^^ cool. good stuff. :tup:

yah, sounds like it just didnt initialize correctly during start up sequence then.

In my case, the gear position sensor wire got snagged putting the motor/trans back in the car from the nose. The s-mode warning came up right away, the gear number under the tach was blank.


Im now looking for a new plug and wire combo to splice together since I can just slide a new connector on with the the trans in, since the old connector is fubar.

zzzz

Aaaah, good old 2010.

Gonna dig this thread from the grave once again, as I experienced the same warning yesterday.

Had a full speed pull from 80-140mph and I got the "S-mode warning" on the dash. S-mode was unavailable and the gear indicator went black.
The car behaved normally, but s-mode wasn't working, so rev-matching was not working anymore. I continued the drive normally, after which I turned off-on the car and it all came back on, working no problem.

I have no idea what triggered it, but it happened in high revs while at high speed. Maybe the shorter diff in my case somehow confused the ECU, if it has any values on what to expect? Dunno. I'll keep an eye on if it happens again.
