Durable PDEs: Longevity and Reliability

Hi there,
Apparently, the particulate filter (DPF) elements in cars like Golfs and similar models are said to need replacement after around 150,000 kilometers due to wear and tear.

'But I can't recall seeing a similar case discussed in this Lupo 3L forum.'
Could it be that the particulate diesel filter (DPF) in the 3-liter engine lasts longer due to its lower consumption?

theory:
The wear actually occurs due to the removal of material from the tiny holes.
That would mean that it's not the mileage (km) but the total amount of fuel consumed that is responsible for tire wear.

Sure, here is the translation of the text from German to English:

'Beispiel:' translates to 'Example:' in English.
Cars like the Golf and Passat consume roughly twice as much fuel as a Lupo 3L.
Therefore, the total throughput should be half as much with the 3L version, which would mean double the lifespan.
Since we only have 3 cylinders instead of 4, the power output must be only 3/4 of what it would be with 4 cylinders.
That would be approximately 225,000 kilometers, roughly speaking.

There are no known cases of zygomatic complex fracture migration.
I think that because the 3L engine has an aluminum block and head, there are fewer stresses on the head gasket, which significantly increases its durability. Is that correct?
greetings

Hello,

I think you're making a mistake in your thinking.

Let's assume that...

Quote:

... the total amount of fuel responsible for wear

.

Then you still have the same amount of fuel per nozzle as with a 4-cylinder engine, but simply about the power output of one cylinder less.

The amount of fuel that a common rail injector needs to deliver shouldn't differ significantly between a 3L Lupo and a 100hp PD TDI engine.

Similarly, the proportionality between the weights of the two vehicles is still maintained. Install the 3L engine in a Golf and be amazed by the fuel consumption that is also possible with it .

I think that someone who buys a 3L Lupo probably doesn't really have gasoline in their blood and turns the country road into the Nürburgring .

Best regards,
Thomas.

Okay, our test TDIs with common rail injection have now easily exceeded 280,000 km, and nothing has gone wrong so far...and people really drive them hard.

Hello,

I find that impressive. It seems to be a solid engine.
I assume these are also 3L Lupos?

Greetings,
Thomas.

What are the engine codes for these TDI tests?

Okay, so we have a 3L Lupo with only 243,000 kilometers on the clock... MKB???

Okay, here's the translation:

'Then we have a Golf IV Estate with 230,000 km, manufactured in August 2000, engine code AJM... and then two Passat Estates (December 2000) with approximately 280,000 km, engine code ASZ (130 hp PD).'

Both Passats have already had new clutches installed, and one of them received a new turbocharger. The Lupo often experienced problems with the automatic transmission and starting issues (due to the start-stop system).

But as I said... they still have the original PD components.

Okay, no problems with the AJM, I actually have one myself.

I read on the Passat forum that at around 180,000 km, the bushings in the trapezoidal connecting rod can wear out, which then causes a knocking sound similar to what you hear with faulty hydraulic lifters.
