VW Passat B6: 2.0 TDI 16V BKP Engine - Glow Plug Voltages During Cold Start and Proper Operation

Question

Hello all The frosts came and my passat b6 ,, 2.0 TDI 16V BKP engine '' stopped firing yesterday morning without a problem and in the afternoon it no longer turned off, but after a while went out I checked everything and Aku is ok the glow plugs I checked and seem to be in working order...

You need to check the candles, the voltage says nothing about their heating. You have PWM, and the meter for 35 zlotys doesn't overwhelm it.

When it comes to candles, I checked by applying a battery cable straight to it, and 70% spark on each candle, so I can say that they are ok, I was afraid to unscrew them for fear of breaking, first I'd prefer to consult with someone the voltage that goes on the candles because in my opinion if the engine is cold then at least 5 seconds should be 12 vau me it is only a second I have tried even with the temperature sensor detached but it is the same. As for the meter, I do not know why you immediately assume that 35. For your awareness, although I do not know if it is a helpful meter is FLUKE 189, so a little more than 35 PLN

Use a 21W light bulb if the voltage is right, you'll see. Second, ask the driver if he has any errors. Third, measure the current of each candle separately.

Oki tomorrow I'll try to check the light. I also have a Passat b5 1.9 at home and there, after turning the key, the candle indicator lights up in cold weather for about 5 seconds and only then goes out and here after a second and this confused me and I don't know about PWM in cars.

B5 B6 is the divide that shares them with everything.

You will burn such a candle as you give it 12V.

Anonymous · Answer

It won't burn because the glow plug is on 12V. Although what is the method of checking the glow plugs? And how do they turn out to be short-circuited and what ?. In my opinion, the reason must be different than the one mentioned because there are many questions than answers. In my opinion, the reason is this: Not the right fuel (paraffin) or a clogged filter, which should have started from this, and also connected to the computer. Regards.

It is not. PWM are controlled, each separately.

Exactly, e.g. the candle in BLB 2.0 has a 4.4 V operating voltage. Atari onboard nicely informs about a damaged candle and its location. Just talk to him. Check the fuel topic by the way. For me, despite the 28st blockade, the fuel thickened in the pipes under the audiczka, burned what was in the filter and stood up. Wiocha was merciless, like a cordless Cordoba, I was pulling such a nanny. Half a day of warming up, venting and gone.

Hello
As for the hmm fuel, you can take this into account although I will add that exactly a month ago I replaced all filters and the fuel was refueled with the best fuel that is probably v-power at the same station as always. The car, of course, I was able to light the candles are OK, the computer failed to indicate any. I bet on a weak battery because it is already 8 years old

weak starting current, lack of starter dynamics and hence this problem. But that's just my guess. Maybe someone else will add something in the subject, and I would read more about PWM, if someone would recommend something sensible it would be a fairy tale
