Original BMW 40mm Windshield Cowl Access Plug for BMW 2 Series, 3 Series, 4 Series, M3, M4, X3, and X4 (2006–2021)

On the F30 3 Series and its relatives, this 40 mm Original BMW plug closes the access hole in the windshield cowl cover that sits over the strut brace bolts. Pull the plug and you can reach those bolts without taking the cowl cover off. BMW calls it simply a plug, 40 mm in diameter, and it weighs only 4 grams. It is made in Germany and sold individually. This plug often goes missing on used cars. Because it is available on its own, an open hole in the cowl does not require buying a whole new cowl cover. Production of this number began in September 2010.

Original BMW Parts carry a 24-month parts warranty.

BMW uses the same plug across a wide spread of chassis. These include the F22 and F23 2 Series, the F30 sedan and F34 Gran Turismo 3 Series, the F80 M3, the F32, F33, and F36 4 Series, the F82 and F83 M4, the F25 X3, and the F26 X4. Facelift versions of each carry the same number, so a 2016 320i and a 2018 340i take an identical plug. That is useful if you own more than one of these cars or are sorting a box of loose trim pieces.

Common Questions

No. The plug is sold by itself and fits into the existing cowl cover.
