Known issues for this car

Before you buy this car

From the engine guide

1. Chain (cold-start test, invoice). Listen for a rattle on a cold start. Ask for a chain job invoice. Bad: a rattle, or no chain record past 100,000 km.
2. Damper (look under the pulley). Check the rubber ring of the crankshaft pulley for cracks or a loose ring. Ask for a damper replacement receipt. Bad: visible cracks, or no record on a car over 100,000 km.
3. EGR recall (check the VIN). Check the VIN with a BMW dealer or the KBA recall list (reference 008124). Bad: an open campaign, or a cooler replaced with no record.
4. Swirl flaps and intake (ask for records). Ask whether the intake was cleaned and the flaps checked. Bad: no record at about 100,000 km, or a flap removed with no proof.
5. EGR and flap faults (scanner needed). Read the fault memory for EGR or swirl flap errors. Bad: any such error, or the engine warning light.
6. Oil history (paperwork). Check the service book for regular oil changes. Bad: long gaps between oil changes.

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.
