Question about 2004 Audi A4

2 Answers

2004 Audi A4 1.8 - jerks/jolts while accelerating from 0-20 mph

While accelerating from complete stop car vibrates/jerks for 1-2 seconds and then runs perfectly fine. It will happen again if I stop or slow down at a light and then try to pick up. Checked transmission fluid levels its good, also scanned for codes nothing shows up. No check engine lights as well. Any suggestions what can be the problem.

It sounds like there may be an issue with your ignition system.

Check the ignition wires, distributor cap, spark plugs.

My car wont start


Looks to me like dirt in the fuel pipes. A bad fuel pump or even air in the fuel pipes. If you recently came with an empty fuel tank, this could have caused dirt came in the rules system. Check if fuel is coming to the Carburettor / fuel injection

Pt cruiser jerks when acclerating, hesitates when not accelerating, fine when idle


I am not saying this is the solution or this is the problem but the PT cruiser suffer from code P0344 Which is the cam position sensor which causes misfire, the solution is a reflash of the ECM.But before a reflash the Camshaft postion sensor needs to be verified for working condition and if possible duplicated.Once the Check Engine light does come on you automatically go to limp home mode, This is the drag that you experience,the purpose is to protect the catalytic,in case there was a true condition with intermittent cam postion sensor,You need the check engine light code, then you can go from there.

Transmission Slight Jerking When Slowing & Accelerating


Have you changed the trasmission fluid and filter in your jeep lately, if not do so and that just might stop the jerking in your jeep, and if that does not do the trick you will need to have your trasmission checked out by a trasmission shop.
