Have the money now...looking at mods...

Much of what I read in the forum says a new DV is ideal for a chipped car. Others say new DV alone is appropriate for a failing OEM DV. I'm not ready just yet to chip my TT. I'm working off the warranty miles for now. And my OEM DV seems to have no problems right now. So, I'm wondering about the benefits of a new DV.

I've seen a few notes that more recent vintage TTs may have DVs that would show no benefit from change to Forge or other? Is that right? If so, what's the vintage break point and how to tell? My TT was built near the end of 2002 production (last 2002 Aviator Gray off boat in Long Beach).

I don't want to spend the money for a new DV if there's not a good benefit. I'll move on to the next mod.

Thanks for your ideas. (Amazing how many times folks continue to ask about DVs...)

The Mystro S4

I have had 3 D.V's go bad in my last 01 A4. I took no chances with my 02 TTqR.I replaced it at 800miles in the TT. There wasnt anything wrong with the stock DV but I knew it was going to fail. I have heard the stock DV's are improved but they still are the weakest link in the 1.8T motor. I replaced it with a Hyperboost DV. It didnt cost that much but it was worth the piece of mind. I only had 3000 miles on the A4 and the dealer replaced the D.V 3 times!
Go get a Hyperboost or Forge D.V now and save your self alot of dealer time and headaches.

I'm a "don't break it if it's not broken" type, so I'd change only for performance improvement

if you're EVER thinking about chipping your car, you'll want an aftermarket DV anyways. $150 should be no object for a TT owner, as these are pretty high-dollar cars. It's an OEM part that regardless version ("n" included, which I had before I replaced my dv last week Friday) are noted to fail at some point. Just the nature of the beast.

Changing to a piston type (Bailey, Forge, Hyperboost) replacement will feature a lifetime of reliable, dependable performance. Will you experience a performance difference even if your OEM dv doesn't have any of the symptoms of a failed dv? Quite possibly, YES. You see, just because a dv isn't honking or whistling doesn't mean it's performing at 100%.

I had the latest greatest OEM "N" version in my car, and replaced w/ a Bailey last week Friday like I said (I chipped on Thursday, so it was DEFINATELY time)... After chaning the DV I noticed improved throttle response, smoother shifting, decreased boost lag, and a nice (cosmetic) blow-off type "pfffft" sound when shifting or letting off the gas (more subtle than an actual blow off valve).

So replace it or don't replace it. This is a well-document subject and the info is out there - you should have all you need to make an educated decision!

no prob ;-)

Now maybe a 225 is a totally different animal and I'm all wrong but.....I've listened to folks here buy 3 or 4 different brands. Each one better than the last. Then there were mods to the aftermarket dv's then cooling fins. Then aftermarket DV's were needing replacement pistons and grease and even then some needed to be replaced as they failed to perform properly. I think many are taking the bait of the advertisers hook, line and sinker. APR recommends the Bosch for Stage 3 kits. MTM uses a Bosch. Why pay for a part you may not really need except to dress up your engine compartment?

If it really does fail change it but replacing parts for speculative future failures IMHO is not such great advice especially when some here have even split their hoses making the change.
