LEIB Engineering CAN MIL Deleter for BMW F & G Series Plug & Play CANBUS CEL/MIL Delete Module, Check Engine Light Suppressor for Decat, Sports Cat & GPF/OPF Mods E1 Approved & CE Marked, No Coding, Off‑Road/Track Use

LEIB Engineering CAN MIL Deleter - BMW F Series and G Series

Tired of the engine warning lamp after exhaust upgrades. The LEIB Engineering CAN MIL Deleter is the smart, plug-in CAN bus solution that keeps the dashboard clear of emissions-related alerts once you have fitted a catless downpipe, 200-cell high-flow catalyst or removed the OPF GPF on BMW F Series and G Series vehicles. E1 approved and CE marked, it works seamlessly with the factory electronics and does not need coding, remapping or a tune.

Why enthusiasts choose this module

• Stops emissions and catalyst efficiency warnings that appear after decat, high-flow sports cat or OPF GPF changes
• Blocks nuisance emissions-related DTC entries so the engine management light stays off
• OEM-quality plug-in harness with automotive connectors - fully reversible fit
• E1 approval and CE mark for integrity on the vehicle CAN bus
• No ECU flash, no software, no coding - just connect and go
• Keeps factory diagnostics and safety systems intact
• Automatically deactivates when a BMW dealer tester is connected for servicing
• Typical fitting time around 30 minutes with an illustrated guide included

How it works

The module integrates with the BMW CAN network and filters the emissions-related messages that would otherwise trigger the malfunction indicator. There is no wire cutting and no invasive splicing. It simply plugs in with OE-style connectors, providing a clean, reliable, track-focused way to prevent catalyst and particulate filter warnings after exhaust hardware changes.

Compatibility

Designed for BMW F Series and BMW G Series models where the catalytic converter or OPF GPF hardware has been altered. Ideal for vehicles running a catless downpipe, 200-cell sports catalyst, high-flow catted system or OPF GPF delete sections that commonly cause engine warning lights.

Important: if the OPF GPF is removed, the DELETE-R is also required.
