Video clip for troubleshooting/diagnosis purposes. This shows a cold engine start in the 3.2 inline 6 diesel engine. After starting the engine is reasonably steady and putting my hand on the air filter box doesn't have a big effect. After revving up a little, coming back to idle there is a booming sound. At this point, pressing on the air filter enclosure dampens the sound. Some days it starts out boomy, others it's only occasional. www.mbclub.co.uk
