[s-cars] Flywheel TDC mark

[Jeremiah Curry]

That may be true.  I was using three references when doing my timing belt. 
Fred's guide http://12v.org/urs/FredMsTimingBeltR&RDIY.pdf where he could 
not find a mark, SJM which shows a mark like I saw: 
http://www.sjmautotechnik.com/trouble_shooting/S4timing.htm and the S2 site, 
that shows an image like what I saw aligned where I saw it (pg 5-6):

good news is it worked for me ;)

That faint mark may give some a warm and fuzzy feeling after matching with 
the other clues for TDC, but it shouldn’t, and it won’t for any old school 
mechanic who has timed older Audis.  That mark has always been made with a 
die and hammer with the #1 cylinder precisely at TDC.  No trained German 
mechanic with a job assembling Audi engines is going to place that oval
mark anywhere but the center of the observation port.  Since it is a die 
struck mark, it can not be confused with a spurious scratch or an awl 
scratch made by a DIY mech.
