What I suggest is first go to a shop with gt1 and check whether the previous owner had actually registered the battery, this is if the battery is an aftermarket ones, my previous owner put in an Ns70 which is too underampped (word?) for the car. My mech advised that I change it to DIN88 which removed the restraint error that I had before but a few weeks after it came back. I suspect that the mech did not register the new battery using Gt1. I am going to obermaier to get them to register the new battery and maybe check the IBS (Intelligent battery sensor) too. This is because, after researching on the internet, i found out that the car will shut off restraint system, and a few other electrical components to protect the battery if its underpowered at cranking. The best bet is to change the battery at AB with original battery which I think will fix some (if not all) of your issues. The dealer will know to  reset the battery through gt1 as they change the battery too. I think it costs about RM1k++to do it at the dealer. Try calling them to find out.A cheaper alternative is to go to a reputable mechanic insisting that you need to change the battery only and needed that they to register it using gt1 too. Get Din88 or higher amp ones.P/S - SBK is on the +ve cable while the IBS is on the -ve side. :top: BTW, what size is your battery now?</blockquote>
