Typically these things happen because the throttle body is dirty and the computer is searching for the propper setting with the idle speed control motor. May also be a vacuum leak .Check all of your small vac. hoses and clean throttle body and that should fix ya. Good Luick.

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?

Audi a4 shaking on rpm between 1000 and 2000


You have no mentioned any testing being done, the engine control module needs to be tested for fault codes, this should be a passive test (KOEO) and an engine running test (KOER). This is called a OBD2 fault code test KOEO test and KOER test.

I had the same issue with my '05 A4 1.8T.  Turns out it was the RPM sensor.  Audi tried to tell me it was teh fuel pump and the cam-shaft positioning sensor.  Paid for teh fuel pump replacement and it died 6 blocks from the dealership.  Then they replaced the RPM snesor, works great now... Except it's still an Audi.

I don't have steady rpm between 1000 and 2000 rpm


Pros
  • The EGR valve is vital to your car's emission controls.
Cons
  • When the EGR valve goes bad, it must be replaced.
Description
  • EGR Valve = Exhaust Gas Recirculation Valve.
  • The EGR valve controls formation of noxious emissions.
  • Rough idle and poor acceleration can be caused by a faulty EGR valve.
