Fuel tank leak on B46/B48 engines (2024); BMW repairs affected cars free under a service campaign.

BMW service campaign · NHTSA ID 11027759 · Jan 2026 · also written SI B16 02 25, B160225

What it covers

A service campaign is a fix BMW performs free on affected cars. Ask a BMW center whether it is open on your VIN.

The assembly cover on the left side of the fuel tank may not have been properly plastic welded. Thiscould lead to a smell of fuel after refueling or service engine soon light (MIL) for an evaporative leakin the fuel system.
