Hi all <br>I haven't posted much on the site but i am a avid watcher of the site .<br>I was just wondering if any one had ever up graded there AWD Haldex controller , I've found this on <br>a VW site and wondered if it would fit on an R ?<p> <A HREF="http://www.vagtech.co.uk/index.php?option=com_content&view=article&id=59&Itemid=59" TARGET="_blank">http://www.vagtech.co.uk/index...id=59</A><p>Tim <p>(If this link doesn't work then you'll have to copy and paste it )
AWD Upgrade

Re: AWD Upgrade (tim1981)
There was a company (Heico I think) that had worked on an upgraded "flash" for the Haldex, but Volvo shut that little operation down (as it was a collaboration, not an independent project). It can be done, but would take someone with a lot of knowledge of the system. Also, the angle gear on our cars would probably not enjoy a more aggressive rear drive scenario. An "on the fly" or switchable program would be nice, depending on road conditions, climate/region, and track use.

that website does have the control module that we need<br><IMG SRC="http://www.hpamotorsports.com/images/drive/gen2.jpg" BORDER="0">...only problem is NO ONE makes an upgraded bevel gear (or collar) so if you were to install the upgrade ...by by to about 1500 worth of parts...<br>hey i think thats a good idea for an IPD Performance part!
Re: (PSAC)
The driveshaft is always there (and therefore always engaged). It is then connected to the Haldex unit that is then disengaged, or "fully" engaged sucking up to 50% (I believe) of the hp/tque from the transmission. So while "always engaged," the angle gear has a marginal load. A modified programming in the Haldex module would have it engaged more often and for more power than stock. You see the issue...<p>I also wonder how that would all interact w/ the chassis and traction control gizmos.

Re: (AthruC)
My neighbor just upgraded the Haldex unit in his VW R32.<p>He asked me if there was a similar unit for the Volvo Rs. So I'm glad to see this discussed here. But my impression is the a Haldex upgrade could mean a downgrade to our reliability...something I don't want.<p>At any rae, I have my rear wheel drive coupe to give me more jollys when needed. The R is a very good daily driver and winter car for up here.

Re: AWD Upgrade (tim1981)
Almost EVERY component would have to be upgraded especially in an R.<p>This was SO urgent that Volvo let Haldex know that if they were going to try to sell this, that there would be "serious consequences"....the project was shut down<br>This unit has been around since 04 but Volvo was quite unmovable on this.

No one seems to have a spare good coupling, so this has never been looked into (reinforcing or machining a better one)

I'm pretty sure this hasn't been looked into. I know when mine failed I checked to see if a heavy duty part was available.
