Has anyone on here replaced the EVAP purge valve? Not the solenoid in the back of the intake, but the purge valve on the top middle of the intake with plastic vacuum lines attached to it. I ask because I want to purchase just the valve, but it looks like it comes with the valve and the vacuum lines attached for our cars. Is there any reason I can't buy just the valve and use my existing lines? Is there a benefit to changing to new lines at the same time? I'm just trying to save a little money because its almost double the cost for the complete unit with lines.

Part number is 06H906517H on the valve itself (which shows obsolete), but according to GenuineAudi I need 06H133781CK which includes the hoses attached as one unit.
