BMW 4 Series Towbar Replacement Parts

Yes, BMW did offer factory-approved towbar options for the 4 Series, and aftermarket towbars were also produced for it, so used towbars do exist for this model. However, fitment depends heavily on which generation and body style you have, as the 4 Series has gone through distinct platform changes. Always confirm with the breaker that the towbar they have is approved or designed for your exact variant.

No, the F-series (F32 coupe, F33 convertible, F36 Gran Coupe, 2013–2020) and G-series (G22, G23, G26, 2020 onwards) are entirely different platforms with different underbody and rear subframe structures, so towbars are not interchangeable between them. This is one of the clearest fitment boundaries on the 4 Series, and crossing it will not work. Make sure you and the breaker confirm which generation your car is before agreeing a purchase.

Yes, body style is the first question here, because the rear body structure, bumper mounting points, and underfloor geometry differ between the two-door coupe (F32/G22), convertible (F33/G23), and four-door Gran Coupe (F36/G26). A towbar designed for one body style will not simply bolt onto another, even within the same generation. Always tell the breaker your exact body style alongside the year so they can match the right towbar.

Trim level does not change the fundamental fitment of the towbar itself, as the structural mounting points are the same across SE, Sport, M Sport, and other trim grades within the same generation and body style. However, M Sport and some other trims have different rear bumpers with different apertures or trim pieces, which can affect how a towbar neck emerges through or beneath the bumper, and whether a particular towbar's wiring or swan-neck will sit correctly. Confirm with the breaker that any cosmetic or bumper differences between their donor car's trim and yours won't cause a problem.

Both 2014 and 2017 fall within the first-generation F-series 4 Series (2013–2020), so they share the same platform and you are broadly on the right track. However, there was a facelift applied to the F-series range during this period, and pressing or underfloor detail changes between pre- and post-facelift cars are something to confirm with the breaker against your registration rather than assume. If the body style also matches, the chances of compatibility are reasonable, but only the breaker can confirm definitively by checking the part against your reg.

The 4 Series shares its platform with the contemporary 3 Series — for example, the F32 4 Series is related to the F30 3 Series — but the body structures diverge significantly at the rear, and the rear subframe, bumper, and floor geometry are not identical between the saloon or estate 3 Series and the coupe or Gran Coupe 4 Series. A towbar built for a 3 Series is very unlikely to be a straight swap, and you should not assume compatibility even though the engines and front ends share components. Raise this question directly with the breaker, giving them both registrations, and let them advise.
