2004 X5 3.0, 113K miles, I changed fluid, dropped pan, changed filter, pumped back in 6 liters of OEM BMW fluid from dealer. Old fluid was black. But now when I start, shifts reverse & forward but the electronic system has gone haywire. Most warning lights- battery, 4x4, brake, ABS all come on & the engine begins to shut down & cannot drive. Not dared to drive it on the road. Anyone else had this problem? appreciate any help, before I tow it to dealer. Otherwise vehicle in very good condition, well maintained.
