Wood chips in diesel filter - TPI?

Hello everyone,

Does anyone know of a TPI (Technical Product Information) that justifies the presence of metal shavings in a diesel filter?

Hello...

Not good... the cam lobe in the CR pump must have failed.
Similar to the (some) 3.0 TDI engines...

If someone doesn't cover the cost of this disaster, it will be VERY expensive!

Have you ever accidentally put the wrong fuel in your car?

The shavings are usually everywhere, in the tank, in the rail, in the injectors... so everything needs to be replaced.

Hi,

Have you ever considered that they might come from the gear pumps in the gas station pumps?

I once observed this with canisters used to transport diesel fuel from the gas station.

AAAAAAAAAAAAAAAA

Now I see these DIESEL filters.

My brain had always read "DIESEL PARTICULATE FILTER" and wondered how on earth he managed to get there and why someone would look there first.

"Contamination at the gas station (and its supply chain) sounds like a fitting description to me."

.... which, from a business perspective, would justify replacing the entire vehicle instead of repairing it.

But does anyone know anything about TPIs in this area? I had read about it in another forum and was surprised.

Hello...

If that were the case, the pump at the gas station probably wouldn't be working for much longer! (With such a high level of wear and tear.)
Furthermore, it's likely that lightning strikes people who happen to be at a gas station at that particular moment.

for reference:

"The 'noble lads' are sometimes quite difficult to read, but they unfortunately fit the topic perfectly."

Sure. Please provide the text you would like me to translate from German to English.

The term "chips" itself is somewhat unclear. Are there any images and material data available for these chips? And what about the internal workings of a pump that has been identified as the cause?
Wear and tear would be more understandable in the case of a pump.
Were perhaps poorly manufactured fuel filters installed?

It's not as unlikely as it seems. "On various Volkswagen TDI models, metal shavings have occasionally been observed shimmering in the fuel tank when illuminated."
They were so large that they wouldn't have fit through the OUT screw of the VE (vehicle).

Hello!
Today, I'm doing my second Difi filter change, about 70,000 km after my first one. Last time, I had clear metal shavings in the filter housing. This time, there are absolutely no shavings in the housing. So, those shavings probably came from outside last time. The filter itself was anthracite-colored, and there was a slightly reddish coating on the plastic lid, which looked almost like rust particles (perhaps from the fuel tanks at gas stations?!).

What caused a few problems this time was bleeding the system.
The fuel level was just above 1/4.
Using VCDS, I first tried the "initialization" function, specifically the "first fill" option, but it was not accepted.
Then, during the actuator diagnosis, the fuel pump in the tank and the auxiliary fuel pump were alternately activated. Nevertheless, the engine only started after about 30 seconds of sputtering. What could I have done differently?

Hi!
Installed the third filter yesterday. Mileage: 190,000 km. No wood shavings present. The filter color is anthracite, with a very slight reddish tint on top, as described previously.

I performed the bleeding process as I did last time, but this time I pre-filled the filter housing with approximately 0.3 liters of fresh diesel. It then started up completely uneventfully after the pump was activated.
The correct combination seems to be pre-filling plus pump activation controlled via VCDS.

Thank you for the feedback!
So, you haven't repaired anything other than replacing the diesel filter each time?
I still don't understand where the wood shavings came from.

Best regards, Rainer.

Exactly. It's working perfectly and without any errors. I suspect the shavings actually came from the fuel storage tank, or (more unlikely) the manufacturing process.

Hello Bretzelmann,

After I once had a new fuel filter with a hole in it (and the worm that had eaten the hole was even still inside), I now examine all the filters very carefully before I install them. The filter with the hole was even a "part that had been tested for use in aviation".

Best regards.
