Known issues for this car

Before you buy this car

From the generation guide

1. Recall check by VIN. Ask a BMW dealer to check the VIN for open campaigns: the 330e battery (2020 cars), the starter, the 48-volt starter-generator cables, the brake discs and the front belt buckle. Bad result: an open campaign, or no record of the work.
2. Steering knocks. Drive slowly at full lock in both directions, then over a few bumps. Bad result: a knock or creak from the rack or the joints.
3. Suspension (needs a lift). Ask a workshop to lift the car and check the ball joints and bushings for play. Bad result: play in a ball joint or worn bushings.
4. iDrive. Start the car cold and check that the screen comes on within about 20 seconds, Bluetooth pairs and the navigation runs. Bad result: a reboot, a dropout or a frozen screen.

From the gearbox guide

1. Read the gearbox fault memory with a BMW-capable scanner. Bad result: pressure or solenoid codes such as 4F84, 4F87, P189C or P0748, or a past limp mode.
2. Ask for fluid and filter invoices. Bad result: no fluid change by 80,000 to 120,000 km, or a change without an adaptation reset.
3. Drive the car from cold and select Drive and Reverse. Bad result: a hard 1-2 shift, or a delay of 1-3 seconds before the gear engages.
4. Drive 15 minutes in town, then under load. Bad result: jerky 2-3 shifts, flaring, slipping or a burnt smell.
5. Hold a steady light throttle at low speed. Bad result: a shudder or vibration, which points to the torque converter lock-up clutch.
6. Look under the car on a lift. Bad result: oil at the wiring connector on the case, on the plastic pan or on the cooler lines.
