Hi gents!
Just bought a 2nd F30 320i, this one in manual. Long story short, we have 2, both 2013, auto on 100k and new manual on 125k.
The auto has been remapped for sometime now and is a powerhouse! After mapping the manual with the same tuner it has developed a hesitation (Same file so we can eliminate that)
Changed what looks like the original plugs with NGK iridium and the problem has subsided but is still noticeable. I did notice that coil pack on cyl 4 has some surface corrosion (rust) on the outside ( looks like it was never pushed in and sealed correctly)
Could this cause the issue? No fault codes at all coming up? Maybe dirty fuel filter?
Any help will be greatly appreciated :thumbs:
