[s-cars] Check system

Bob,

Have you checked the bulbs for the check system?  There should be two 
bulbs back there, one with a red condom, one with a yellow.  From what I 
recall, with these blown, you will see nothing at the auto check system 
display.  Also, IIRC, swapping the condoms between bulbs was not an 
option on mine, and I got fresh bulbs from the dealer, proper red and 
yellow colors.  Family pictures reveal 4A0 919 040A as 1.5watt red, and 
4A0 919 040B as 1.5watt yellow bulbs.

For down and dirty testing, putting any working bulb in place of the bad 
red/yellow ones will validate a bad bulb/good autocheck display.  
Remember if you place the good bulb in place of the red colored one, 
check it with the running lights on, and vice versa with the lights off 
for the yellow bulb.

HTH,
Stott
