Cheers will do. Just took off the shock and greased the air can mentioned from a previous post. You never know. Re-torquing all of the bolts and if it's still creaking then cranks, chainring and motor width compensation screws will be next.
So did you find the source of your creak? Mine has started to make the exact same sound when riding uphill or putting some power down and I've got very few kms on it. I'll look at all of the usual suspects (motor mounts, width compensation screws, cranks, etc.), but as my sound is identical...
