Not true...the puddle of fuel in the cylinder (see pic below using endoscope) and/or fuel soaked spark plugs (also below as well as other pics posted on this thread) will be their tell. BMW is up to revision 12 now, I removed 7's from my car and who needs 5 revisions unless they know something isn't right.
