[s-cars] New faltering problem

[Robert Myers]

Tom,

The CEL did not come on.  I am unable easily to check for stored codes 
since VAG-COM is unavailable due to the laptop with it installed being in 
the shop for repairs.  Checking for codes will remain until I get my laptop 
back.  (BTW, anybody wanna buy a used Dell laptop - CHEAP?  I'm about to 
drop-kick it into the next county. :-( )  The new OXS will be tested in the 
AM after a full night of cooling.
