1996 520I SE Auto. Until the vehicle has travelled several miles, the tacho and speedo indicators bounce. The economy meter, fuel guage and digital mileometer do not operate. After driving 6 to 10 miles the instruments start to function normally.
Starting the car later in the day all is ok. Its just after the vhehicle has been left overnight that the problem seems to occur.
All other electrics/mechanicals are fine.
