hey guys......

I know theres tons of threads containing dv...bpv...bov questions and comments....and Ive looked at nearly all of them....but

I just wanted to clear something up....

The 710N dv valve on ecs tuning is a oem replacement for the dv that comes stock right?
The reason I ask is becuase I have been told that these are stock for 2000 and above so when I chip I should be fine and not in need to buy a 710N b/c that is what I have....

Please correct me if I am misinformed....thanks guys as always

I think you'll find that the 710N is not stock on the A4. I believe it is stock on the TT. The A4 DV part number ends with 710, but not 710N. I have a 2001 A4 and just replaced the DV myself. The one I took off was a plain 710, not a 710N. Hope this helps.

 

Oh ok...but then whats the difference between the 710 and the 710N and is it necessary if I wanna chip?

thanks

Well actually, I'm pretty sure that the 710N does come stock on A4's after a certain model year. Not sure which year that is though..I think the 710N is stock on all B6/8E's.

Main difference:
710 rated for roughly 8psi
710N rated for roughly 18psi

If you get a chip you must upgrade your DV to a 710N or better DV if you don't already have a 710N. The 710 may work for a little while but it will fail..probably within a month or so.

well i dont think i can say anything, its all been said.

 

Thanks T.....

thats very clear....

last question though I have a late B5...2000 a4 1.8tq tip sports pack all the trimmings....how do I know if I have the 710N or not...

Basically I dont want to order and install if I dont need to

thanks again bro.......

As far as I know, the only way to check easily is to get under the car with a flashlight and compare numbers. It might be hard to see, but the number is stamped on the side of the DV

 

What exactly happens when a DV fails, another words how do i know its failing?

 

You would notice a substantial loss in power and a weird honking noise with a large release of pressure from your engine....
