Hi guy would anyone know if this could be repaired or has it done too much damage. This has been the cause of many electrical faults I've got. And I even smelled the burnt puff it gave off . Thank you.

At a glance I'd say not completely beyond hope, but it depends on what's under/in that crusty mess by the blow-out and how much electrical violence the other chips were subjected to w/o any external signs. Worst case, they're all dead.

Also, are the chip even available? If any processor or memory, is the content?

That looks like major high current short or reverse voltage damage to the chip.

If you are looking to repair maybe easier to source same BSI and swap or clone EEPROM from your board

I've now fitted anther BSI ECU my rear light faults are all good now but I have an issue with my headlights band side lights. My side lights are on when the stalk says off when I put the side lights on the stalk the head lights come on and then when I click to head lights they go off. I think the ECU and BSI came from a Pug with auto lights could this be the problem?

Yes you need to tweak the BSi configuration with planet/diagbox to reflect the equipment fitted to your car, and as above they need to code the radio with the new BSI VIN.

DO NOT on any account change VIN in the replacement BSI
