Bmw m5

I recently left my 2012 m5 into BMW to get my dab radio fixed!

They upgraded the dab radio with a new programme, which now has stopped my m car going over 4000 revs in neutral. BMW say it is an upgrade can anyone give me advice on this as I bought the car with the knowledge of it being able to rev over 4500 rev of which it did until this upgrade.
