I think at some other time or in another thread I posted something about this, however, I don't believe anyone had any good thoughts that they'd had with theirs or ideas.
Just checking in to see if anyone has had a completely random/intermittent wrench light that, for me, only comes on at vehicle start up when it does come on. Other things I've noticed is when it is going to come on I know right away before the cluster cycles completely because the car almost sounds like it is going to stall out right after start up like it is stumbling or getting to much fuel. If I shut the car off and let it sit for roughly 2-3 minutes and fire it up again, so far, the light has gone out each time.
When I brought it in to the dealer I think it was only a couple days prior when the light had come on and the only codes in there were lost communication with the PCM ( I do not recall the code and do not have the paperwork handy). I asked if they could do a PCM update while they had it just to see if that would help since it did not seem/sound like a throttle body issue and I've still experienced it at least once since then.
Anybody else experience this same thing that I have? If so what work was performed to remedy the issue?
Forgot to note, this is on an S550 21 Mach 1
