I have the same problem on my 306 i changed the battery and starting was much improved although i still need to change one of my glow plus i cannot get to * You have probably shorted out the +12v supply wire to the top of the glow plug. It is easily done and is easily corrected. Examine all of your wires to the glow plugs. At the end of each one should be a small ring crimp going over the threaded post and held on with either a 6mm or 8mm nut. These crimps should be only touching the threaded post, and not the glow plug body. They are very thin metal and easily bent to touch the body of the glow plug, hence not giving the heater element inside the juice to work. Good luck space cadet.

glow plugs have absolutly nothing to do with the car not going over 20 mph. sorry, but you gotta keep on em. at a guess i would say it was due to them doing a t-belt and not setting the timing right somehow. but that's just a guess.... while I love my TDI, the service and parts at most VW dealers are at the bottom of the list

sounds like a bad sensor. the glow plugs should stay on long enough to reach a certain temperature, especially when it's cold. So turning off after 1 second is not nearly enough. There may be a problem with sensing the temperature of the glow plugs.

The glow plugs on my 99powerstroke have to be cycled several times on a cold morning. I get a M.I.L and codes 1396/1397.I have put in new glow plugs and a new relay ? ? the relay is closing when key is...


the glow plg system is monitor when the glow plugs are commanded on for more than 35 seconds and when the battery voltage is between 11.5 ans 14 volts. dtc 1395 or 1396 will set on the bank that is reading less than 32 amps or the the bank that is at least 8 1/2 amps lower than the other bank. Loose fitting pins in the circuit connectors causing high resistance or high resistance glow plugs on the circuit could be the cause. A shorted circuit or low-resistance glow plug(s) on the oppisite bank could be the cause. Each bank needs to draw more than 32 amps but not more than 8 1/2 amps apart. Obviuosly your glow plugs are not the problem since you replaced them all. Therefore, in my past experiences I have found the gaskets and/or the injector harness (under the valve covers) to be the culprits. A simple test you can conduct with an amp meter will help determine if you have a glow plug system that is under performing. First let the vehicle sit for at least an eight hour period. Pop the hood and find the Black/Orange wire going from the solenoid to the glow plug relay. place your amp probe around this wire and turn the key to the on position (do not start the engine). You should have an amperage draw at around 200 amp and it will start to drop as the glow plugs warm up. Now if your initial reading is not close to 200 amps, then you have under performing glow plugs. At this point you will have to ohm out each valve cover gasket and each individual injector harness to determine which one is open. At that point replace the defective culprit and clear your Dtc's then recheck.

Hope this helps,

Ron.
