Foxwell should do the abs light, if it was a wheel sensor it will generally go out after a drive round the block, not sure even the Gap tool will program keys have a look on there web site for info.
I've looked in to the gap iid bt and it looks like it will do everything but is locked to one car and I think that's a bit tight.
Having read the code and fixed the problem the foxwell should clear it, out of interest what is the problem ?Sorry that should say airbag light.
