my car has a E53 code with a slightly rough idle but only when your sitting at at light or in park when driving it is not noticeable, i cleaned the connectors that go to the ignition coil and did a quick inspection of the coil cleaned the battery connection at the battery another interesting note is the car runs smooth when you first start it up but when it gets to operating temperure and you turn the car off and then start it that's when the idle is rough i have a general knowledge with car repair i did see the ignition coil which seems simple to change should i start with that, thanks
