My dealer wanted it to sit. But it has been stated that it is not necessary so long as it sits at one point for that time. For instance , they do it and you go home and park it. That is fine .Anyone else had this done recently? I asked a few dealers and so far have received price quotes from 420$ to 550$.
Some insist the car has to sit there for 8-10 hours while others know that's not true...
I had my 17Z done for about $500. The guys are 100% right. The car can be driven immediately after and all day if you want. The programming will finish taking root over night in your garage.Oh believe me I know exactly that it does NOT need to sit at the dealer.
Funny thing is that one dealer told me that it needs to sit at the dealer so they can warranty the work.
Sadly they are the closest dealer to me.
Luckily I found a dealer about 1 hour from me willing to do it cheaper and they already know I can take it home to let it sit.
That's rather common these days ... "on-the-job training" and "having things done for you" ... expectant of just plugging it in and pushing a button.... it’s more about the fact that the guy had no clue of what this upgrade is all about...
