Just started doing that on my '03 tdi after running through a car wash. After digging in the 2 maintenance manuals finding nothing got on line. Seems the most common cause is both break lights failed. Checked mine and both are bulbs are shot. Too late and cold out tonight bit I will replace them tomorrow and hope that cures it. Could be many other things too. Check the tdi forum. Might want to have your codes read just to be safe. I had no check engine light but checked codes anyway and had no codes.
when the glow plug light is flashing during driving it is not the plugs that need replaced it normally means you have a bulb blown most commonly one of your sidelights and once replaced your glow plug light will stop flashing
I don't know what YOUR vehicle does specifically, but most diesels have "glow plugs" that come on when the engine is cold. The glow plugs warm a spot in the cylinder making the engine start much more easily, especially in cold weather. I can't speak for YOUR engine, but in general, there is usually a light on the instrument cluster that flashes while the glow plug is heating. Once the glow plugs are up to temperature, the light stops flashing and you can start the engine. If there is any doubt, read the section of the owners manual that describes the operation of the glow plugs.
Follow the glow plug supply wire from the engine to the firewall. The small box mounted there has the fuse mounted under the cover.
you need to check your glow plug relay it is most likely going out you can jumper it to see if the glow plug light will come back on to start engine
I imagine that if the light is blinking the engine most likely has a glow plug out. This can often be tested by removing the preheat harness from the time/relay and using a test light. Attach the clip of the test light to the positive connection of the vehicles battery. Then probe the terminal of each glow plug, you might have to remove insulators and things to get to them. The result, if it lights up its good, if it does not, replace.
Contact the great guys at bongo.com and ask them to send you PDF of how to read the codes.
You have a glow plug failing. The black smoke is unburned fuel.
Why are you illiterate.
The glow-plugs are located under the valve covers. There is a single wire that comes out of each injector harness that powers each glow-plug. Disconnect the single wire from the glow plug. Connect the gator clip of a test light to a positive and probe the glow plug terminal with the test light. If test light does not come on the glow plug is bad.
This test will determine what glow plugs are working. ( It will not determine a partially burnt plug ). Disconnect the glow plug wires at the plugs .( You must unplug all of them for this test to work ) Connect a test light to the positive terminal of the battery. Touch the electrical connector at the end of the glow plug with the test light. If the light goes on the glow plug is working. Make sure you touch only the electrical connector on the plug. If you touch any other part (metal) of the plug the test light will light giving you a false reading.
glow plug heater / ckts failure..
as far as i know C3's don't have a glow plug light or only use it when it is very cold i.e below freezing
