Problems: It all began when the off-side drive shaft split. I have since replaced that however the following problems now exist. The speedometer reads Zero, the fuel Gauge go's from the current level to zero and back as the level in the tank changes. I have codes P1049 and P1528 that appear as soon as they are reset, I can keep doing this reset and the codes are back within 30 seconds while the engine is running but the car is stationary. I have checked the wires to the speed sensor on top of the gearbox, Looked generally around the wiring and checked for loose wires. Any help would be wonderful.
