Someone on the US forum posted a link to the Volt Service Manual. I'm not sure how much of it will apply for Ampera, or for RHD drive Volts for that matter.

N.B. According to the thread on gm-volt.com the site may have some javascript malware. It appears to be benign but use with caution.

I tried to visit the link above and got redirected around the site a bit. It seems the new link for the European 2012 Volt/Opel Ampera service manual is here.

It's probably best just to read this for interest, actually using it will undoubtedly invalidate warranties.
