As newer BMWs do not come with service books anymore, it's impossible to tell from the i-Drive service history page who has carried out work on our vehicles; unless of course it's done during our ownership in which case we know where the work was done. This has been discussed on other BMW forums and some are compiling their own dealer code lists as information is fed back from forum members. The best list I've seen is at f30.bimmerpost.com but I won't reproduce it here as I don't have permission to do so. Can we have something like that on our forum please? I have service history from dealer codes 08611 and 44831 but haven't got the foggiest idea who these dealers are. Update - After talking to BMW HQ I now know whom these codes belong to, see below.
