The ecu relay powers the fuse via the internal circuits of the fuse box (hence why we thought the fuse box was faulty), the wire to inspect closely is a Brown/white wire, this supplies the ecu relay with a ground from the ecu. This wire goes to Pin 16 of the fuse box plug XE3, it comes from Pin 62, i just rechecked the colour and its possible it could also be a Brown/Yellow wire the pin assignment will be the same though just a possibility of two colours.

Thank you. I will check this and get back to you.

Thanks

Hi @andyl ,
I removed the cable from ecu to the fuse box yesterday & took the inner cables out of cover. There are about 30/40 cables inside. As you suggested had a look for brown/yellow cable. One small part of the cable was badly corroded so I removed the corroded part and then re-join the cable, reassembled the whole lot back and the car started fine. Had a quick drive for couple of miles and it seems to be fine - no check engine lights or anything. There are some error codes but I guess these are the old ones and need to be cleared.

I broke few holders while removing the cable but replaced these with cable ties. Overall took me about 2 hours to do all this - started at 10PM and finished around 12 in the chilling cold but at least (fingers crossed) managed to get it fix.

Once again thank you very much for your help @andyl. You are a ⭐⭐⭐⭐⭐
