I have a 02 Jetta that I recently bought. Glow plugs 3&4 were not working so I replaced the glow plugs and the wiring harness. I have cleared the codes and it doesn't start well in the cold and codes for the glow plugs 3&4 continues to come up. Is there something wrong with the control module? The glow plug light seems to stay on the proper amount of time, I have had another TDI so I know how they should start. Thanks
