Hey guys i have a issue with my dme so when i purchased the f30 n20 i inspected the dme and it had like brown pins almost like if they were burnt and cleaned it off and then got a p00bd code checked for leaks checked the MAF sensor and cleaned it and replaced it 3 times and nothing but now the weird thing i have no check engine light drove it everywhere and its just there pending after 5000 miles driving still no CEL and just stays in the pending status but when im coming to a stop it shutters like it wants to stall and then sometimes its jerks but when my car is at idle it has erratic idling and it has like shuttering like it wants to stall and then goes to normal and when i put the ac it starts doing it again and then goes back to normal then i drive the car and the shutter stops and when it brakes its like butter with no issue so far what ive done is....
changed spark plugs
changed fuel injectors
high pressure fuel pump
change the charge pipes for new ones with new seals
new ignition coils
changed both up and down o2 sensors
still have the same issue dont know what to do next ?
but i guess my question is can the DME still be faulty even tho ISTA program diagnostic says its functioning properly ?
bmw community please help!!!!!
