Hi chaps

The switch packs always used to die on the s2, not sure if it’s still a problem on the s3. If it is, you need one of these, but as it’s a 350 it will be a warranty issue.

Before that, check all fuses, turn off ignition, wait 30 mins, disconnect battery and come back in a few hours. It’s stupidity may have stopped in typical lotus fashion

Do the lock pins go to move just only just slightly wiggle when trying to lock? That was the symptoms of the switch pack dying. Hopefully it’s not that as they should have improved the part. If it is that it’s a very simple fix

Check fuse 16, 19 and M5. Unlikely to be the latter if you drive home as that’s all battery services.

Does the rocker switch in front of the gear stick do anything?

I did check 16 and was ok.will have a look at the others too.rocker switch is dead

Ok after much fiddling about ,disconnected battery ,left for an hour,connected back up and hey presto....all seems to be good 🤞thanks MrP for your input
