hi

thank you

Sounds like teh Dr. left his forceps IN the patient! Soes it hurt what you cough, too?

Take IT BACK, RIGHT AWAY! It AIN'T supposed to rattle. Either something was left undone, or, something was improperly positioned.

TAKE IT BACK!!! MAKE 'em FIX IT!!!

 

hello again
the sound is really low now.u can barely hear it.i took it to them this morning and they think its the ac compressor.even though i get it even when ac is off.the sound is really low now..what could this be?

 

sometimes this sound just disappears completely even in cold start.but sometimes it comes back again ...even when the engines warm.please help..my mechanic wasnt any help in this..im sure this is not very serious but i dont like my car to sound like a diesel...

thank you

 

do this:

Rummage around in the closet and find an old roll of christmas wrapping paper
Ditch teh paper but KEEP the cardboard roll
stick one end of the roll up to your ear
point the other at various places around where you hear teh noise, when teh noise is presenting

This should help you pin-point exactly where the noise is coming from and/or what is causing it. Enlist the aid of someone with more experience working around motore (other than the mechanic who did the original repairs), if you hafta. Have THEM listen to the noise through your ILD ((I)mprovised (L)istening (D)evice)

 

I am living a similar story with a different engine. It is a 2003 A4 with the 3.0 engine. At an idle it makes a knocking sound similar to a diesel. Where did you get your parts?
