Check fuse 19 in the fuse box

Could this be a ECU fualt ?

on the ECU does the last letter mean any thing or is it that as long as the numbers match

If the diagnostic port has power you should be able to access other control units,

plug in a launch code reader

I shouldn't think so,if it works for the Skoda it should work on Seat,have you checked the fuse i mentioned?

[fra21r]

yes checked all the fuses drop the fuse box down checked the hevy fuses at the back
checked the wire out the back of the fuse box had not been cut
checked the wires at the back of the port
red wire had been striped back and retaped the reason i dont know

You should have power on pin 16
