What is Fault Code P137A?

The BMW Fault code P137A, also known as “Knock Control Super Knocking Caused by Defective Ignition Coil”, is an indicator of severe engine knocking.

The presence of this fault code in your BMW may lead to damaging impacts on vehicle performance and longevity.

Signs and Symptoms of Fault Code P137A

Having the P137A Fault Code appear on your dashboard itself is a clear warning sign. However, other symptoms might manifest themselves, including reduced engine power and performance, abnormal or fluctuating engine idle speed, and the infamous ‘check engine’ light might even light up.

The Culprits Behind Fault Code P137A

Various issues may trigger the P137A fault code in your BMW.
