Thats great, ive owned mine now for 18 months or so, had to replace the NAV, upgraded iDrive, fitted ipod kit, repaired trans mechatronics adapter and sleeve, PDC sensors etc... I agree, the knowledge on here is amazing, I dont know what i would have done without this forum! suffered in silence no doubt! ha ha!
Anyway im sold on the fuel filter change, will get on on order!
