DCT failure in 2012 - diagnoses *other* than sensor?

Unfortunately when the DCT light shows and your Cali only shifts the odd or the even gears the signs are no good at all. The scheme below shows how the DCT gearbox operates and 1-3-5-7 are connected to the odd primary shaft.
According to my Ferrari dealer that is qualified by Maranello to repair any DCT transmission 99% of the failures they've repaired are not due to mechanical break downs but to sensors failures. I had a problem with my Cali DCT this year and it was due to the failure of the main shaft sensor but because there are other sensors inside the gearbox in your case the problem could be in any of them. My Ferrari dealer diagnosed which sensor was the problematic one by doing several tests and analyzing the data messages with their computers. As you certainly know the substitution of any sensor needs that the transmission is removed from the car and that's quite a task (in the thread California Gearbox failure I've posted some photos that show how they remove the DCT). My Cali's DCT after being repaired feels much better than ever before and so far is working perfectly.
I don´t know what's your idea but repairing the Cali DCT is a job that can only be guaranteed if performed in a Ferrari dealer that has the level nr.3 qualification and all the special tooling. As far as I know Ferrari only sells and supplies the spare sensors to the qualified dealers.

Wish you luck and a quick solution.

^^^^ This pretty much sums it up.

Yes, sorry to learn of your misfortune. AFAIK, odd/even gears failure has only been referred to as an internal DCT sensor failure. Looks like you may have missed it so here's a very good thread where a fellow fchatter included a photo of the sensor as well as the work order and costs associated with the repairs to his odd/even gear failure.

Hope this is useful.
