RE: 2000 a4 avant fuel pump relay
The fuel pump relay wont help you test the evap purge valve. You need to activate the vavle using a vag-com to see if it is working. Then you can check wheter its sticking open or closed by blowing into the line. Also check to make sure the valve holds vacuum using a vacuum pump.
