Surf has zero power

[Supernova190188]

Over the past few months my surf has been going into limp mode if you put foot down a little bit too much or go up a hill for instance. However yesterday I suddenly lost all power and was down to about 20mph tops and going uphill not a lot more than walking speed. Seems to have blue smoke out the back. Assume this is sone sort of turbo problem? Any advice? Thanks.

When you say limp mode, have you had any flashing lights on the dash?
