Hi,

I am sure that this may or may not have been covered. I was unsure about the source of this tip, but I recall reading it somewhere.

I read that more than half of the time the ABS sensors become a little loose or dislodged and require a gentle tapping to get them back into place, which usually make the ABS light on the dash go out.

Does anyone have experience with this type of repair?

 

I usually pull them out, clean, and tap them back in. Well, I DID do that back when I cared about ABS. Now my modulator and dash light are removed and I don't care.

 

I have never had the ABS lite on steady but the ABS used to come on whenever it wanted mostly making turns and it sucks truck will not stop, I finally removed the fuse under the hood I may try to fix at a later date and reinstall the screw in fuse

 

Mine was on all the time, grommets in the master cylinder reservoir were rotted out. I never even noticed till I found a puddle under the master one day leaving work. New grommets, bleed brakes, no light.

 

Where'd you find the grommets at? It took some serious Sherlock Holmes sh*t on my part to get part numbers for the Audi part #'s for the grommets that are the same Rover uses.

 

I went through the same thing, if I remember right I found them on ebay from a Audi parts supplier.

 

Would it be these parts below from a 1992 Audi 100 A6/V6?

This is from a thread at Discoweb and an Audi forum


This grommet is closest to the Discovery front of vehicle

Audi OEM part number: 4A0-611-817-A / 4A0611817A




This grommet is closest to the Discovery firewall

Audi OEM part number: 893-611-817-B / 893611817B

 

Hey that's my Dweb thread!
I thought maybe you had found them at AutoZone or something, haha.

 

I just realized that! Thank you for the hard work and the info

 

Question for the above scenario.

Could the "rotted" grommets allow air into the system, or create air pockets with the leaking which would lead to ABS issues?
