Hello, 

I have a friend that just bought an 3 series, e90, 2008. 
Interior was changed, as former owner said , and has three faults: 
MRS: belt tensioner, driver
MRS: safety battery terminal 
MRS: communication fault, seat-occupancy detector, passenger 

Is there any way to code errors off and everything to work normally? 

As i know seat-occupancy detector is easy to remove, but i'm not sure about safety battery/belt tensioner(belt tensioner needs to be replaced?) 

As i remember well six years ago, i had e87, 2005 and error with safety battery terminal that i went to a guy and code the error, disconnected the black wire on batter, there's a little connector, if i remember well. 
Anyone can give me steps/can help us(me and my friend) remote? I have dcan cable. 

Thanks, 
Adrian

install a 2.2 ohm resistor and the problem is solved, and you still have to disconnect the plugs when coding the diode.

I would really encourage that they replace the belt and tensioner since that really isn’t safe to just code it out however the battery safety terminal can be coded and that’s up to opinion but some E9x come with it and others not.

the wiring of the E90 was modified in the LCI version, check from the Frm outputs if they are correct and then code, it happened to me many years ago.
