Application and Buying Notes

Alternators need to be matched carefully, because the electrical output and mounting style matter as much as the vehicle model. For this OEX unit, the key checks are 12V, 150A, Bosch style, part number BXA089, and OEM number BXA014. If your existing alternator or vehicle listing does not match those details, stop and verify before purchase.

The fitment information supplied with this item references BMW 5 and BMW X3 applications across the listed year range. That makes the part number check especially important, because the same model family can use different charging system components depending on engine, year, or production change. Compare the vehicle details, the alternator casing style, and the identification numbers on the old unit where possible.

The warranty is stated as 3 years for passenger use and 1 year for commercial use. That is useful when assessing the intended application, but it does not replace a fitment check. Commercial use can place greater demand on charging components, so confirming that the alternator is the correct specification for the vehicle is still essential.

If you are replacing an existing alternator, keep the old unit on hand until the new one is confirmed. The most reliable buying approach is to compare the part no. BXA089, the OEM number BXA014, the 12V 150A rating, and the Bosch style description against the removed component and the vehicle application data before final installation.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number BXA089 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

OEX Alternator 12V 150A Bosch Style. Part number BXA089 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number BXA089, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator passenger in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BMW 5, BMW 5 2003, BMW 5 2004, BMW 5 2005. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm fitment using the part number BXA089, OEM number BXA014, the 12V 150A Bosch style description, and the vehicle application details before ordering. If there is any difference in the existing unit or vehicle configuration, check carefully before fitting.
