Code reading

[Ed Kellock]

A friend was kind enough to stop by this afternoon with his vag-com setup to
reset my airbag.  We struck out with that, I think because we may not have
followed the proper procedure.
 
We communicated with the Motronic and found 0533 Idle speed regulation 09-10
Adaption limit surpassed, Intermittent.  Huh?
 
We also got 00513 Engine speed sensor G28 03-00 No signal.  Is that just
because the engine wasn't running?
 
After he left when I discovered that we may not have followed proper
procedure according to Bentley to talk to the airbag, I decided to try to do
so with my El Cheapo code reader.  It would not power up with the trigger
module disconnected, so I reconnected it and voila, recorded 3 codes and
then cleared them.  They were: 01025, 00588, and 00532.  El Cheapo gives no
further info on these.  I do know that my airbag light came on some time ago
when I disconnected a connector either on the steering column or behind the
driver's knee bar, so I'm not overly concerned with what they codes mean,
but I would like to try to find out.
 
I'm curious about the idle speed regulation thing though.  Sounds like it
might point to the ISV.  
 
My Check Engine light is functional and it was not illuminated by these
Motronic error codes.
