So, the only questions I have are about clearing the codes. First off - is the BT tool the only known-to-be-reliable way to clear the proprietary BMW codes, or is there something simpler/cheaper? The BT tool looks and sounds great, but I just want something quick for now.
Secondly, suppose I don't clear the codes right away. Will the car remain in limp mode, or will it realize that the actuator is replaced and attempt to allow the car to function normally? I will want the codes cleared out asap, but, unless I can just go buy a cheap ODBII scanner at Costco to do the job, its not going to be possible to do that today. And I'd really like to know by EOD if I have accomplished the repair successfully.
I doubt the CEL would just clear itself to be honest. Maybe disconnect the battery and let it sit for a while, and hope it goes away? Another option would be to run to Advance and borrow their OB2. Might be worth trying these 2 things out before having to buy BT.
