Hello new guy here i went to autozone and got the codes because my check engine just came on... the codes are p301 p303 p304 so i think ineed ignition coils or spark plugs and would you recommend doing both at the same time and how hard would this job be called the audi dealerand they said 4 hours of labor is that true? Or could i take it to an independent shop and have them do it is the job hard thanks.

P301, P303, and P304 aren't codes, are you sure there wasn't a 0 before it like P0301?
If yes then you need to replace the coils on cylinder 1,3, and 4.
What commonly happens on the 3.0L is someone breaks the coil packs when prying up on them to do the spark plugs, i would replace all of them cause another one is gonna fail down the road.
I gaurantee it.

 

there is a 0 in front thanks auditech...is this a difficult job to do meaning something that has to be done at the dealer or can i take it to a basic garage? any paticaular brand to get with the coil packs and where is a good place online to get them

 

I think you can get them at www.ecstuning.com for all 6 at a much better price, the dealer would charge you $300 per coil.
Its a very easy job to do yourself, they just push onto the spark plug. There are two small T15 torx bolts holding down the harness, take those out, dis-connect the connectors and pull the old coils out of there.

 

300 per coil sounds a lil high?

 

Thats dealer prices, you can probably get all 6 from ecs for $300

 

cool thanks alot audi tech
