Stalling at low RPM (Golf 3 TDi Variant)

Golf III TDI 8/95 Variant (90PS series, with ***-Sportsline chip, approximately 110 PS)

I experience a 'jerking' sensation when the engine speed reaches around 2300 RPM.
For example, if I'm driving on the highway in 5th gear and I need to slow down to 100 km/h, and the engine is around 2000 RPM, I need to shift into 4th gear, otherwise it 'jerks'. This is especially noticeable when the engine is cold. Has anyone experienced this before, and what could be the cause?
And the shaking is very noticeable, as if he's choking or not getting enough diesel. Would be what an amateur would say!!

What can you say about it? Who else had the problem and does it still exist?

Is there a solution?

Get the error codes read:
Was was damit zu tun haben??

'01117 027'
Generator Terminal DF - Load Signal
unplausible signal
'Intermittent error'

Thank you already

Give "Ruckeln" and "1Z" with all words into the search function... I think you will only be overwhelmed with fellow sufferers (I was also involved...).

There is always a solution!
Since there are several possibilities for causing cavitation in a 1Z system, everything from the low-pressure relief valve (cheapest option) to the pump replacement (most expensive option) is possible.

The shaking you describe is almost exactly what I also had, and in my case, it lasted until the end, and only the ESP was still the old one.

I think this has nothing to do with the shaking.

Hello,

So, after I've looked around/read about it, it seems like it's probably 90% a problem with the needle driver. What does a replacement/repair cost?

I've just had another possible reason in mind. Specifically, I've had a chip installed about a year ago. It was from *** in Kempten. Is it possible that something has malfunctioned due to the chip after this period of time???
So, nur eine Vermutung, könnte ja sein, oder?

Hi,

For a 1Z, I can offer you an AT price of around 150 euros + Märchensteuer (price from the beginning of 2002 at the Bosch service).

However, the shaking you describe is atypical for the NHG. The NHG should suddenly switch to emergency mode or produce a very harsh shaking at high speeds. For the impossible, I don't hold.

Regarding the nozzles, I can only refer you to the following post:
/viewtopic.php?t=3697
Check the print. Depending on mileage, I would also replace all nozzles and not just the NHG.

The chip could enhance the effect, but not necessarily cause it. If it worked at the beginning, it should still work without any defects.

Hi,

Bitte geben Sie die Laufleistung [img] aus. Der Code 01117 ist auch regelmäßig im Fehlerspeicher vorhanden. [/img]I think the problem lies somewhere within the generator area (voltage regulator, connecting cables) (I'm ignoring it).

To reduce vibrations: If you have over 150,000 km, then replace the NHG. My friend's vibrations went down to 100 kmh after the replacement -> everything was fine afterwards. I can get the NHG for 127 euros at my parts dealer. On eBay, I once got one for 80 euros (new).

Hi,
My car also used to jerk. After I replaced the alternator regulator because of its worn-out brushes, the jerking stopped. But it could also have been a coincidence.

So, the mileage of my Golf is 220,000 km!

So, my 1-bedroom apartment at KM-Stand had a new NHG (heating system) installed around 70,000.

However, before that, there was more of a jerky movement, as Bertil described.

Best regards, D.

Caution: There are two different types of jolting at 1Z.

1. The hard misfires: (short engine misfires)
-> Causes either NHG or Relay 109

2. The Full-Load Trucking: (occurs only within a specific speed range, as if you are in the wrong gear)
-> Causes: Inability of the metering system, in my case, replacing only the pump helped, replacing the metering system would have been almost as expensive as replacing the entire pump.
However, when I disconnected the speed sensor on the transmission, the jerking stopped!

Hi,
My 1Z engine 'stutters' slightly when I'm in 5th gear. At speeds below 70 km/h (slightly above idle).
I wouldn't consider that a fault, however, at the operating speed.

However, it is one of the last 1Z models from '96, which already has the 16-bit ECU installed.
It seems that the flickering issues primarily occur in older 8-bit STG's.
or has anyone else had problems with a 1Z engine from '96 (021BF)?

Best regards, Rudi

Hi Rudi,

The 021BF was only installed sometime in the middle of the MJ. My earlier 1996 model with the 1Z engine had a ...021AF.
I vaguely remember a thread where someone was trying to eliminate the stuttering by changing the STG (I don't remember exactly what it was).

And where/how can I get it checked to determine the main problem or the cause?
What does it look like when the technicians say that the problem is due to the NHG (presumably a specific component or system), but after replacing it, there is no improvement? Do I still have to pay the full amount?

Oh, I also had one more thing in mind:

And that's when I started noticing the shaking (about 2 weeks prior). Initially, I thought it was just my imagination, but then I tested it and I was missing 10-15 km/h at the top, because 'there was no more power' there!
Can it also be related to the whole 'ruckel' problem and provide insights into what might be causing it??

Hi,

if I remember correctly, a faulty mass airflow sensor (MAF) can also cause jerking -> search function. You're going to have to perform a diagnostic scan with a VAG-COM, otherwise we'll be looking for a needle in a haystack.

And how should I do that without a VAG-COM??

Get soldering iron and build adapters (I managed it myself) and get a VAG-COM... once I've fixed something myself on the car, the investment costs will definitely be covered
