Toddy2 i have taken out my glovebox and the only module i can see seems to be my alarm module it says texon on it.
I have also stuck my head as far under the passenger seat as i can and it looks like there are no modules under there just a couple of wires and connectors that seem to dissapear into the seat base.
Do you have any other places i should check?
Thanks for your help ;)

Well this is mad i have lifted the carpet in the rear behind both seats and had a good look and feel around but nothing.
I see on the passenger side a rectangular cut out in the top layer of paddin thats looks like its been cut out to allow a control box to be fixed to the floor pan, however all thats under it is more thicker padding and nothing under that just the floor.
I managed to sweep my hands all around under both seats as far as the raised part of the floor at the front end of the seats and found no control box.
This is mad there has to be 1 somewhere lol.

Ok i have fitted the new ecu and things look promising :) please see Addgo.jpg attached.
I do however have a question if anyone can answer please, i have a fault saying "Engine Ecu Permanent fault. Catalytic Converter upstream temerature signal. Short circuit to earth. (please see EngEcu.jpg and EngEcu1.jpg).
This fault says permanent when reading with ignition on, if then read with engine running it will change to temporary.
Question is how to fix fault & will fault stop Addgo from adding the fuel additive while present?
Thanks in advance for any help:thumb:
