Gelöschter N. What error is your tester showing? What is the error code?
OpenAlexander W. That looks like a service light. Do an inspection and reset the service interval with a scan tool.
Bernd F. No, OPEL is a bit strange about that. I've had that before. After asking, I got the information that it was the display for errors. I don't remember what was wrong with mine, but after the repair and clearing the FC, everything was fine again. Have the error codes read out and then we'll see what happens.....
3Alexander W. Ah OK, thanks Bernd. With us, something like that always stands for upcoming inspections. 👍

OpenMarkus T. You're probably only resetting the oil reset with the diagnostic tool; maybe you have to reset the service separately. What kind of device do you have? Internet-based or a professional device?
Rabit Z. This error I send photo
Rabit Z. Unfortunately, it doesn't work. I've tried, but it doesn't work. I'm using OBD2, but I'm still getting it.
Alexander W. Write down the error better. The photo is unreadable
Rabit Z. Fault code is P0674. Glow plug control cylinder 4 malfunction
Lutterschmid C. I had the same problem once. In my case, however, it was the thermostat.
Rabit Z. Code error
Rabit Z. I have no idea, ömdc said there was this error, but I wanted to ask if this information is always correct because of this problem.
Alexander W. The error indicates that the glow plug or the cable to the glow plug is defective. Have the cable checked under load from the glow plug control unit/engine control unit to the glow plug.
However, I think your glow plug on the 4th cylinder is defective.
Replace it and it will work again.
Replace the other glow plugs as well. Then you will have peace of mind.
1Roland B. Replace all 4 glow plugs, then the problem is solved.....
Rabit Z. I also think better is thanks 👍
Marcel S. Glow plug, should I just replace the one!
Roland B. Always replace all 4 glow plugs, not just one
Rabit Z. Yes, my local Opel dealer said that only 1 is defective and the others don't need to be replaced.
Rabit Z. I sent photos and wrote down the errors. Thanks.
Marcel S. I also had to change cylinder 4, I have a pressure sensor, it costs 120€ each! For the version without a pressure sensor, I would like to replace all four because the price is very low

I did it, it worked. Thank you.
