Engine Power Loss: Check Spark Plug Coil

Hello! Unfortunately, I haven't found a suitable topic for my problem .

My problem: About a week ago, my Skoda Octavia 1.9 TDI, manufactured in 1997 with 66 kW, suddenly started to jerk. A few days later, the power dropped as if the turbo was defective (limp mode?), and the check engine light comes on intermittently. After restarting the car, the problem is temporarily resolved for about a minute, then it reappears.
When the engine was cold, there were no problems, but when it reached operating temperature, it started to misfire, with a loss of power, and the glow plug indicator light came on.

What could that be... Please help.... KYLIE

HI.

Your car is trying to tell you something (the glow plug is blinking).

Now, you just need to ask the right question: So, either read the error codes yourself or have someone else read them for you.

Otherwise, all we can say is:
It seems something is broken.

Sorry, but that's just the way it is with those computer-controlled engines called TDI.

Very helpful, thank you!

Two error codes were found and deleted during the reading process.

The mechanic said something about the 'needle'... something (I'm sorry, I didn't catch the rest).
broken, approximately €300 exchange.

Any other ideas?

If your mechanic tells you that your car has indicated a problem with the throttle position sensor (that's the part whose name you always forget), then I would trust the mechanic. We're usually not in this profession to sell unnecessary things (if we were, we'd work at ATU... but even there, some people can operate a diagnostic tool).
So, you'll be left with no other option than to bite the bullet and have the faulty part replaced. You'll see, it's almost like magic: the yellow light will stop blinking, the jerking will stop, and your car will have its power back. It will have returned from the emergency mode it's currently in.
BTW... 'stuttering' + light bulb... a reasonably skilled professional would only need the tester to confirm their suspicion; the NBF cannot be more clearly defective.

Best regards,
Dominique.

More specific error codes would be helpful. As soon as the indicator light starts blinking again, there must be at least one error present. Therefore, to be absolutely sure, check again and write it down. However, "NBF" (No Boot Found) is already extremely likely.

Point 4 and 13.

Have you read this yet?

If you had read the technical articles thoroughly, you would know what's causing it when someone talks about the needle......something . And you would also know how to check if it's due to that before replacing it, which can be expensive .

And always be polite, because we are, after all, answering your questions for free and in our free time .

'I'm just looking for a second opinion from unbiased experts to confirm whether my problem is actually caused by that. I've already been told by a reputable workshop that it's the mass airflow sensor (MAF), but I want to be sure.'

Okay, let's say it's the needle lifter mechanism. Is there a way to repair or verschandeln it? Are there any known solutions or experiences with this?

Thank you, Kyl! E

Hello Kylie,

You can check the needle lifter yourself!

A note about the search function: it also works with word fragments . A search for "needle" yields a thread titled "Needle distributor" https://community.dieselschrauber.org/en/viewtopic.php?t=4624&highlight=nadel.

The search query "defective needle lifter" has higher accuracy, among other things https://community.dieselschrauber.org/en/viewtopic.php?t=1028.

After that, you can check whether the workshop and the people here in the forum have any knowledge .

I haven't heard of anyone successfully repairing a needle valve actuator yet.

Best regards, Karsten.

Edit:
I was in the middle of answering a colleague when the fog machine was faster...

Thank you very much for your advice! I'm going to try it right away...
