AudiForums.com - A3 75K Service Info & DIY

75K Recommended Maintenance for your A3 Audi is Check Tires, Check Fluids, Lubricate Wipers and Change Oil.

But your not a typical A3 Owner now are you...

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

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

1. Fuel Filter
2. Plugs (Gapped to 32 but 30 will work)
3. Coil Packs
4. Front and Rear Oxygen Sensors

I have also picked up a new cabin filter and a K&N Air Filter (If you dont have one already)

So, I pop my hood, and take a look inside and ask myself:

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

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?

And here are my (And Your) answers:

Tons of good write up's here for all A3 Related Jobs, including the Coil and Plug job I did. His writeups are fantastic.

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.

A good Audi Mechanic will charge $50-$60, a Dealer will charge $190. :mad:

I had my oil changed and my brake system flushed and refilled at the local Jiffy Lube for lack of time and I simply ate lunch across the street while they did it on my lunch break.

Remember 5W30 Synthetic only.

Also remember that you should rotate your tires on Audi's at least every 5-8K to avoid wearing out your tires. There are many threads discussing this issue, Toe In/Camber, Parts made out of rubber that are typically metal, nature of the beast etc.. etc.. Mostly you will see your tires wearing excessively on the inner or outer edges, hear alot of tire noise etc. I would suggest having an Audi shop or your dealer do your allignments front and back. And unless you are driving it on the track, or have a habbit of breaking speed limits around corners, go for harder tires, they simply last longer. 17" can go up to H in that department if not more on some brands.

Good Luck and enjoy your A3!
