BMW calls for a fire hazard 145. 000 Cars of the brands BMW and Mini with diesel engine to check the cooler of the exhaust gas recirculation in the workshop. All affected car owners should be contacted from next week, defective parts would then be exchanged in the workshop.

Central component of exhaust gas decontamination In the event of leaky heat exchangers, glycol, which is added to the cooling water as an anti-freeze agent, could enter the exhaust gas recirculation and ignite in the hot exhaust gases together with oil residues. The exhaust gas recirculation (EGR) is one of the central components for reducing nitrogen oxide emissions in diesel and gasoline engines. Exhaust gas mixed with the fresh gas lowers the combustion temperature and thus the formation of nitrogen oxides if necessary. In order to increase its efficiency through cooler exhaust gas, the EGR is now usually integrated into the engine’s cooling circuit via a heat exchanger.

The years 2016 or 2017 produced coolers should be checked for leaks and replaced if necessary. The current recall affects vehicles in Germany, Great Britain and other countries, the BMW in Munich announced.

The problem concerned 2018 Earlier years of construction The first recall campaign with the same cause in August 2018 affected the BMW Series 3, 4, 5, 6, 7, X3, X4, X5 and X6 with four-cylinder diesel engines, which are available between April 2015 to September 2016 were built, and with 6-cylinder diesel engines that were used between July 2012 and June 2015 were built. The problem was first noticed in South Korea, where BMW already has more than 100. 000 Had to recall cars for the same reason. There was an engine fire there.
