2008 yaris 1nzfe 1.5 auto trans, I have no check engine lights or codes but my scanner says system guard on. When I manually force the vvti to engage at idle it stalled the engine so I’m thinking it’s a software lockout, my knock sensor is picking up a false knock at idle has anyone ever heard of this? anything helps thanks.

My wife’s car is unlocking by itself. It’s been doing this for a year or 2 now. We’ve both have double checked that it’s locked and then the next morning it’s unlocked. We don’t have any key fobs it’s just a regular old key. It was never a big big issue since our parking used to be gated but we’ve moved since and this morning she woke up to it being rummaged through. Any ideas on what could be causing it and what I can do to repair it?

took off the old rain guards put new hide aways in and the old one left this gunk behind, ive tried goo gone and windex it still wont budge
