I read that DieselGiant article on testing the glow system. Actually helped me a lot since I've little experience with electrical or working on diesels. (yes I know I deserve 30 lashes with a wet noodle)
The thing I wonder about is the part that stated that we should make sure to only purchase German-made plugs (also referred to in said article as OEM). When I recently bought my Bosch GPs, I noticed that they were made in France according to what was written on the package. Is there a type of Bosch made in Germany and a type of Bosch that is made in France? Brian 83 240D
