# Service bulletin B160321

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## Other bulletins for the same vehicles and component

- [B610321](/bulletins/10250893.md), 2024-03-02, Service bulletin: ELECTRICAL SYSTEM; FUEL SYSTEM, GASOLINE:STORAGE:EVAPORATIVE EMISSIONS:CANISTER; ELECTRICAL SYSTEM:SOFTWARE. SITUATION BMW AG is conducting a Voluntary Emissions Recall \(effective April 23, 2021\) on a certain Model Year 2020 \- 2021 BMW vehicles that were produced between August 13, 2019 and December 11, 2020. Do not deliver to a customer, a New, Certified Pre\-Owned or Used vehicle subject to an emissions recall, until the vehicle is repaired. Do not use or sell replacement equipment/parts subject to an emissions recall. The 12 V battery’s dual storage system \(DSS\) may contain a software error which intermittently causes a continuous resetting of the microcontroller and communication failure. The error is displayed by a red Check Control message.
- [B160123](/bulletins/10249015.md), 2024-02-01, Service bulletin: FUEL SYSTEM, GASOLINE. A vehicle arrives at your center to be diagnosed for a micro\-leak in the fuel evaporative \(EVAP\) system\(NVLD natural vacuum leak detection\). For this condition, the following fault is stored in the DME: 190302 \- fuel tank ventilation and scavenging air system, micro\-leak: leakage more than 0.5mm For: Model vehicles other that the ones listed above, or for EVAP faults related to a “large leak,” after confirming that the fuel filler cap is fitted properly, then, proceed to follow the corresponding test plan
- [B160623](/bulletins/10247567.md), 2024-01-03, Service bulletin: FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING. Engine will crank but not start. There is no communication with the integrated fuel module \(TFE\) whendiagnosing with ISTA. The following two fault codes will be stored in the DME: 032B43 \- Low fuel pressure system, electric fuel pump: pressure value too low CDA594 \- Message \(\- 0x33E\) missing, receiver DME, transmitter TFE
- [B160123](/bulletins/10239602.md), 2023-07-24, Service bulletin: FUEL SYSTEM, GASOLINE. A vehicle arrives at your center to be diagnosed for a micro\-leak in the fuel evaporative \(EVAP\) system \(NVLD natural vacuum leak detection\). For this condition, the following fault is stored in the DME: 190302 \- fuel tank ventilation and scavenging air system, micro\-leak: leakage more than 0.5 mm.
- [SIB170220](/bulletins/10224198.md), 2022-10-17, Service bulletin: FUEL SYSTEM, GASOLINE; SERVICE BRAKES; ENGINE AND ENGINE COOLING. Symptom 1: There are traces of coolant leaking under the vehicle, or there is significant pressure released along with coolant loss when opening the low temperature cooling system reservoir \(engine cold\). The following fault code may also be stored in the DME: 20A201 \- Charge air cooling system: Coolant pump protective function activated due to dry running Symptom 2\*: The air conditioning may have low cooling output with the following fault stored in the IHKA: 80120A \- Compressor: Shut down due to overpressure in refrigerant system. Symptom 2 is an additional symptom related to Symptom 1. Diagnose the IHKA fault with ISTA test plans if it is the only fault stored \(if no DME faults are stored related to coolant loss, this bulletin repair does not apply\).
- [SIB160222](/bulletins/10218412.md), 2022-08-22, Service bulletin: FUEL/PROPULSION SYSTEM. The fuel gauge may indicate the incorrect fuel level \(full and reserve\).
- [B110521](/bulletins/10212784.md), 2022-05-31, Service bulletin: FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING. The belt pulley on the mechanical coolant pump may fracture allowing the engine drive belt to come off the coolant pump and alternator.
- [B160122](/bulletins/10211852.md), 2022-05-16, Service bulletin: FUEL SYSTEM, GASOLINE:STORAGE:EVAPORATIVE EMISSIONS:HOSES/VALVES/SENSORS; ENGINE AND ENGINE COOLING. During manufacturing, the evaporative lines for the EVAP system may have been routed incorrectly. This could result in a Service Engine Soon \(MIL\) lamp turning on.
- [B110521](/bulletins/10208176.md), 2022-02-22, Service bulletin: ENGINE AND ENGINE COOLING; FUEL SYSTEM, GASOLINE. The belt pulley on the mechanical coolant pump may fracture allowing the engine drive belt to come off the coolant pump and alternator.
- [SIB160221](/bulletins/10204622.md), 2021-12-13, Service bulletin: FUEL SYSTEM, OTHER:FUEL FILTER; FUEL SYSTEM, OTHER:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS. The hose clamp connecting the fuel filler pipe to the fuel tank may have been positioned incorrectly. Furthermore, owing to its larger outer diameter, the filler pipe installed in the vehicle cannot be positioned up to the end position in the connecting hose.
