I can't find a way to clear past tests from Bimmerlink, so I can re-test. I am trying to learn Bimmerlink w/o screwing up. also, have 1 code I need deciphered - 213901. I think my lean mixture could possibly be from a weak water/methanol mix which has been addressed. before I go to Renn Haus in Sarasota I want to make sure I'm not doing anything stupid. Thanx

How do you re-set Bimmerlink to run because it retains data & stays on original test ? erase Info Memory ? I would imagine it would either cast off some codes or retain some ?
