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
