I'm not a trician. Looks like you've done everything I would think of. Only place I would check further would be the plenum chamber where the ecu is to make sure it's not flooded.

Normally the 1.8 ecu is ok as they are a sealed unit unlike the diesels.

Check the ews box for signs of water, it’s located on the drivers side a pillar, if you remove the lsm and shine a torch through the hole you can see it.

Hi Trikey, is this the grey box on the A post just to the right of the LCM, didn't see anything nasty around it but I'll pull it out and have a good look at it
Thanks

It is a failure of the circuit protected by fuse link 11 in the engine compartment fusebox.

It comes in direct from the fusebox to pin 20 of the LSM connector, the cable is brown with a light green tracer.

You lose among others, the offside dip beam, and the OSR indicator

Have fun

Brian
