Automatic Start/Stop Eliminator Deactivation Module for BMW 8 Series G14/G15 (2018-2025)

Automatically Disable Your BMW's Stop/Start Functionality

The BMW 8 Series G14/G15 was built with one priority above all others: the drive. A true Grand Tourer in the tradition of the original E31, the 8 Series combines genuine performance with a level of luxury that makes every mile feel intentional. Whether you're behind the wheel of an 840i Coupe or an M8 Competition Convertible, the 8 Series isn't transportation — it's the reason you took the long way home.

The factory Start/Stop system doesn't belong in that equation. A GT built for flowing roads and uninterrupted driving pleasure shouldn't cut its engine at a traffic light. With a twin-turbocharged inline-six or a 617hp V8 under the hood, that interruption is more than an inconvenience — it's a contradiction.

Our electronic module removes it, automatically, every time you start the car:

→ The Start/Stop system is deactivated at every ignition cycle — no button press required, no exceptions.

How Does It Work?

Install once, forget about it forever. The module stores your preference and applies it at every startup without any input. The 8 Series fires up, the engine stays running, and the drive begins exactly the way it should.

Want to return to factory behavior?
→ Press the original Start/Stop button at any time. No coding, no permanent changes, no trace left on the vehicle.

Why Disable Start/Stop on Your BMW 8 Series G14/G15?

Every engineering decision in the 8 Series was made in service of the driving experience. The Start/Stop system is the exception:

• Engine cuts at every stop — at odds with the continuous power delivery a GT is built around
• Restart vibrations that break the cabin composure the 8 Series works hard to achieve
• Additional strain on the battery and starter across every urban cycle
• Hesitation on pull-away from a standstill — noticeable on high-output variants
• On the G14 Convertible: engine shut-offs are more perceptible top-down and interrupt the exhaust note entirely

With this module, the engine stays running. The 8 Series delivers what it promised when you bought it — every time, without compromise.
