Register
Japan — Ministry of Land, Infrastructure, Transport and Tourism

What the ministry says is wrong

制動倍力装置のバキュームラインに装着されているチェックバルブの材質が不適切なため、密閉不良が起こりバキュームポンプから霧化したエンジンオイルが制動倍力装置に浸入し、内部ダイヤフラムが損傷することがある。そのため、当該倍力装置の気密性が保持できなくなり、最悪の場合、制動停止距離が長くなるおそれがある。

What is to be done about it

全車両、バキュームラインを対策品と交換する。また、制動倍力装置へのエンジンオイル浸入の有無を点検し、エンジンオイルの浸入があった場合は、バキュームポンプ、制動倍力装置及びブレーキマスターシリンダーを新品と交換する。

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: 圧力制御伝達部

409 notices in this register name 圧力制御伝達部. 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 372 Japanese vehicle recall notifications filed in 2010.
