Just want to add that it wouldn't be bad to kill your fuel supply, pull a fuse to the lift (rear) pump,you're still going to get shots of high pressure fuel because the high pressure pump is engine driven and will pump whatever is left in the line from the lift pump.No smoking.Come back with the values you pull for all 4 cylinders.

Ours is a 2012 also. Yes, can post the date a little later today.

That would be greatly appreciated. It seems some early 2012 Q5 engine manufactured have the same issued of the 2009-2011 engines. I have yet to find an engine manufactured before April 2012 that has the oil consumption or oldest chain tensioner. We just had our May 2012 engine check for chain tensioner at 50,000 miles and it was verified to be one of the revised parts. My thinking is they moved to a revised piston ring and chain tensioner around March/April 2012.

Check your tester on something easy to check like a lawn mower or snow blower to be sure its at least reading something.

Does this engine run? If so, you then have compression. If it doesn't run, then most likely tensioner failure.

" Is it possible to have no compression at all from the engine? " No that doesn't add up.You need to try a second compression gauge.At least have someone crank her over.while you hold a finger over each spark plug hole.You'll be able to tell if there's compression.
