Thanks for your response. I have two replies.
Yes, parking sensors are standard on the 320i M Sport 2013 model on the rear, just not on the front, hence my question. My BMW local office have said they will fit colour code front ones for around £300 (so not that expensive).
If not on the key fob then where are the services stored? as it does not come with a service book. Again while waiting for your response BMW has indeed advised that everything is on the fob and car system this is why there is no service book.
I can understand why your response differs hence the OK service rating.
right, sensors are not standard on the front, that is what I meant, per your question
if your dealer will install front distance conrol for that price, then you are fortunate as most cars require a full bumper replacement (hence the cost) to retrofit. without the vin of the car I cannot verify exact retrofit requirements, and the usual requirement is a new bumper.
my understanding is that they key does not store service history, the key provides the vin, which a dealer can use to look up service history that has been recorded on the bmw central servers. In any event, there is no service book for this car, it is all electronic.
