The BMW Longlife-17 FE+ approval is intended specifically to reduce the risk of LSPI. LSPI stands for low speed pre-ignition and means that the mixture ignites spontaneously in the combustion chamber at low speeds before the ignition spark.
This can lead to motor knocking and therefore serious motor damage. This phenomenon is entirely understood yet. But this risk can be reduced by using the right motor oil.
