hi all
i have a 2014 m135i with 40000miles(64000km) with two separate issues i would assume
ISSUE 1
i have been getting this weird vibration sound(its sounds metallic) through out the rpm in comfort and sport mode and when the engine is hot and cold.
(BMW have checked the ASD and it is not the cause of this sound)
ISSUE 2
further to this i have another separate issue where the steering wheel vibrates at around 1000rpm and can be felt touching touching the body panels of the car as well. this vibration gets progressively worse as you accelerate through a corner at bit of pace and as the speed increases to 140kph where the car feels like the alignment is out ( i have just replaced all 4 tires with mpss and the alignment has been done twice in the past (60miles/100km)
bmw replaced the following to try fix the issue
the water pump
tappet cover and seal
oil pump
vannos seals
engine mounts
steering rack
vbelt and pulley
both problems still exist does any know or have any insight into what may be the cause? PLEASE HELP
