codes on your dash; diagnosis is a process of elimination, and verifying spark at the coil is a critical first step.
Introduction
Restore the reliable spark your classic BMW demands with a Genuine, road-tested Ignition Control Unit. Pulled from a running vehicle by our specialists, each module is bench-tested to ensure it delivers a consistent and correct signal output. We understand that for these vintage models, using original Bosch electronics is crucial for maintaining the vehicle's authentic performance and character. This is not a reproduction part; it's the real-deal component your E28 or E23 was born with.
