- Increased stress on the AGM battery and starter motor
- Engine stops before optimal turbo lubrication
- Perceptible jolts in the BMW premium cabin
- Risk of stalling during maneuvers and tight parking

With our module:
➡ The engine remains available at all times for a smoother, more comfortable drive, suited to the sporty character of the 3 Series .
