Abs module replacement question

Just got back from the dealership due to abs asc lights coming on. The test showed that a rear speed sensor was bad and also the abs module was bad. My question is this...i asked the service tech if the car was still driveable till i got the money ($1500.00) freed up. He said sometimes there can be a "progressive fault" and that it could cause a problem of an "idle only" condition and i couldnt accelerate at all?

I also asked if there was a possibility of putting in a used module. He said that the modules have to be new, that the module has to be programmed to the vin number of the car, and cant be reprogrammed. Essentially saying one module cant be interchanged ,even if it is the same model ,year etc ? Then wanted me to prepay to order the parts. I told him i wanted to hold off till i checked out a few "options". I would prefer to drive the car till i get the cash together but obviously wouldnt want to be stranded. Any thoughts would be appreciated?

I was on eBay when I read your post. Thought you might find this helpful. http://cgi.ebay.com/ebaymotors/BMW-B...Q5fAccessories It seems like the speed sensor error might be a symptom of the Module, so fixing the module may keep you from having to buy a new sensor. Maybe you can email/Call the repair place and get a better sense of their process and to see if it is for you.

I got spares of all the modules if you want to try used ones.

As usual you guys are extremely helpful. I ordered a used module with the correct oem to switch out. Hopefully this will work. My experience with my local dealership isnt that confident regarding accurate troubleshooting and $1500 is not chump change .

I'll keep you posted .

Thanks

Won't you have to have it coded to your car? The benefit of a rebuild is not having to get the dealer involved with the coding

The VIN needs recoding if you purchase new or used module. I had a Z3 Coupe with ASC/ABS problem for couple of years. Finally fixed with rebuild module. Module Master offer 5 years warranty when new OEM is 3 years I believe.

I contacted modulemaster and was told that 97 and earlier model years cant be rebuilt. Lucky me, mine is a 97. I bought a used unit and will see if this will work.
I do have a question regarding changing it out. I will have to disconnect the hydraulic lines to remove the module as it is a one piece unit. With the abs asc+t system would it be adviseable to have the dealer change it out. (my bently manual says to take it to the dealer)

Mine is a 99 so I can't talk real good for a 97. But removing my module did not require disconnecting anything beyond the wiring harness and removing four screws. If I had to crack the hydraulic lines, I would've taken it to my independent mechanic.

My write-up FWIW.

Mein Auto: 98 Z3
I know this is an old thread, but I'm looking into a used module as module master can't repair one from prior to 99 and I have a 98Z3. Has anyone tried putting in a used ABS/ASC module and have any success with it?
