It will be the abs/dsc unit, rebuild time unfortunately seems very common on the SI models
It may be the pump but, on the other hand, you may be lucky and it's just a sensor.... first thing to do is pull the codes....
If you can't pull the codes, there may be a member nearby who will be willing to assist.... or you may want to think about getting something like one of these
If it's the pump you should see something like
005DF0 DSC Hydraulic Unit: Pump Motor
005DF1 DSC Hydraulic Unit: Pump Motor Connector Fault
Then you're heading for replacement/rebuild - I seem to remember people having good service from ecutesting.com
If you're lucky it may just be one (or possibly both) of the pressure sensors - this is normally shows as just handbrake & dsc light but can trigger all three (it did for me). The readings from the two pressure sensors have to agree within a certain tolerance and if one goes tits-up you'll get the warning lights
If it's a pressure sensor you should see codes like this telling you which sensor is at fault
5E24 Pressure Sensor 1/2 not plausible
5E21 Pressure Sensor 2 Electrical failure
Replacement sensor was about £90 and took 10 mins to fit (27mm spanner) plus the time for a brake bleed.

Could also be a fuse. Check the manual there are 4 for the abs and dsc system.

Mine lit up when the battery got a bit low. A brief charge and a few drives to top it up and all was well again. I feel lucky that it wasn’t anything expensive, this time.
It’s clear that there are a number of possible causes for these lights to come on. Definitely worth taking time to carefully diagnose the problem before jumping in and spending a fortune on something that may not actually be the cause.

Have you checked the brake fluid level? I had the same happen after I had a front calliper change. Hose had a slight leak and as it got low had all 3 lights come on!! Took it back to the garage and they fixed the problem.

Thanks for the info guys just a quick update. I got in the car this morning the lights were still on I drove it around in heavy rain for about 40 minutes and after 10 minutes the lights went off, they came back on 5 minutes after that then went off again, the warning lights have been off for about 2 hours now. Im still worried though and I am going to order this as suggested by you guys.

what a joke.
Thanks for all your help ill keep you updated.

I had the same three yellow lights shortly after I got the car. I took it back to the garage and they fixed it pretty quick, said it was to do with front geometry and track rod ends being replaced for the MOT and the tracking not being set properly (twats!), causing the steering angle sensor (I think it was) to throw a wobbly.
Is your steering wheel straight, when your driving in a straight line? Mine was slightly out and the code came up after driving on a long straight piece of road for the first time, chatting to the very apologetic salesman, he said the other things it could be was the angle sensor itself or maybe one of the ABS sensors.
I can't remember if he said they needed to reset the angle sensor to clear the lights, but after the tracking was done and the steering wheel centred all has been rosy since.

UPDATE.
So my OBD came today and a scanned the abs system and all it gave me was this.
Pleae send the date to customer service!
03 03 5a 80 00 00 06 76 91 62 02 20 00 30 00 00 20 06 10 30 18 00 00 00 00 86 00 00 00 00 00 00
Not a clue as i havent used one before, when i scan other parts it comes up with the part number etc but when you press back it asks you if you want to diagnose or dlete the warning light, when i do it to the abs system i dont get this option, it just shows whats above.
If anyone can help me out id appreciate it.

What obd reader is it? Not all of them actually read bmw abs and airbag modules. I had to buy a specific one from bavarian dominator. If it's some cheapo eBay one it's probably not going to help. Mine for instance pulls this.
These were my abs and dsc faults.
The 3 warning lights on my dash came and went as the ABS/DSC pump played "now I'm faulty, now I'm not" for a couple of weeks before finally deciding "yep, I'm definitely faulty" so don't read anything into the warning lights disappearing for a while.Esper06 said:
It was stuck brushes in the pump (probably not driving it hard enough to activate ABS as much as I should have) and an overhaul saw it fixed for a good price (compared to replacement cost).
As mentioned above, my codes were also 5DF0 and 5DF1 (read with INPA, and I think CARLY will show these codes as well)

Don't immediately jump to replace/repair pump. These also commonly occur when the steering angle sensor has been knocked out of shape. Often happens after doing tracking etc.
Come to think of it. I couldn't pull the codes when I put the module back in. I didn't connect it up correctly. So it could well be the motor actually works but the abs ecu does not. Hence no codes being pulled. Give the connector a wiggle. Mine was filthy as well. Could be just dirty and giving a s**t connection.
Happened to mine not long after taking ownership. My car had really bad alignment (steering was like 20 degrees off). Had the car aligned, drove for weeks ( months?) Then one day lights came on as I was going through a bend. Tried doing a soft steering wheel reset as suggested somewhere I can't rememver (fulll lock each way) and it would intermittently make it go away.
Ended up taking to my local BMW specialist Indy and it was just the steering wheel sensor that needed to be reset. No biggie. Hopefully that's your issue too!

UPDATE.
Took it to a garage and he suggested that i get a replacement abs motor/pump, all in all this will set me back 522 with labour charges. I hae a feeling that i could get this cheaper but i don't know what to do. I have 14 days to get this fixed as my mot is coming up
Any suggestions or does anyone know someone else i could take it to.
