DV location
Newbe here and i am new to Audi. Can any body tell me where the DV is located on a 02 A4 1.8T. I have done some searches but cant realy find a thread on where it is. If any body has a diagram or something and what the difficulty is on this mod for a newbe. Any info would help.

Should be lots of info, even a sticky at the top. Ive never checked it, but it should have good info. Its easy, lift the car, take off the bottom plastic thing, should be 4-6 screws that take about half to a full turn. pull that down, get under the car, about where your headlight and grill are, draw a invisible line down and slide under right there. Look up should be a good sized black pipe right infront of your eyes coming from the turbo, from there you should be able to locate your dv, its on the top side of the black piping.

put your car on ramps/jacks (front)
remove belly pan
get under passenger side, DV is near radiator/cooling fans
1time OEM clamps are a bitch, use an L needle, if u cant break them, dremel them off
reinstall new DV, noting orientation of old one before you remove!!!

everyone suggests doing it from the bottom but i did it from the top. you just gotta find a friend with little hands lol. just look down in between the pulleys and the radiator, should be down about a foot and a little on the left. if you still can't find it, follow the blue vacuum hose coming out of the intake manifold. it goes right to the dv.
here's some DIY articles

RE: DV location
ok seems to me that those are b5 models...more for a b6 model here that will show us where it is? im getting the bov not the dv. i know chaos had helped me alot on this issues, its just like i really have no idea what it looks like, where it is or even what to do

RE: DV location
I just installed a Forge 007 in my car. For the B6's, you'll find it on the right side of the car, behind the radiator, close to the right headlight. Best way to get to the DV is from underneath, which means you'll have to take off the plastic skidplate that's underneath the engine. The stock hose clamps that are used on the stock DV are a PITA to get off. Once you figure out how to get them off, the rest of it is really easy. It took me about an hour to do the whole swap.
You're better off swapping your DV at the same time you do your next oil change. This way you only have to jack up your car once, and remove the skidplate once.

RE: DV location
In order to limit the boost pressure, a valve flap is opened by a pressure unit at the exhaust gas turbine. This can be used as required to allow some of the exhaust gases to bypass the exhaust gas turbine. This reduces the power output of the turbine and therefore also the delivery of the compressor.
The pressure unit on the turbocharger is actuated via a control line using tapped air from the compressor. The control pressure needs to be reduced in order to increase the boost pressure.
The pressure in the control line is reduced via boost pressure control solenoid valve -N75, which releases pressure from the control line and therefore reduces the control pressure (in order to minimise noise the air is directed into the large intake hose). Due to the low control pressure the exhaust gas valve flap remains closed for longer.
When there is no voltage on the valve, the full control pressure immediately becomes effective at the pressure unit and the boost pressure is governed down to a minimum value.
In order to lower the control pressure (with the aim of increasing the boost pressure) it is necessary for the solenoid valve to open further. This requires a current increase. This change in current is achieved by increasing the duty cycle.
