For the last couple of weeks I've found that sometimes when I plug the charger into the Ampera, it didn't start charging. A quick jiggle of the plug in the socket on the car was always enough to get it going.

Then it started taking a bigger jiggle or an unplug and re-plug. But still not too bad...

Last night, I couldn't get it to charge at all. Tried the fixed box/cable charger and the mains one, same with both --- so I surmise it is an issue with the car, not the charger(s).

This morning I've managed to get it charging by using the fixed charger and inserting VERY FIRMLY into the Ampera's socket, but clearly something is not right.

Any suggestions?

Sounds like dirty conatcts to me. You could give everything a squirt of WD-40, but that's only a water-dispersant I believe, not a dedicated contact cleaner. Better would be some of this:
WD-40 Specialist Contact Cleaner 400ml

It's not unknown (= happened to me) for the car's socket to fail, and short-circuit internally & try to blow up your EVSE. It's a known problem, and those sockets got changed under the HV warranty, but that's expiring soon for most of us. I suspect a hairline crack developed & damp got in.

The charge flap is also poorly designed - water accumulates in the rubber seal thing on the flap when it's rained. So I think it's very important not to let any water sit around anywhere near the contacts, ever. After a rainy charge, I carefully wipe the inside of the seal dry with a hanky, and wipe round the metal alloy bits as well, before closing it all up.

Thanks. Can't get out to the shops for that; any other recommended solvents? We have the usuals, e.g. petrol, white spirit, regular WD40, maybe a few others...

check (with a torch!) the socket on the car, bugs and beetles can get in and prevent the plug going fully home. This then stops the latch operating on the plug and no charge :(

Right, well, things are improving. I cleaned it up a bit with WD40, and also investigated for bugs. Where the trigger-operated 'clip' at the top of the plug goes, in the socket, was a small piece of black plastic. Pics attached. It's about 10mm x 8mm x 5mm. It wasn't blatantly blocking the plug, but clearly it interfered with the clip and now I've removed it the car is happy to charge.

The plastic piece does not appear to have come off our regular charge plug, nor the mains-powered 13A one we sometimes use. We can't think of any other charge cables we've used for some time. Is it possible it's broken off of the car's charger socket?

It's also not clear to me if there's some (electrical) switching going on in there that it might be involved with, or whether it's a purely mechanical thing.

So, we're happily charging again but would be interested to know if anyone knows what's going on, whether the little plastic jobbie is important for anything, etc.

Not seen that, but glad to here your working.
The plug contains a microswitch operated by the latch, the car detects this as "Plugged in" Its actually the PP wire I think? If it fails to latch your stuffed.
