Second Hand BMW i3 Parking Sensor

Yes, parking sensors were available on the BMW i3, though they were not standard on every trim level — they were offered as part of optional packages on certain specifications, so not every i3 on the road will have them fitted. If your car has sensors, they will be located in the front and/or rear bumper depending on the specification your vehicle was built with. Before sourcing a used sensor, it is worth confirming with your breaker that your specific registration was built with parking sensors, as a car without them from the factory will need additional wiring and modules that a simple sensor swap will not cover.

The BMW i3 ran from 2013 through to 2022, with a notable facelift arriving in 2017 that brought bumper styling changes, and this is where caution is needed — sensors from a pre-2017 car may not correctly align with or clip into a post-2017 bumper due to those bumper revisions. Within the pre-2017 (2013–2017) range or within the post-2017 (2017–2022) range, sensors are more likely to interchange, but the colour-match of the sensor cap is a cosmetic factor to be aware of with used parts. Confirm with your breaker that the donor car's year matches your side of that 2017 facelift boundary before purchasing.

The i3s, introduced in 2017, has wider bodywork and restyled bumpers compared to the standard i3, which means parking sensors from a standard i3 are unlikely to be a direct physical fit into an i3s bumper, and vice versa. The drivetrain difference between the two — the i3s has a more powerful motor — has no bearing on sensor compatibility whatsoever, as parking sensors are purely a body and wiring concern. Tell your breaker clearly whether your car is the standard i3 or the i3s so they can pull from the correct donor vehicle.

The REX variant carries a small petrol range-extender engine in addition to the electric motor, but this mechanical difference has no effect on parking sensor compatibility — the sensors sit in the bumpers and are entirely unrelated to the drivetrain layout. The relevant factors are the body style, the model year relative to the 2017 facelift, and whether the donor car had sensors fitted from the factory. You can safely ignore the REX or non-REX distinction when sourcing parking sensors.

The battery capacity upgrades BMW made to the i3 over the years — moving from 60Ah to 94Ah and then to the 120Ah pack — did not bring any changes to bumper or sensor design, so battery specification is irrelevant when sourcing parking sensors. What matters is the model year in relation to the 2017 facelift, and whether the donor vehicle was built with sensors. As long as your breaker is matching year and body style correctly, the battery variant is not something you need to mention.

The BMW i3 has a unique body construction using its carbon fibre reinforced plastic (CFRP) structure and purpose-built bumpers, so sensors from other BMW models such as the 1 Series or 3 Series are very unlikely to be a physical or plug-and-play match. Individual sensor elements can sometimes be electrically compatible within a brand's parts ecosystem, but bumper aperture sizing, clip design, and control module pairing make cross-model swaps unreliable. Stick to sourcing sensors from an i3 donor car and confirm year and variant with your breaker.
