Voluntary Technical action for BMW Diesel: EGR“callback”

BMW responded with a voluntary Technical action on the fire hazards in some Diesel engines. The first, in South Korea appeared not a Problem that is now also an official recall but there are. Due to a malfunction in the exhaust gas recirculation may assume, under the circumstances, the danger of fire from the EGR module. In the context of Technical action, the AGR is being checked by the module and, where appropriate, replaced.

Different than I first thought only the 5 series is not affected by the action, also the owner of numerous other BMW models with N47, N57 or B47 engine will soon have to reckon with a covering Letter to your workshop. BMW calls 3P, 4P, 5 series, 6 series, 7 series, X3, X4, X5, and X6, wherein models with four-cylinder diesel engine from the period April 2015 until September 2016, as well as the same series with six-cylinder diesel engine from the production period July 2012 to June 2015, potentially are affected. In the case of vehicles of the 1 series and 2-series and the X1 with N47 or B47 engine no comparable problems are known so far, therefore, they are not affected by the Technical action.

Apparently, The six-cylinder Diesel N57 affected:

The official Statement from BMW in the wording:

Investigations of the BMW Group have shown that, similar to the current Situation in Korea – a malfunction of the exhaust gas recirculation module (EGR module), in rare cases, fires of BMW diesel vehicles in the European market.
The BMW Group has therefore decided, for this purpose, a Technical action to perform. The AGR is being checked by the module and in case of an error, the corresponding components of the potentially affected vehicles to be replaced.
The technical action includes the EGR module on the European market authorised BMW diesel models in the 3-, 4-, 5-, 6-series, 7-series, X3 – X4, X5 – X6 models with 4-cylinder diesel engines from the production period from April 2015 to September 2016, respectively, 6-cylinder diesel engines from the production period July 2012 to June 2015.
It is checked in Essence, the EGR cooler is the main part of the EGR module. In some cases, small amounts of the glycol can leak coolant in the EGR module to accumulate. In combination with the further accumulations of soot and Oil, this mixture of debris may be flammable and at high exhaust gas temperatures in EGR module ignite. In rare cases, it is Melted in the intake manifold, which can in extreme cases lead to a fire.
The decision for the technical campaign was made in accordance with the EU-wide regulations on the risk assessment. The customers of the affected vehicles will be contacted as soon as possible.
