It's same job to get at.
Remember I'm changing mine complete, so it's easy to split if you're prepared to remove the entire unit which will later require bleeding.

BBA-reman.com have got them instock for worldwide. I've paid £375+Tax+shipping.

If you have this problem of intermittent ABS warning lights and sensors are OK and Vag-Com tells you it's the "connection to Instrument cluster" you need a new ABS unit.

They are available here (remanufactured) less than half the price of a new one.<ul><li><a href="http://www.bba-reman.com/index.htm">http://www.bba-reman.com/index.htm</a</li></ul>

 

That is a great link.

I found it as well via the similar VW thread link posted earlier by ga_mueller.

I've written Audi customer care and will see if that leads anywhere. This problem seems to be far too common to be coincidence. If all else fails perhaps ordering a unit through BBA-reman.com for US shipment will be the way to go.

 

"Remanufactured" ABS arrived from BBA-reman this morning, final price with Tax + shipping was £460 rather expensive. Bad news, what a poor quality "thing" it was. For that price I thought I was getting something very professional. It has been ALL OVER SPRAYED with GREY PAINT, looks awful and was not filled with any fluid.
Not only that but the lower, partly hidden electrical cover was MISSING! electronics completely open to the atmosphere.
Needless to say,I sent it back.
However I took the chance to take off the electronic module (easy) and examined the exposed electronics. Have seen a photo on another posting.
The main cover is difficult to remove. I could see that this is where the repair has taken place. BBA have cut around the edge of the cover to remove it and then (roughly) glued it back on again, I could not disturb this for fear of them not accepting it back (there was also a seal on it" void if broken").
BBA are sending another pump unit out, they have already picked up the first one (shipping includes return pick-up)
Plan now is to fit only the module, a) because my hydraulics are OK b)the whole thing in grey looks terrible - I will either clean up the module or repaint it satin black. c)I believe it's much easier than trying to bleed the whole system (inc. pump/valves/etc.) and I will have to remove the front wheel/liner/washer bottle to get at it. I will send my old module back on the BBA hydraulics part. NB there's a £70.00 surchrge if not returned in 3 days.
I hope to open up my original module before returning it to examine further.I still believe it's just a bad connection/dry joint on the PCB.

I'm having the same problems. My ABS/BRAKE lights come on and off intermittently for no apparent reason. Pulled the codes myself, been to dealer etc. Everything points to the same thing. I need a new ABS controller for $1300.00. I phoned Audi to see if they could offer any assistance and was told "car is too old and has too many miles for consideration".

I didn't think 52000 miles was "too high" and it's a 2000 so it's just barely out of warranty.

I filed a complaint with the NTSB and recommend that anyone with this problem do the same.

I am about to take the electronics off of the side of the pump to see if there is anything obvious to the eye that can be fixed such as cold solder joints bad traces etc. I know others have physically removed the ABS units, but I would like to do this without compromising the hydraulics. Can anyone tell me if the electronics can be removed from the pump/modulator unit without interfering with the normal functionality of the braking system?????

 

Welcome aboard!
This is a widespread problem and needs addressing.
In answer to your question it is very easy to split off the electronics module once you can physically get at it. The hard part is getting the covers off, they are bonded on and break easily. However it looks easy to make a simple replacement cover (silicon it on!) from a flat piece of metal.
So far I've seen that the relays etc are pushed simply into the pcb and just lightly crimped together.
Hope someone finds the solution soon, it will make a lot of people very happy and save them a lot of expense and grief!
Trouble is that some (BBA) have found the secret and are making big bucks from it!!!!!!!

 

Now someone (who should know) thinks the problem is in the hydraulics.

it loses communication with the
instrument cluster due to a bad solenoid inside the hydraulic unit
98 and 99 specially the number of failures are very high

good luck

If Master technician thinks it's a soleniod problem, then it is still a fault with this module not the hydraulic part????? Hence the need to open up the other cover behind the solenoids.
