ECM Bad?

[Mark Hahn]

  Looking for advice on a rebuild/repair company for a '95 Audi 90S ECM.
The fault code was 1111 which is ECM and 2113 which is Camshaft sensor.  It
is on my girlfriends car and occaisionally the car will not start after
driving until it sits for awhile but cranks normally.  I can't find any
loose connections but I know some Porsche guys that say they have seen and
experienced some bad soldering joints on their ECM's which are obviously
different but are Bosch products.  Any advice will be appreciated.  Thanks,
MGH
