Second Hand BMW 4 Series Washer Pump

The BMW 4 Series (F32/F33/F36) ran from 2013 to 2020, so both a 2014 and a 2018 car fall within the same generation, which is a good starting point for compatibility. That said, whether the pump physically interchanges can depend on which reservoir and bonnet layout your specific car has, so confirm with the breaker against your registration before buying.

Yes, all variants of the BMW 4 Series are fitted with a windscreen washer pump as standard — it sits in the washer fluid reservoir in the engine bay and supplies fluid to the front and, where fitted, rear or headlight washers. This is a universal fitment across the range regardless of engine or drivetrain.

Trim level does not affect washer pump fitment — the pump and reservoir setup is the same whether your car is an SE, Sport, M Sport, or M Sport Pro. You may find cosmetically different reservoir caps or brackets, but the pump itself should be interchangeable, so don't rule out a pump from a different trim.

On BMW 4 Series models with a rear wash-wipe, the front and rear washer pumps are typically separate motors that sit on the same reservoir, running at different pressures, so they are not the same part. When getting a quote from a breaker, make sure to specify whether you need the front pump or the rear pump to avoid getting the wrong one.

The F32/F36 4 Series shares its platform and many components with the contemporary F30 3 Series, and the washer pump and reservoir can often be the same part across both models. However, this is not guaranteed, so give the breaker your exact registration and let them cross-reference the part number before purchasing.

The F3x-generation 4 Series ran through to 2020, so a 2019 car is still within the same generation as cars built from 2013 onwards. Washer pumps from earlier in the same generation are likely compatible, but confirm with the breaker against your registration as late production changes can occasionally affect ancillary parts like this.
