4 warning lights at the same time?

Had a panic of a phone call yesterday from my wife whilst driving home from work. 4 warning lights came on at the same time?????
Have absolutely no idea where to start,so can anyone please advise? Photo attached below?

Could be a wheel speed sensor ort he reluctor ring but a fault code scan is the best thing to start with.

Hi same problem with mine, its the abs ring on both my rear driveshafts. rusted up and swelled up, been hitting the abs sensor in the hub. i removed the sensor from the hub and you could see the wear on it, also could see the rusted abs ring through the hole. abs rings £10 a pair but you need to remove the drive shafts p,i,a i have done the near side, old ring just fell off. I dropped the rear of the exhaust and removed the sway bar bolts to allow the driveshaft to be removed

I had exactly the same, and it turned out to be the exact same issue as Rapidspec, but with just 1 of the rear wheels.

got the driveshaft off, used an angle grinder to remove the reluctor ring, cleaned up the shaft and fitted one from ebay for just a few quid. Replaced the worn sensor with a genuine BMW version (was warned off replicas by a good friend who has done ABS sensors on a couple of 3 series he's had). Fingers crossed, all is now fine.

Good luck getting it sorted.
