Compression tests. 4.2 S4 Section 2003-2009

Any reason you did with engine cold? Typically you see these done with the engine warmed up. Just curious. Consistent results across the board though.

Mileage: 158,000

followed factory procedure as per Elsawin - engine oil above 30C (approx.), all plugs pulled, throttle pedal pushed while testing (not sure that matters but it’s in the directions, I also had the throttle plate manually held open). The engine was not warmed up to operating temp before the test but the temp outside was 30C so the engine oil should’ve been at about the proper temp.
