Default Psd anti lock differential off dash warning
Hi folks,

I am trying to disable the dash warning anti lock differential off message on my 1990 s4 . Everything works as expected with the system so I just want to switch off the warning message .I understand that if you disconnect pins 3 and 9 from the controller under the dash that this may work ? if anyone has done this and if you have any photos of the exact location of this controller and the 2 pins to disconnect that would be very helpful.

thanks
Scotty it

Why don’t you diagnose and fix the issue causing the warning message?
Don’t believe there isn’t a problem either the ABS or PSD system.

Hi I don’t have a diagnostic tool for this car but I have checked a lot of the known items so far and spent a lot of time on it including abs sensors , grounds wiring psd flush, relays etc .abs work fine as does the psd so I am at a loss as to why it’s still causing the warning message which I want to try and disable or disconnect from the controller that sends the message to the dash

any suggestions welcomed

thanks
scotty

Does the warning message come on when the car is started and just sitting still, or does the message only come on, once the car is moving?

Does the light always come on, immediately after the car moves, or is the duration of time before the light comes on variable?

It usually only comes on after I drive about 20metres and when the speed increases
