I have been experiencing this same tranny issue since I got my 2005 X5 4.8is back in July with 74K miles on it. I took it to the dealer today and was told I needed a new fuel pump, fuel filter, intermediate levers and eccentric shafts for the low, low cost of approx $6800 + no car for 1 week. Below is the tech write-up:
FAILED INTERMEDIATE LEVERS.
VERIFIED CUSTOMER COMPLAINT: SES LIGHT ON. CHECKED FAULT MEMORY.
FOUND FAULT FOR CYL #7 MISFIRE AND RANDOM MULTIPLE MISFIRE FAULT STORED.
CHECKED SPARK PLUGS AND COILS. FOUND OK. CHECKED FUEL COMPOSITION.
FOUND BELOW 10% ALCOHOL CONTENT HOWEVER NOTED METALLIC DEBRIS IN FUEL.
PERFORMED INTERMEDIATE LEVER TEST AFTER ENGINE COOLED. INTERMEDIATE
LEVERS FAILED TEST. RECOMMEND REPLACING FUEL PUMP AND FUEL FILTER. INTERMEDIATE
LEVERS AND ECCENTRIC SHAFTS.
Has anyone done similar repairs to their X5? I really don't wanna dump almost $7K to repair costs. Any advice?
