Vw polo 9n 1.4 p not starting. Bky engine

[vw_99]

I have been asked by a friend to have a look at his polo.
He has just bought it and drove it 50 miles home. Now the car wont start. It turns over fine, battery is a bit low at 12.3v but even with a jump pack it will not start.

Plugging it in 2 codes came up.

17766- cylinder 2 ignition circut open P1358
18049- check DTC memory of A/C ECU P1641

Both codes under engine management.

So far have changed coil pack on cylinder 2 for a new bosch one and that has removed code 17766 but it is still not starting.

I have scanned the A/C side and there no fault codes there.

Has anyone came across this before?

I am thinking either crank/cam sensor but live data records engine rpm at 240 ish when trying to start it.

I have not changed the plugs yet but have removed them and had a look at them. They look newish. I am going to try get a coil pack tester light thing and see if there is a signal going to the coils.
