DIY Question Eng Cover Coil & O2 Sens
 

I work with a wrench in my hand all day, and have done plenty of DIY before on my cars.

Now I have an A3 2006 2.0T and I am not in Kansas anymore Toto....

So, I have purchased Genuine Audi Parts from the Dealership.

O2 Sensors (both), Fuel Filter, and Coil Packs. I open the hood, grab the front of the Engine cover, pull up and get to the point where I feel like I was forcing it.

So here are my questions (And yes I have searched the forums).

Specifically when possible, general when not:

1. Where are the contact points for the 2006 2.0T Engine Covers. And how do I remove it.

2. Top 3 things I should be cautious of when replacing the coil packs (Have some further reading from the threads to do at home on ideas of getting then in and out)

3. Where are the O2 Sensors located (best answer I got was near tail pipe and near the engine... :confused:)

4. Where is the Fuel Filter located, and is it as simple as R2 or am I dealing with pressure here and potentially could be inducing air into the system if I do it wrong.

5. Air filter, Spark Plugs ( done some reading on this ), Brake Fluid and Power Steering Fluid, are these safe to say this can be over the counter items?

Pictures and PDF files would be amazing.

Thanks in advance

A good place to find some answers is here http://oooo-a3.blogspot.com/ This guy has done some of the repairs you mention.

Cabin Filter is R2

Have the Coils and O2 Sensor going in tommorow as soon as I pick up my plugs and air filter that had to be shipped.

Today, went to change the fuel filter, and *^$% if the greedy %$%^ require a special tool to get those lines off, they are spring loaded, and to find a metric set is going to run about $60. Which I am refusing to pay.

Anyone have a work around?

2006 Audi A3 2.0T Oxygen Sensors Location :

FWD: Once you remove the engine cover, you will see the 4 Coil assemblies from left to right. Between the 2nd and 3rd top of coil, lean over the engine towards the fire wall and look down. Its staring right at ya, wire runs up the firewall and to the right.

REAR: put the car on a lift or a set of ramps. SET YOUR PARKING BREAK IF USING RAMPS! Between the passenger front and rear door, about 12" in you will see it sticking out of the muffler. The wire runs back towards the outside of the car, you will need a socket set to drop the plastic mud tray, about 6 or 8 "bolts". once you see where the plug ends, you will notice it sits in a holder, just bend it enough to get it out, no sense in pulling up your interior carpet to get to the screw head.

Time Required: 1 hour
Tools Needed: Flat Head Screw Driver, 7/8 Wrench, 3/8" Socket, 3" Extension, and I forgot what size socket for the bolts.

2006 Audi A3 2.0T Fuel Filter Location :

Put your car on a lift or on a set of car ramps, IF USING RAMPS SET YOUR PARKING BREAK!. On the passenger side, just in front of rear tire about 8" in.

Easy to get too, especially if you are already there changing out the O2 sensor, you do NOT have to remove the mud tray to do this job, but it probably makes it easier.

Time Required: 30 Mins
Tools Required: See Above if removing mud tray. And of course, not any old fuel line removal tool that you can find at an Auto Store will do, no no no, you have to go out and order one of these, check E-Bay, i may be selling mine :D.
