Questions about these listings
Which model years are named in the listings for BMW X4 oxygen sensors?
4 listing titles give model years from 2015 to 2024. Check your car’s year against the fitment details in each listing.
Which positions are named in the listings for BMW X4 oxygen sensors?

Which part numbers appear in more than one listing for BMW X4 oxygen sensors?
234-5054 appears in more than one title. Compare the number on your old part with the listing before you buy.
How do I check fitment before buying BMW X4 oxygen sensors?
Find which sensor has failed. Upstream sensors sit before the catalytic converter and control fuelling; downstream sensors sit after it and monitor the converter. A fault code that names the bank and sensor number identifies the position. Some engines use a wideband (air-fuel ratio) sensor upstream. It is not interchangeable with an ordinary oxygen sensor, so match the type as well as the position.
Check compatibility before buying
These listings were found using BMW X4 oxygen sensors search terms. A search match does not establish fitment. Compare the part number, vehicle year, generation and engine with the seller's compatibility details. Confirm delivery, returns and the final price on eBay before ordering.
