I have a 2004 2.9Crdi SE auto. About 18 months ago the ABS light came on every time I did 70mph for more than a few minutes. The main dealer replaced the n/s/f sensor and speed sensor. Didn't work. Replaced ABS unit/pump. Didn't work. Eventually (they said) found hairline crack in ABS ring on drive shaft. Fitted new drive shaft which cured light problem but left me with the ABS cutting in too early (10-20mph). Another ABS unit fitted better but not quite right but light still out. Tested ABS on slippery surface. Worked fine. Strange that KIA no nothing about this cutting in early problem but several motoring magazines (inc Auto Express) do. Decided live with it because brakes work fine even when it occasionally cuts in early and I didn't want the dealer making it worse or bugger up my tracking again! . Guess what. Did 70mph last week. You've got it the ruddy ABS light came on again. At least when its on the ABS wont misbehave. Stopping and restarting puts the light out so should be ok for MOT test.Now warranty is out it can stay like it,but its bloody annoying. Anybody got any ideas.? Regards John.
