Slow down ediff warning 1st day Ferrari owner

Hi, got a f430 a day ago. When I was going to go look it the guy had to go get anew battery for it. I got the car after test driving it as I do all my other many cars and I was certain the mechanics we fine. I have owned many cars before it. A few hours and 222 miles later I got a message slow down and then the dreaded ediff warning. I called my mechanic he told me check the battery cables, they were loose. I tightened them, problem went away. A few hours later went to start the car... doesn’t move. Went boughtnewbattery from Ferrari pompano, hookedup, startedright up, all gears work, all modes work etc. took car to a mechanic in south Florida, he read computer came back with clutch position sensor. Has anyone else had this problem? I read a lot in the forum concerning this issue but none like mine. Any help will be great

Two new batteries?
I’d suspect the alternator going bad.
That can cause all kinds of second and third-order consequences.

Had very similar situation in my 456 right after purchase.

Of all the narcissists I know, I love me the most.

The only real problem here is the approach to the problem.
Start at the beginning:
The battery connection was loose: That will/may result in a no charge/intermittent charge situation.
The car wouldn't start: A new battery was installed and now "all is OK." This is extremely doubtful, as any attempt to start a 360 onward with a low/weak battery will typically set some codes. The codes set are often nonsense.

What to do:
Clear the existing codes in the engine (if any) and in the TCU. Drive the car and see what comes back...
The "dreaded" eDiff problem is a myth in the hands of someone competent. Keep in mind that the "slow down" light has different meanings, depending on the color

If you just bought this car, I'd be concerned....
