  Hi all,

   

  Just got 30 cm of fresh snow, so I _had_to_ take the Q for a spin,
  especially that I spent all Saturday afternoon till 9:00 PM just to
  repair the diff lock actuators...  The rear clevis pin was frozen to
  death and the Bowden cable was in need of some lubrication.  And the
  diff light switches don't work, the rear one is not there at all! 

  But I know for sure now that the diffs are locking.

   

  My question today is not related to diffs: after a long drive in the
  snow, (part throttle, not on boost often), I noticed the idle was kind
  of high (unintended acceleration again?) at 2500-3000 rpm.  I was doing
  less then 50 mph for about an hour. After a coupla WOT acceleration (can
  you imagine a Quattro behaving like a snowmobile), problem disappeared.

   

  Could it be that snow entered the intake track and prevented the
  throttle to close completely? How come this could be since there is an
  air filter, an intercooler, a turbo before the TB? 

   

  Did I forget to reinstall the air filter?
