So, I talked to a service advisor at my local dealer and he doesn't know what i'm talking about when I told him I wanted afterblow enabled on my car. Is there a code or something I can give him?<p>Also which vents does it blow out of when it engages? Defroster? Vents? Last position the hvac was in?<p>Thanks.

Hmm, maybe that's why my napkin on the defroster vents didn't move. I always have it on dash vents with the a/c running.<p>So if the car is shut off with the a/c on afterblow will go after 50 mins if it is activated.<p>What if the a/c button is shut off just prior to turning the car off? No afterblow that way?

Have dealer check his TNN's for this issue. <p>As an aside, I am not sure what is to be gained by shutting off the A/C. Modern rotary compressors use less energy that what is used by driving with your window down, and the increased drag caused by the open window.

The last report I saw on it was that drag caused by an open window exceeds parasitic drag caused by the compressor above 60 KPH.<p>Basically, window down in town, window up on the highway.

Re: (rogersampson)

+1 apologies for the hijack firehawk, but it seems like you found another dealer that can enable your afterblow right? <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0"><p>one last comment <p><TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD><i>Quote, originally posted by <b>JimLill</b> »</i></TD></TR><TR><TD CLASS="quote"><br>Tech Note #13<br>The discussion often comes back to IAT, the intake air temperature at the manifold.<p>I ran some simulations on an R-based model.....<p>each 1 deg Celsius increase in IAT results in peak HP being 1 HP less just based upon combustion factors alone.<p>If were able to keep the Intercooler at its peak efficiency, each 5 degC rise in ambient results in a 3 degC rise in IAT.<p>When the ECM senses high IAT it may take other protective measures that would further reduce HP.</TD></TR></TABLE><p>from <A HREF="http://forums.swedespeed.com/zerothread?id=94482&page=3" TARGET="_blank">http://forums.swedespeed.com/z...age=3</A><p><br>EDIT <br>to the OP: look here <A HREF="http://forums.swedespeed.com/zerothread?id=105524" TARGET="_blank">http://forums.swedespeed.com/zerothread?id=105524</A><br>there are some afterblow P/N's there, but I think they change year by year (or the info maybe outdated)<p>Like JRL said, another dealer is the best code<br><BR><BR>
