Mercedes-Benz CEL On P2187 P2189 P2004 P2005 P2006

The check engine light may turn on in 2005-2015 Mercedes-Benz vehicles equipped with V6 M272 and V8 M273 engines due to the swirl flap system's failure.

We see quite frequently that the tumble flap gets stuck activated position triggering fault codes such as P2004, P2005, and P2006.

Solution

Mercedes-Benz dealership's recommended solution may be to replace the entire intake manifold, which does fix the problem but can be very expensive.

Instead of replacing the intake manifold, we recommend replacing the broken lever. You can purchase an M272 Air Flap Runner Repair Kit and have your auto mechanic replace the broken pieces.
