Has my ECU bricked?

[madmadmax]

Ok so the car has been sat for a year with the ECU on the shelf. Now I've plugged it in to pp2000 and I get a message that "fault coad reading has failed"and also get question marks in the live data 


Help me please

remove the ECU and clean the pins with a toothrbrush and contact cleaner. try and do the socket as well and try again.

These guys are very good.  https://www.cartechelectronics.com/   Have used them a couple of times. You could:

> Send your existing ECU for diagnosis/repair (cost unknown) or
> Get them to supply a replacement unlocked ECU (expensive) or
> Source an ECU from a scrappy n get them to unlock it (cost me about £80 recently).

That's not bricked if you can re-flash it. 

What you have is a corrupted ECU - maybe from static/dust etc?

Depends.

Single plug can always do a OBD write whether locked or unlocked. I can unlock EDC15C2s if anyone wants it done... ECUs don't just lose data themselves after sitting on a shelf though.

Reflashing the Flash ROM (program data) won't do anything if the EEPROM has lost data - two separate parts of the ECU. You can't "reflash" the EEPROM with pretty much any consumer tools, PP2k is your only way along with the original pin code for the BSI/CPH module.
