hi guys..
i own an audi a4 2002 not quattro it's automatic and teptronic. it's 2.0.
first of all i live in lebanon and audi cars are new on our market..so there's not a lot of mechanicians that can fix it..they can only scan it for problems..
my car shakes while driving it ONLY between 1000 and 2000. when the car is parked everything is normal..whenever my rpm goes up tp 2000 the car stops of shaking..
i found lot of people having the same problem as me on the web..but no one said any solution for this problem..
i tried lots of things..btw the scanner shows that there's not any fault..i changed all the filters and the sparks and i even bought 1 coil and tried it in place of all 4 coils and when i putted it in one place i tested the car..so i tested it on all 4 places and nothing happened..
i need ur help guys..i like my car..and i want to fix this problem because i've tried all the mechanicians in my area and none of them was able to help me..

this is a video for a similar problem with another audi

 

So does it shake when you just rev it up or does it happen on acceleration?

If it happens when reving it up in neutral it could be bad engine or tranny mounts.
If it happens while accelerating it could be a bad front axle.

 

no it happens only when driving it..on neutral it doesnt shakes..
the shaking comes out on all spees 1st 2nd 3rd 4th .... but only when rpm is between 1000 and 2000...when accelerating it shakes but when the rpm goes up till 2000 the shaking stops ...

 

does a bad front axle shakes only when hitting the gaz pedal???
when the car is runing without hitting the gaz pedal there is no shaking..

 

If it is happening under acceleration more than likely the inner c/v joints are bad on the front axles.

 

what are the cv joints??? :S what does c/v means??

 

C/V joints are constant velocity joints. They are what transfers the power from the transmission too the front wheels. Most of the time the whole axle is replaced. It might be different where you are located.

 

Its probably just a vacuum leak

 

how can i be sure it's a vacuum leak??
and where is the vacuum located??

and m5s5 i checked the inner cv joints in a garage yesterday and it's still like new..the both cv joints are like new and they got no damage ...
