    so thank you MackemX
    the old one is on its way to you and your products get my support
    it's no problem at all and it's great to know that mine shows as OCCUPIED in PA Soft also as I've only ever tested with INPA. I'll send you the invoice now (kidding of course)

    but seriously it's a bit disappointing that people are unaware when buying them unless people like you & I are able to test them. Just today, I've just been sent another bypass from a 5 Series owner on a different BMW forum that he got from another eBay seller and again it's UNOCCUPIED. It's just wires wrapped around the component inside and it's not even complete as it's missing components! I've even got links to a thread on another BMW forum where this seller actually asks for a solution to the OCCUPIED issue (from last year!) but I'm not sure if I can post the link on here.

    either they don't have a clue, or purposely do it or maybe they know if it's OCCUPIED that it sets off the seatbelt warning in some BMW's so they don't want to support that as they don't have a valid solution. You can't use a seatbelt insert or leave the seatbelt in for the MOT as that would fail! Good news is that I know of 2 ways to bypass this also that do pass the MOT and I think I'm the only one as I've never found anything anywhere that shows the solutions

    as for the pre-tensioner, you could replace the cable yourself to be honest as long as you disconnect the battery. In most BMW's, it's just 2 wires that run from the buckle area to the main plug under the seat base. If you'd like to do this or know a little more then just say as I can call you if you PM me your number

    cheers

    yeah the E46 normally resets itself unless you've got other air bag errors (example you've unplugged the 3 wired white plug that goes into the black box). I'm too lazy when testing mine to disconnect the battery and I've seen that the BMW seat occupancy mat repair job instructions only states to turn off ignition and strip seat down etc and replace mat but it doesn't mention disconnecting the battery

    Yep, I've seen that too.
    If you ever have a light on that has switched itself off for any reason, it is going to be the sensor mat.

    how about; I have retrofitted sport seats to comfort ones (half electric to full electric). the comfort ones have additional back rest pretensioners which by schematics are connected to the pillar modules. I run the cables but have got errors for both passenger and driver seat - i guess i need to code them in. however, i once pulled the cables for pretensioners without disconnecting the battery and now have permanent restrain system error. I can erase with INPA but it comes immediately back how come I cannot erase the error?

    those pics are just from reading all the error codes aren't they? top option isn't it but I can't recall the exact name (functional jobs?) but if you go into specific sections then it gives you more detail. I can't think off the top of my head how to get it plus mine is an E46 and yours is an E60

    it's as you said as these are the errors

    984F Coding, firing circuit, front airbag, left, stage 1 (E85), or active head restraint, front left (E6x), at variance

    985A Coding, firing circuit, front airbag, left, stage 2 (E85), or active head restraint, front right (E6x), at variance

    9AF3 Driver seat belt tensioners firing circuit resistance is too small


    I guess you need to focus on the cable from the pre tensioner to the yellow block under the seat. Just check that everything is still OK and maybe check and clean out the connections. I've seen people have also sprayed something on the connections but the exact name escapes me

    back to this again, this thread regarding Pre Tensioner has a pic of the menu I'd been thinking about but again it's the E46 version
