A problem with the exhaust gas recirculation (EGR) cooler may occur with the BMW Series 3, 4, 5, 6, 7, X3, X4, X5 and X6 with four-cylinder diesel engines manufactured from August 2010 to August 2017.
Let’s remember that at the beginning it was just a local recall in South Korea, where the local authorities registered more than 30 engine or whole vehicle fires only in 2018. In August 2018, BMW recognized that for the same reason it would be necessary to check around 324,000 diesel models also in Europe (we wrote here).
In October 2018, bmwblog.com reported that the recall is expanding worldwide and will cover 1.6 million vehicles. We wrote about it here. Now, according to autoservicepraxis.de, this recall has been expanded worldwide by another 232,000 vehicles.
The reason is still the possibility that glycol may escape from the exhaust gas recirculation cooler and the combination of soot particles and high temperatures in the EGR module may cause them to ignite. However, the possibility of this occurring is low, according to the manufacturer.
The date of production of the EGR cooler will be checked with the vehicles being recalled. The cooler should be replaced if necessary. Depending on the amount of work, it can take from half an hour (check only) to three hours (replacement).
