My 2014 has 106K miles and I started smelling diesel exhaust in the passenger compartment. Tear-down revealed that the exhaust flex pipe that connects the two ends of the EGR cooler had burned through - not replaceable separately. Coolers are back-ordered two months from European suppliers, none available in the US.
I talked to BMW North America - they are unwilling to give any info except to say that previous (including third party) repairs may be reimbursed upon dealer inspection. The official EGR cooler recall starts 17 Dec 2018.
The local BMW dealer was unhelpful and unfriendly, routing me to their Subaru service department presumably to get rid of me.
The US recall is for 40,000 cars, but globally the recall has expanded to 1.6 million vehicles.
Based on parts supply, I'm betting my F30 could be undriveable for many months. I bought a diesel Passat yesterday to fill those months.
