Alternate Method - Accessing the exhaust valve through the wheel housing.

An easier way to access the exhaust valve is through the right rear wheel housing.

The housing is in two pieces, the rear section must be removed first. Tool required are T25 and T30 Torx drivers and a 10mm socket wrench. Some of the T30 Torx screws attach the bottom of the housing to the undertrays, so if you encounter any difficulty in removing the housing liners look closely to see if you've missed any screws.

Once the housing is removed, the exhaust valve is easy to locate.

If you have any difficulty in unhooking the electrical connector, you can temporarily remove the entire valve from the frame member to get a better look at it.
