Fuel injectors

My M is only firing on 5 cylinders. Spark plug, coil & compression is OK
So I'm going to buy & fit new OEM injector to that cylinder. Is it essential to recode it ?

Best engine oil for Z3M

Hi
When I put my reg number in
Halfords site says - Castrol Edge 5W-30 M Oil
Euro car parts says - Castrol Edge FST Engine Oil - 5W-40. This has titanium in !
Any thoughts which might be best ?
Thanks

Garage has determined that misfire's due to a faulty coil pack. The bulk head end one that is more inclined to get drips of water on so most often packs up.

I'm surprised how often my radiator fan's comes on even when not queued in traffic.
I even put the heater fan on directed up the windscreen to lose engine heat without heating me, but no difference.
