99% of the time, it's either a burnt out glow plug or built up  
oxidization on the glow plug harness/glow plugs.  TDI Club had an  
excellent writeup on the glow plug system:


Mine CEL would come on about every 6 months.  I'd clean the harness,  
put it back on, reset the CEL, and all would be good for awhile.   
Since the last time, however, I really had a glow plug issue, so I  
replaced all 4.  The light hasn't come back.

I can't help much on the ABS problem, since I've never had a problem.   
Good luck with that one.

On another note, I was out doing struts today.  I got the rears  
replaced, but when it came to the fronts, they require a special tool  
to spread the strut clamp that I didn't bother to order (!).  So I got  
to button it up and call it a day.  I bought Bilstein TCs, and on my  
maiden voyage with the new rear suspension, I found that the back end  
is tight now.  No more bouncy bouncy.  Highly recommended :-D
