I'm sure it can be done to the W208 as well by changing the settings for the rear sam unit to Nethlands via Star, but its a case of whether the Stealer is willing to do it. Apparently, in the UK it is againt some sort of Legislation and alot of Stealers will not do it.
When my car went in for battery recall earlier this week I had asked the Stealer to set the rear sam unit on my car to Netherlands to activate the bleep upon lock/unlock and explained how it could be done (I even gave them instructions which I had obtained from a US Forum on the procedure incase they said it cannot be done which some other Stealers have said to me in the past when I had enquired to fobb me off). In the end the Stealer said it can be done and they know how to BUT they are not prepared to do it. Only way I wil probably be able to activate it is by getting friendly with someone who does have access to Star Diagnostics... as every Stealer I have approcahed has refused to do it or denied knowing any knowledge.
