I have an 05 coupe, and even with the VDC off I'll still get the slip light in extreme cases - like in the autocross. I think it really just depends on the situation.

 

i have an 03 sedan btw

 

clunking from the front of the car on the G35s is usually associated with the compression rods (the curved lower suspension arms at the bottom of the front suspension).
This could be a pretty good culprit, we replace these fairly often here.

clunking noises from these arms occur randomly but usually the noise is heard under heavy cornering, and bumps etc.. basically any situation where the suspension is under excessive stress, ie launching the car and what not.

we have these plenty in stock as well, pm me if you'd like prices

 

Exactly what the manual says. The manaul clearly states that the ABLS will STILL work even with the VDC off, and the slip light may blink.

Obviously, you slammed on the brakes, triggered ABS and activated(?) ABLS.

 

Both the manual and hyukki are absolutly correct. just because the vdc is off doesnt mean you dont have all traction systems off.

 

i think i'd rather have the ablsd working than no traction aids of any kind, i also have an '03 sedan, and since i got the rear links replaced i can't drive with the vdc on anymore, the car is just so controllable, but ablsd is a godsend for getting moving in snow, peg legs are just not as much fun...

though i have to admit i'ven't noticed any clunking while sliding mildly. i did, however, set it into a spin in an empty parking lot to see how it would handle. Even with the vdc off it corrected once i made it go into a severe wipe-out type situation, and it clunked as the brakes kicked in, but was somewhat hard to tell, since you're also getting kicked by the brakes suddenly having traction. if you're in an "uncontrolled" slide/spin, you'll probably notice the clunk, normal sliding / drifting, less likely.

 

Actually reading the manaul ftw.
