Hi
My memory seat is misbehaving like it goes opposite of every input and steering wheel does not move at all so i checked the bcu compartment.
There is a black extra socket in there.
Any ideas??
What can cause these symptoms?*

Found out:
c0255 main haness to seat harness...
What is this for??

C0255 is the plug that takes all the power/signals to the seat, it is yellow so also has air bag control wires as well....

Can't help with your back to front seat, maybe try the plug for security and/or corrosion... Pete

But it is not connected to any where it is black i guess @haylands

If it's not connected then the seat won't work at all and you would have an air bag malfunction light on...

This is that plug..



It lives here... (seat unbolted)

Having stripped my seat down to fix the heating elements I think you'll find that plug goes into the other side of the yellow connector that Hayland has shown. To make life easier the yellow plug can be unclipped from the metal bracket and you should be able to see where it clips in the back.

I remember now, that's not C0255 it's a spare one that isn't used on mine, you haven't filled in your vehicle profile but if you have the same model as mine then it's not used and nothing to do with your issue...

I would guess your problem is the driver's seat ECU which is the switch pack.... either that or the BECM.... Pete

Vehicle is 03 td6 @haylands
Thanks for info
I stripped the ecu nothing seems burnt'all clean

Maybe worth getting the codes read, it may have logged something to give you an idea.... Pete

That's the BECM, the ECU for the seat is in the seat switch pack... You can sometimes see a problem but a lot of the time there is no visible damage, the parts fail internally, there are places that can check these ECU's but there is little you can do yourself, that's why a code read may be helpful...  Pete

There were no codes.
