What are the symptoms of a blown glow plug in a TDI engine? (1999.5 Golf TDI, 1.9L 90Hp) - Should I see the glow plug light coming on while driving, or flashing? (does neither)
My glowing period in these really cold winter days is getting to be (seems like) close to 20 seconds, and I leave the car plugged in all night (now, it could just be the block heater has a bad connection, but it's only been in use 1 1/2 winters - I'm going to get my clamp on amp-meter out and test for current using an intermediate connection between the extension cord and the plug on the block heater where the hot wire can be separated from the others for the purpose of testing current, but lazyness and it being -30°C out have stopped me from doing this test (haven't made my special extension cord for doing test either...) of the heater)... When the car fires it sounds like one cylinder is "coughing"/sputterings for a a little while before it catches and runs smoothly... this might just be the very cold weather we've been having tho.
