Peugeot 508 BlueHDi 2.0 2017 / Gearbox P2775 & P2779

Hello to All,

I was wondering if someone would point me to the right direction as sometimes I am finding this error when scanning the car with Diagbox. Normally I don't see any warning on my dashboard.
Please see picture error from Diagbox.

Something regarding the One-touch control switch S1 and One-touch control switch S2.
I was searching the internet but nothing to be found regarding this error.

Thank You in advance for any kind of information.

As you can see from the attached links these fault codes refer to intermittant issues with the up and down shift switches. If the car is equipped with flappy paddles then I wonder if they are both fed with a common earth which has a dodgy connection?

Indeed the car is equipped with paddles, so right ... it is basically related to the Shift paddles ?? Maybe loose wire or bad earthing ... something like that ?

[mickthemaverick]

Yes I think that is the place to look, maybe a dodgy connection somewhere in the steering column

Ok ... at least I know where to look now. Much appreciate the input Sir.
