If is the same coil packs Rover adopted under BMW control -- which don't need introduced to the ECU. --- but knowing BMW the same guys who sell
BMW Minis without the special key to change a wheel!!!!!!
Of course if a fault code is logged it will need cleared -- via the EOBD connector.
Be aware that it is really a good idea to change the "leads" rubber and plugs at the same time as a coil pack -- a lot of coil pack
failures are caused by plug & plug lead HT faults.
With the Rovers a lot of HT problems are solved by fitting new plugs gapped narrower than the spec. Setting the gap to 0.8mm (as Rover used to use)
stops a lot of low speed misfires that develops as the plugs age.

Quick search revels this is a major BMW problem, as with PGA group cars it can cause ECU burn out.
Root cause is probably excessive HT voltage required by the spark plug causing the insulation in the coil pack to fail.
BMW have been recommending plug changes at 100,000 mile intervals ---- !!!!!!
I thought Rover were bad expecting 60,000 miles out a set of plugs.
With Rovers we learned the hard way and now change the plugs at 30,000 using only the specific OEM plugs and gap them to the narrower gap.
