That's already something. I used to have a problem with the windshield freezing up after a short drive, especially after I had just scraped it, but now that I have a heated seat, that doesn't happen anymore.

"Does it make sense to run the engine while scraping ice off the windshield? It certainly does for a gasoline-powered car."

The politicians who criminalize and condemn such things probably all have a garage or are driven around by chauffeurs.

Well, I still don't have a real comparison, and I also have a garage.
Therefore, I cannot say how long it takes for a candle heater motor (in comparison) to defrost the windshield or prevent it from fogging up again .

However, since the candles are located in the water outlet leading to the heating heat exchanger, the interior space benefits from their heat output first.

It's also unfortunate that the glow plug system is under such high load during the afterglow phase, to the point where, for example, my AFN (in low light) only activated one or, at best, two of the three glow plugs. At moments like those, many "lantern parkers" (with corresponding detailed knowledge) would probably wish for a switch to turn off the glow plugs .

Hello.

I would best describe the heating power of the glow plugs in the coolant as being similar to the heating power of a 12V fan heater. You can plug these devices into the cigarette lighter socket, and with a current draw of 10A, they produce about 120W of heating power. The glow plugs produce lukewarm water in the coolant, and the fan heater creates a slightly warm breeze inside the cabin. In both cases, you can hardly speak of real heating power – they are auxiliary devices to supplement the poor heating performance in diesel engines.

I just want to point out that most people want to have heat as quickly as possible.
Most people crank the fan up to full speed, which means very little heat comes out and it takes even longer for the engine to warm up! *Shiver* *Clatter* The best and most effective way is to set the fan to level 1, so the engine warms up faster and you get noticeably more heat! Only use level 2 when it's warmer than lukewarm.
That's just the best way to do it with my Golf and Bulli!

With Climatronic, even when the engine is cold, it usually starts on a low setting, but then automatically adjusts to a higher setting as it warms up.

How are the glow plugs controlled? Specifically, at what outside temperature do they activate (for a 1.9 AFN engine in an Audi A4 from 1997)?
How can I test the spark plugs to see if they are still working?
And where exactly do they sit...?

Sure, here's the translation:

'Thank you.'

I don't really understand why people are complaining that the diesel heater has poor heating performance...
That's actually the advantage!
He just has a better efficiency and doesn't waste the fuel by turning it into hot air.
"With the 1z/AFN engine, I don't find the glow plugs to be that important because it warms up relatively quickly. It's different with the V6 TDI engine. That one takes forever to reach operating temperature, if it ever does. My brother has one in his A6, and at low temperatures, it takes about 7-8 kilometers before the needle even moves. Mine reaches 90°C much faster."

Gasoline engines pay for their heat with a good amount of gasoline consumption...
