If you want a good selection id try a parts locator. One place that can find you a good short or long block for a [URL="http://www.texas-junkyards.com"]Audi A4 engine[/URL] is [url=http://www.texas-junkyards.com]TEXAS Junkyards[/url], Junk Yards in TEXAS TX salvage recycler. They have a link somehow to multiples of thousands of recycling centers and will locate the best one for you.

You may have a coil pack going bad. They're on the front top of the engine - you'll see them if you follow the spark plug wires back. Do you have any codes from having the engine scanned? If you can get it scanned (AutoZone will do it free), post the codes up and we'll see which cylinder(s) are misfiring. From there, you can swap coilpacks around and see whether the misfires follow the packs or stay in the original cylinders. If they move, you have a bad coil pack or two. If they don't, since you've already changed plugs and wires, I'd see about having the injectors diagnosed to see if any of them are failing.

SOURCE: location of fuel filter on a 2001 audi tt quattro

On a 2001 Audi TT Quattro the fuel filter is located forward of the fuel tank, in the right rear wheel well area. The fuel line clamps are a bit tricky. The change will improve performance. The owners manual does not even list changing the filter. But do it! use a Fram, and it fit perfectly. Good luck.

The insert or cartridge filters are easy to change..You must jack up the front of the car, remove the engine belly pan. in the front of the motor there is a black cylindrical housing for the oil filter cartridge..On the bottom is a cap that just screws off..Unscrew the cap, take it off, slide the old insert off, then slide the new one on..Screw the cap back on and voila! you are finished..If the insert came with a new rubber o-ring, make sure to replace the old one on the cap.
