[s-cars] Ignition Problem

[Evan Desjardins]

S-Folk,

I've been having a problem with my car starting as of late, and I
wanted to query the collective wisdom of The All Knowing List.  Here
are the symptoms:

Initially the car would crank and crank and crank and would not start.
 Plenty of power, turning over fine, just wouldn't fire.  Had it towed
to a local shop, they said it was the plugs and swapped them out.  Car
would then start, but not consistently and usually not without several
cranks.  I was able to drive it to a specialty Audi/VW performance
shop in the area that was able to get it to start pretty regularly,
and then suddenly exhibit the same symptoms.

Here are the codes that the VAG-COM is pulling from it:

65535 - Internal control module memory error - intermittent.

00513 - Engine speed sensor G28 - no signal.

Any help in getting this figured out would be greatly appreciated!!!

Thanks again.
