Hi!

I am getting an error called "Pre-Save Inactive"

Does anyone have any insight on this?

It says to look in the operators manual, but I could not find anthing.

I have a 2004 S430. I think whats happening is that it doesn't switch gears after that error comes up, sounds like its stuck in first or second, and it doesnt let me switch to the manual or sports mode either. Its stuck in comfort mode.

Thanks in advance.

^run to the workshop..its a CPU error.. happend to many W220´s easy fix
but they will probably try to charge you like HELL for it
i hope you have friends at the dealers

I have the same problem with my 2004 s430. Pre safe inactive message comes on and says "refer to owners manual". The operation of the gear box is affected. Did you get yours resolved. Thanks in advance.

Had a similar problem with my 5 series after a wheel spin. It had been snowing and the gearbox got 'locked' in safe mode and woundnt change higher than gear 2. Generally its a CPU problem. Thing is, electronics seem to be one of the most expensive items to fix/change but once diagosed can be done quickly and effectively. Also it defo is something you'd have to take in to ur authorized Merc dealer.
