BMW i7 Brake Servo Replacement Parts

The BMW i7 is a fully electric vehicle and does not have a conventional vacuum-assisted brake servo; instead it uses an electro-hydraulic brake booster system (sometimes called an iBooster or electrohydraulic unit) that generates braking force electronically without needing engine vacuum. This means if you are searching for a traditional brake servo, that part simply does not exist on the i7. What you are most likely looking for is the electrohydraulic brake booster or brake pressure modulator unit — confirm the exact part description with your breaker against your registration number.

The BMW i7 (G70) launched in 2022 and is currently in its first generation, so there is no facelift or second generation to cross yet; within that single generation, fitment is more consistent, but software calibration and subtle hardware revisions can still vary by build date and xDrive versus RWD variants. Always confirm the part number on the unit against your registration with the breaker before purchasing. Never assume fitment is guaranteed even within the same generation.

Trim and badge level alone do not determine fitment, but the underlying drivetrain and power output do matter — the high-performance M70 variant carries significantly larger brakes and a different brake system setup to the eDrive50 or xDrive60, so the brake booster units are not necessarily interchangeable across those variants. The eDrive50 (rear-wheel drive) and xDrive60 (four-wheel drive) may also differ due to the additional front axle motor on the xDrive. Tell your breaker your exact variant and registration so they can match the correct electrohydraulic unit rather than going by trim name alone.

Some breakers and listings use 'brake servo' as a catch-all term even on electric vehicles where a traditional vacuum servo was never fitted, so the listing may genuinely refer to the electrohydraulic brake booster that performs the same function on the i7. Before buying, ask the breaker to confirm the part number and that it is the electro-hydraulic unit rather than a conventional vacuum servo, because fitting the wrong type would be a safety-critical error. Always verify against your registration.

BMW does share some electro-hydraulic brake components across its EV platforms, but the iX (G06) and i7 (G70) are different vehicle architectures with different weights, brake system configurations, and software integration requirements, so cross-model fitment is not something to assume. This is a safety-critical component, so even if a unit looks physically identical, confirm part numbers and compatibility directly with your breaker against both registrations before purchasing. Never fit a brake system component without verifying it is the correct specification for your exact vehicle.
