Hi Everyone, Newbie here so please bear with me!

I've been battling with a problem with our Touran for around a month now, I should start with some background information.

Ok, so one evening I dropped the kids off at a group they belong to, no issues, I pulled up in the car park, they jumped out, I came home and waited to pick them up. A couple of hours later got a call to go get them, stepped outside, tried to unlock the car, indicators flashed, doors didn't unlock. Manually unlocked the drivers door, tried to start the car, it cranked but engine wouldn't start. I thought it was battery related as the car is second hand and I've no idea when the battery was last replaced if ever. Got a friend to pick up the kids and over the next week arranged to buy a new battery. Wife went with her Dad picked up battery came home fitted it and the car started, problem solved or so we thought! I came home home, tried to start the car, it started for about 10-15 seconds then the engine cut and the MFD said "Switch off ignition!". After that, interior lights were out, no central locking, horn didn't work, windows didn't work, and the car was back to cranking but not starting.

Fast forward to now!

There has been much reading, researching and investigation and I don't want to chuck it all into here for fear of overloading everyone! I started typing everything that we've done but it might be better to start with a question and work from there!

So what I'm trying to work out is if I'm seeing a wiring or module fault. I'm erring on the side of module failure because so many systems have gone offline at once.

Can I start with asking if a damaged BCM could cause the car to crank but not start, seems to me that the immobiliser is working otherwise it wouldn't crank?

I appreciate this post isn't well structured and I apologise but any replies would be welcome. I can give more info about what we've done as it becomes relevant.

Thanks in advance, I do have the results of the last VCDS I ran which I'll paste below for anyone that fancies an extra read! :-)
