Defender air escaping under acceleration

My 2013 110 Defender has an issue after going through a muddy field yesterday, hoping someone can help as I can’t see anything wrong underneath or in the engine bay.

when accelerating there is the sound of rushing air other side of the passenger footwell, and the yellow engine light comes on and stays on. It lost power on the drive back too.

Any clues? My local specialist is closed until the New Year so a bit stuck. I had an account on here previously fir a long while but can’t locate the login details!

Any help much appreciated!

Check all the various boost hoses are connected.

Split hose can make rushing air sounds.

Thanks, I’ll get back under with a light, nothing was obvious when I looked earlier.

Might only be obvious when under boost. Give all the hoses a good squeeze and check for cracks and make sure they are securely attached

Maybe you hit something when off road?
