sorry, forgot to mention its a Quattro.

 

Do the test outlined in this PDF:http://www.forgemotorsport.com/media/valve_service(1).pdf

 

don't keep the donut on there for too long. also if ur calipers were stuck, u would smell the brake pads which is extremely noticable so i doubt that's it. u should pm one of the techs like auditech79, techbod or rbrtech. they should be able to help u

 

you upgraded the DV but you dont have a chip?

 

yeah, i was told it was no good, figured might as well go witha good one, i did feel a difference though when i put it on, must have been really bad or something.

 

my guesses are as follows...

you need a boost guage now!

you most likely have a MAD (really bad) boost leak

Sounds like your Diverter valve isn't working properly either...you prolly have the wrong spring in it....

Are your tires new?...can the one with the hole be patched?...Do not drive your car for more than a couple miles with the spare on! (you will hump (toast ur diffs) Quattro...lol

if the tires are new and the one tire can't be patched get a new one and call it a day...

if your tires are old, and the one can't be patched get a new set (not a pair, all 4)

after you resoleve your wheel dilema, get a freakin boost guage...they take an hour to install, mine cost 60$ and was worth every penny...

after your boost guage is installed you will most likely be surprised to see that your hg/psi are screwy....if so, perform a vaccum test and replace leaky components/adjust diverter valve....

gl!

 

i dohave a boost gauge, when it runs good ill peak at about 8-9 and when it runs crappy i peak atlike 5-6 and hold at about 2-4psi. i got my new tire last night so that part is done.
