BMW’s high-profile diesel car ‘technical campaign’ has been expanded to 1.6 million cars globally, following further internal investigations.
The initial recall of 480,000 vehicles was announced in August 2018, for European and Asian countries. It has been extended to “engines with a similar technical setup”.
The issue is related to coolant leakage from the exhaust gas recirculation (EGR) cooler. When mixed with diesel engine soot deposits and subjected to the high temperatures such systems run at, BMW says it can result in “smouldering particles”.
This can melt the intake manifold and “in extremely rare cases result in fire”. Both 2.0-litre four-cylinder and 3.0-litre six-cylinder cars are affected.
There have been numerous reports of BMW diesel cars catching fire in the news over recent months. In August, BMW’s South Korea division apologised for the fire incidents during a press conference.
BMW’s latest statement says the latest internal investigations “posed no significant risk to our customers… Nonetheless, the BMW Group decided to further reduce even this minor risk by expanding the country-specific technical campaigns”.
The firm says owners of vehicles involved in the technical campaign recall will be contacted directly. Cars built between August 2010 and August 2017 may be subject to recall.
As part of the recall, EGR modules will be checked and, if necessary, any faulty components replaced free of charge.
