My light came on twice in 2 months of driving, goes right off after a restart.
I think thats not the problem that I am concerned about
My light does not come on when it pulsates.

When you say that it pulsates, are you talking about constant or periodic ulsating or just that one time when you start up in the AM and roll a few feet and then that's it?

I drove it to the resturant tonight , had not driven it in 2 days
when i backed out of the garage it pulsated twice while backing down the driveway
That was it it worked perfectly all the way down and back
no pulsating ,not lights,
no nothing
thats the way it acts.

Can someone give me an idea where the ABS sensors are.... I can't seem to find them on my handy dandy shop manual.

1989 300e

Thanks

found the info in another section of my manual....

where are they?
 

Lee, I have an 87 300e but no shop manual. Could you please advise where the front speed sensors are located & how to get to them. thanks

speed sensors
 

two bolts into the front calipers... snakes back up to and RCA connector.. I believe there are one or two plastic ties that keep them wrapped with the "brake pad worn" sensor and something else.

I have two spares and am going to replace the right side one tonight and see if that solves the problem... if not I will replace the left... if not...I guess I will have to buy a rear one....

Had two good speed sensors..so I know at least what direction to go on..
