Was: Help! Check engine light, MOw: VAG-COM

[tihol tiholov]

First: Second Ti in not just jumping at parts, though the individual
coils have been a frequent culprit.  The codes in this case and the car
trouble seem imtermittent, so "CEL on" shouldn't be too worrisome - it
means that trouble happened but not necessarily continues to exist. 
Only a tool can turn it off.  I've driven with CEL on after fixing a
vacuum leak for many thousands of kms without trouble (on a much lowlier
VW 2.0 ;o).

Second: Got a VAG-COM and appreciate hearing from someone, who has the
Bentley (CD) with the scanner repair procedures that can be used with
VAG-COM or similar tool.  Pondering getting such CD and wondering how
much information beyond common automotive sense does it give - in other
words, is it worth the $70?
Can e-mail personally it so desired, I'm a digest-er.
TIA, 
Tihol
