Glow plugs wont have an effect on power. they are only used for the initial starting of the engine in cold weather. diesel engines can generally run on their own compression alone (the compression can generate enough heat to ignite the air/fuel mix).
The diagnostic machines are ok mate. nowhere near as good as the proper job, but good for a bit of DIY fault finding. if you can pull the codes and google them you will generaly find out what they mean as a lot of them are generic to all cars.:
