Great thread. Just added alot of power to my E90 now I'm getting the same code, 4F8A
Serviced the entire Mechtronic sleeve 3 yrs ago. Seals selinoids the works. I must have done a poor job. Noticed a squeak 'boop' sound from time to time when the car would shift. Mostly when putting around. Ideas? |
