E30 Zone

Ive been told that i need a replacement ecu system by BMW at a cost of a grand !! symtoms are abs and traction control light on also speedo working now and then. Any one got any ideas or does anyone know of a e39 zone. Thanks for lookin.

I'd get a second opinion dude, never replaced the ABS ecu in 5 years of BMW spannering ( professionally )

sounds more like a duff speed sensor to me, or corroded contacts somewhere
