Bmw 3Aa-32Eu44A, 3Aa-12Et44, 3Aa-42Ex44, 3Aa-32Em44, 3La-22Cs44. Published by MLIT as 1239690 on 8 May 2025. Part: コンピュータ(エンジン).

What the notice says Dme(エンジン制御システム全体を統括する電子制御ユニット)の車載式故障診断装置の診断プログラムにおいて、設計検討が不十分なため、可変バルブ機構(バルブトロニック)関連の異常を検出した際に診断情報がメモリに保存されず、失われることがある。また、酸素センサー等の関連する部品の故障を同時に検出した場合、それらの診断情報も失われて警告灯が点灯しないおそれがある。そのため、関連部品の故障により排気ガスの量が増加した場合に検出できず、保安基準に適合しないおそれがある。

What the ministry says is wrong

DME(エンジン制御システム全体を統括する電子制御ユニット)の車載式故障診断装置の診断プログラムにおいて、設計検討が不十分なため、可変バルブ機構(バルブトロニック)関連の異常を検出した際に診断情報がメモリに保存されず、失われることがある。また、酸素センサー等の関連する部品の故障を同時に検出した場合、それらの診断情報も失われて警告灯が点灯しないおそれがある。そのため、関連部品の故障により排気ガスの量が増加した場合に検出できず、保安基準に適合しないおそれがある。

What is to be done about it

全車両、DMEのプログラムを更新する。 なお、上記措置は以下のいずれかにより行う。 - 販売店に入庫し、診断機に接続することにより実施する。 - 準備が整い次第、対象車両へ遠隔配信にて配信し、使用者自身でインストールする。

The two passages above are quoted in Japanese because that is the language the ministry published them in. This site keeps the wording a register had when it was read, and does not translate a safety notice.

Source: Ministry of Land, Infrastructure, Transport and Tourism website (出典:国土交通省ウェブサイト), used under the Public Data License 1.0. This site gathered the record, grouped it by notification number and set it in English around the ministry's own words; the notice itself is unaltered. CarsMultiverse is not the ministry and not a safety authority. To act on this notice, use the ministry's own document.

The Japanese register on this site

BMW elsewhere in this register

BMW is named on 1 notices in the copy of MLIT’s register held here.

The same part: コンピュータ(エンジン)

41 notices in this register name コンピュータ(エンジン). A defect that keeps returning under one heading is worth reading as a group rather than one notice at a time.

Reading this against the source

This page is what MLIT published in the recall notices it publishes, kept as it was read. The authority publishes only its current wording; if a notice is rewritten, the earlier version disappears there and is kept here. The whole register is at /japan, and how the reading is done is set out in the method.

This register keeps an index of its own for every maker and every year it holds: Japanese recalls on a BMW: 409 in the register, and 380 Japanese vehicle recall notifications filed in 2025.

The badge is free to use. It links to this page and nowhere else, and it never shows advertising.

No register publishes what happens after the letter. Owners do: tell us, in two taps.
