Hey guys proud and sad owner of a 2008 x5 4.8 recently did the throttle body harness repair by cutting and splicing the harness on the throttle body , I did disconnect the negative battery terminal while doing the job, after I connected the negative battery terminal drove the car around and at heavy throttle the dam pass airbag restraint fault came on seat belt light and airbag light . I tried clearing it on rheingold and no luck it just stays there any ideas or tips , I don't think it's the pass mat sensor also I have already looked up on bypass modules and the BST cable anyways I'm just shocked that rheingold won't even clear it , I've cleared it in the past and it stayed off any ideas? Battery is about 8 months old .

thank you guys
