Noise or rubbing under the car and water on the front carpet from a loose air-conditioning drain (BMW 2 Series Gran Coupé, X1 and X2)

Engine / equipment

BMW 2 Series Gran Coupé (F44), X1 (U11) and X2 (U10)

Period mentioned

2025 (US model years)

Symptoms

A noise from under the car or a feeling of something rubbing that is transmitted into the body while driving; water may appear on the front carpet.

Possible cause described

The two-piece air-conditioning evaporator drain was not fully locked together when assembled and has come apart; the lower half bounces around under the car. BMW replaces that half with the correct part (bulletin SIB 64 08 26). Both halves have a new design from 28/2/2025.

Check for the garage

Ask the workshop to check whether the lower half of the evaporator drain is missing; both halves must be of the same design (old or new), never mixed.
