New EGR query

[Hendo670]

Hi
I've just fitted a new EGR valve to our2012 Seat Leon 1.6tdi. Yes, it's one from eBay and I know I shouldn't have, but it's an old car.... Anyway, fitting it went as well as it can, given the placement of the thing. However, when I fired it up, I now have a continuous flashing coil light and a different error code(P040800)Sensor B circuit high. Smashing!
Before I had the P0403 code and would only go into limp mode on occasions.
So it would seem to have an issue with the actuator wiring/position?
Has anyone else had this issue when fitting a new EGR ? Really don't want to have to strip it out again
Cheers

Maybe not completely relevant to your current issue, but I'd think that a new EGR would need to get "introduced" to the car's engine ECU so that it could have correct control of it, you can do that using "basic settings" - at least that was the situation with petrol engined cars with an electrically controlled EGR valve.

Thanks for the reply.
From what I've read online, there should be no need to code the new EGR in? I have reset the ECU, but no difference. The thing is as soon as I turn the ignition on the coil light is flashing. Also, the error code can't be erased. Totally perplexed!

There are various different EGR valve part numbers - are you sure you have the correct one?
