Check all vacuum lines and especially the one behind the throttle body to make sure none are off and also check the EGR valve and if it has not had a tune up in awhile check the coil pack over the spark plugs

Coils usually breakdown under load(accelleration). A sticky valve of lifter is easy to check with a vacuum guage hooked up to the manifold. It will show a steady needle at idle if ok but the needle will bounce if the valve sticks. Does not sound like a coil.

2009 Audi A4 startup shaking?


Could be spark plugs or a bad ignition coil (but the dealership should have checked the coils). I would replace the spark plugs and air filter (just to be safe) and see if the problem goes away. Both are pretty inexpensive and easy to do. Presumabely your dealership checked for fault codes in the engine and didn't find any?

Sounds strange,look in your manual this may be a warning code if it bounces to the same rpm range. if not check your ecu black box ,if water or damp getting inside it may be causing the problem untill the engine heat dryes it out.
