Alle 4 Glühkrzen defekt? | Posts 16+

Hello.

Today, I successfully replaced all four spark plugs with four new BERU plugs. It went smoothly. The day before, I sprayed everything around the spark plug wells with rust remover and warmed up the car before the replacement. All four candles were completely covered in soot, as can be seen in the picture from dieselmartin.

I would like to thank you again for the numerous tips.


Best regards.
Peter.

"My friend's Passat AFN was making a grinding noise . Even at -12 degrees Celsius, it would start after a few attempts, but with a bit of smoke, despite having 4 faulty glow plugs . You wouldn't notice anything unusual when the temperatures were warmer, even though the glow plugs had been defective for a long time . Later, I tried using Spasshalsbar (a product name) at -5 degrees Celsius and disconnecting the glow plug relay, and it started perfectly, just to rule out coincidence ." It's probably got really good compression despite having 180,000 km. I'll try testing it on my Bulli sometime when it gets really cold!

Hi!

Since I used to work a lot with the older VW diesel engines,
I bought myself a measuring device with a clamp meter.
That goes up to 1000 amps.
This can be used to reliably determine whether and how many glow plugs are defective.
