Title: When type-C DVs go bad - epic fail!!
Post by: tony_danza on March 31, 2009, 10:28:05 am
Felt this go pop in the week, t'was p***ing boost like a good-un! Luckily I had a type-G in reserve for a quick swap-a-roo.

No fault codes/warning lights (although VCDS logging or a boost gauge would have obviously shown the drop), just the butt dyno and keen hearing in my diagnostic toolbox!

28K, 19k of which it has been mapped... its two and a half years young.

I don't see the point of the Forge one for a K03, unless you want a boost gauge.

Thats not to bad at all really is it, they do reckon the later revision is much better as well.  I have never had an issue with a later type DV on the mapped ED30 I had and on the mapped S3 I have now :happy2:  Although i did use the Forge 1 on my regular mapped GTI as a precauition as much as anything :smiley:

Is the G revision the new piston type valve??

My valves were blowing every 4-6k miles on my K03 GTI until I went Forge..

Yes Steve, even easier to find on yours I believe?

Dunno about the ins and outs of a Ver G Jonny, but if I got 2.5 years out of a C and at 1/5th of the price of a Forge - if the G is better, then I ain't upgrading!

x2 I kept blowing B and C revision gauges until I swapped for the forge unit. This G unit (haha) is meant to be very reliable though.

Should be printed on the DV in white lettering.

Mine's got the VW and Audi symbol and underneath it:

06F 145 710 C <---- C being the version.
5900 110 7044
7.00415.03      APG

Oooh nasty!!

I can understand your methodology around keeping with the OEM DV's, but it would just niggle me knowing there maybe a fault developing in the DV. (a bit like my ARB brackets :sick:)
