E39 new ABS unit, how much?
Discussion
My ABS and traction control light is on again, speedo is working. Yesterday I drove through some very heavy rain and hit a big puddle/lake on the A35 in Poole, and this morning it's on and won't switch off after numerous times of switching on and off. It isn't the ignition barrel playing up, as thats 6 weeks old. I reckon I might just replace the sensor and the ABS unit as this isn't the first time it's happened. Worth noting that I tested the brakes this morning on a safe bit of road, absolutely fine, but I don't want to run the car with that problem. Any idea on costs for these parts? It's going to an indie for any work it has done. It's a 1999 528i SE Auto.
Sparks,
I have just been through all of this with my e39. First thing i would say is definately get OEM/genuine wheels sensors if they are the problem. find ATE ones for £80ish. If the rain affects it chances are its the sensor.
If its the ABS module itself BBA-Reman can do them for £150ish depending on which bosch unit you have.

Hang on, you can't go changing the ABS ECU / pump without some proper diagnosis. Have you had the car plugged in? If you're anywhere near Bristol I can do it for you. It will almost certainly show that one of the sensors is borked (mine did the same after some puddle action). You definitely need to do that before getting into the expensive stuff.

You might well find removing them is a bit of a pig of a job. I had to drill mine out.
And if you do that you can drill into the reluctor on the back of the wheel bearing... Apparently 
Don't drill/poke anything any deeper than the fully round part of the sensor or you'll end up changing the bearing too....

OK once.
A diagnosis will probably bring up rear left speed sensor. Simple, get the ABS/speed sensor changed - however, this code also comes up when the ABS module is kaput. You can send the module off to BBA reman as said above. They will test the unit for £25 and return it to you if it's ok. Cheaper this way than getting the ABS sensor changed for £135(what I payed at an Indy) only to find it is your module after all.
The ABS modules are very expensive to buy new, but as already said BBA Reman recondition them for 150-200 quid with a two year warranty.
If it does turn out to be your sensor I would strongly advise taking it to a garage to get it done - they are an absolute nightmare to remove and you will need a genuine BMW one so the cost saving DIY will be negligable.
Hope this helps - there are other threads on this issue on PH by the way

You're in luck, those are exactly the symptoms of a failed sensor. Go careful with the drill if it's stuck and remember the sensor ring!!!
I have an excellent indie a 5 minute walk from my work who is very happy with me for providing him with a lot of work (after I got my beemer 3 or 4 guys here purchased seemingly broken ones too!!) So he does me a good deal, and I'd rather trust him over me!Gassing Station | BMW General | Top of Page | What's New | My Stuff
