BMW X5 Recall 21V907: Diesel EGR Cooler Leak Can Melt Intake Manifold and Cause Fire

NHTSA campaign 21V907, reported November 19, 2021, 50,404 vehicles potentially affected.

What this recall means for you

The exhaust gas recirculation (EGR) cooler in these diesel vehicles may leak coolant internally. The coolant can mix with engine soot, potentially creating smoldering particles that can melt the intake manifold.

A melting intake manifold increases the risk of a fire. Owners should not wait to act on this issue.

An authorized BMW dealer will replace the EGR cooler and inspect the intake manifold, replacing it if necessary, at no cost to you. This recall includes vehicles previously recalled under 18V-755, which will need the new remedy performed. The remedy was expected to be available in June 2022. To check whether your vehicle has open recalls, enter your VIN on NHTSA's website, or contact BMW customer service at 1-800-525-7417.
