EGR module with coolant, soot and oil deposits that can ignite (BMW 4- and 6-cylinder diesels, 2019 recall)

Engine / equipment

BMW 4- and 6-cylinder diesels, depending on model and engine (N47, B47, N57 and others)

Period mentioned

Recall of July 2019 (an extension of an earlier one)

Symptoms

The ADAC does not describe earlier symptoms. In the worst case the deposit ignites at high exhaust temperatures, the intake manifold melts and there can be a fire.

Possible cause described

According to the ADAC, small amounts of glycol can escape from the EGR cooler and collect in the module; with soot and oil traces they form a combustible mixture that can burn at high exhaust temperatures. In rare cases the intake manifold melts and, at the extreme, there is a fire. Depending on model and engine the EGR module is checked and defective parts replaced. It is free and covered 328,000 cars in Germany (with other models).

Check for the garage

Ask BMW by VIN whether your car is included and whether it was done. If you lose coolant with no visible leak or smell burning, stop the car and take it to a garage.
