Hmmm...

My key has a little red transponder in it? I thought EDIS was managed outside of the ECU?

The guy I bought it off had an ECU that he was swapping between all of his 1.8.

I thought my engine/ECU combo was pre PATs and external EDIS?

(O and the ECU I bought of eBay the 2FBC came with no transponder- I using the original key).

I have the blown original ECU (which is also a 2FBC code).
