2013-17 BMW F33 4-Series Convertible: Takata airbag recall
In December 2018, a staged recall campaign was initiated for BMW ‘F Series’ models – this included 2013-17 BMW F33 4-Series Convertible vehicles. These vehicles had Takata driver’s airbags and the propellant wafers in these airbags could absorb moisture over time. In the event of airbag deployment, excessive internal pressure could cause the metal inflator housing to rupture and metallic fragments could be projected through the airbag cushion towards vehicle occupants – these fragments posed a risk of serious injury and fatality. For the VINs of the recalled vehicles, please see PRA 2018/17191.

2014 BMW F33 420i, 428i and 435i: ‘Service Engine Soon’, ‘Drivetrain Malfunction’ and VANOS faults
In September 2014, BMW North America issued Service Bulletin SI B12 26 14 for BMW F33 420i, 428i and 435i Convertibles that were manufactured prior to July 2014. These vehicles may exhibit the following symptoms:
- Illumination of the ‘Service Engine Soon’ warning (Malfunction Indicator Light);
- The engine may enter a reduced power mode with the ‘Drivetrain Malfunction’ message displayed; and,
- One or more VANOS faults may be stored in the DME, even though the engine is mechanically sound and no unusual noises can be heard from the VANOS area. These VANOS faults related to implausible camshaft position (intake or exhaust), the camshaft stuck situation, or the camshaft angle offset relative to the crankshaft being outside the tolerance range.
According to the service bulletin, these symptoms could be due to unfavourable Engine Position Management (EPM) parameters in the DME software. The service bulletin recommended test plans be performed using BMW’s ISTA/D diagnostics system and any VANOS hardware issues were to be corrected. After performing repairs, or if the ISTA test plan was inconclusive, the vehicle’s DME software was to be re-programmed with the latest version of ISTA/P. If further VANOS control faults occurred after the DME software was updated, further diagnosis would be required to identify its cause.
