Oil consumption A6 3.0l DDVB

The A6 currently has less than 20,000 km on the odometer. Within a distance of approximately 8,000 km, the oil level has decreased by about 80%. According to the car dealership, an oil consumption of 0.5 liters per 1,000 km is within the manufacturer's tolerance.

The car dealership initially only performed a visual inspection for leaks, which revealed negative findings. The car is still under warranty. I feel like the oil consumption is too high for me.

Are there any particular anomalies or unusual characteristics associated with this engine?

Are you referring to the range between the minimum and maximum levels on the display? The difference will likely not exceed 1.5 liters, even with the V6 engine. Consumption is approximately 1 liter per 8000 kilometers.

For me, it's completely within the normal range, but it might be because I got used to dealing with oil consumption of up to 1 liter per 1000 km almost 40 years ago, according to the limit. At that time, the VAG group's specification was 1.5 liters per 1000 kilometers.

Back then, BMWs (especially those from the 02 series) were often nicknamed "BMÖl" because of the typical blue smoke they emitted.

I taught my daughter, at her swimming lessons, to immediately tell the instructor if she starts to feel uncomfortable or if she needs to stop.

Okay. Audi states that the difference between the minimum and maximum should be 1 liter. We'll see, because my brother-in-law now has to document the consumption.

I know the consumption isn't dramatic. However, I still find it too high for a new and modern car. His old A6 3.0 TDI with 330,000 km has consumed less oil.

Can anyone tell me which Shell Helix Ultra oil is used by Audi? It must be ensured that an identical oil is used for topping up.

Unfortunately, the car dealership is not able to .

The answer is simply:

You can use the following oils for your vehicle:


Shell Helix Ultra ECT C2 C3 SAE 0W-30 50400/50700

Shell Helix Ultra Professional AV-L SAE 0W-30, meeting specifications 50400/50700.

Hello Andreas,

The hybrid draft horse that your brother-in-law owns requires an engine oil with the manufacturer's approval VW 507 00.

According to the manufacturer, this is a long-life engine oil of the 3rd generation. Generation used. SAE 0W-30.

Filling capacity with filter: 6.10 L.

In the parts catalog, the oil can be found under part number.

G S55 545 D2

again.

Otherwise, this model occasionally has issues with the accurate display of the oil level.

See also TPI: 2040749/5 for further information.


An "low oil level" warning can appear even when the actual oil level is still approximately 25% above the minimum level.


If you add oil now, it could lead to overfilling.

If there is excessive oil overfilling, it can cause the oil level sensor to produce an incorrect reading, which may trigger an unwarranted "oil level too low" warning.


What does that mean for your brother-in-law?

If he really wants to make the effort to document the oil consumption, he will need a dipstick again. (It costs about 20.00 €).

The readings in VCDS fluctuate daily and do not provide 100% accurate information.


If it is not a leased vehicle, I can recommend a ceramic additive based on my experience.

Does that help you?

Best regards,

Michael.

What do you think about the saying "...keeping things as they are..."? The car dealership has no way of knowing exactly what information Audi entered into the manufacturing date field.
Either adhere to the specifications outlined in the operating manual when topping up (which is what I do), or drain all the oil and refill with new oil, plus purchase an extra amount so that the exact same oil is used for topping up. The best thing to do is then a motor flush .
The DDVB isn't really anything special.

Thank you for the information.

The Audi is not a leased vehicle, but it still has a warranty. Therefore, I suspect we should avoid using ceramic additives. Just out of curiosity: which one would you recommend?

How much effort is required to upgrade this measuring device?

And you're right, Herbert .

That wasn't entirely serious on my part. The "workhorse" in question is called the Audi A6 50 TDI Hybrid Quattro... That sounds like endless power... and in reality, the engine has significantly less power than the old biturbo. - Whatever.

Back to the topic:

The engine already has a tube for the dipstick that can be used to drain the engine oil. It is fitted with a tamper-evident seal.

There is no longer a dipstick that remains permanently in the engine.
The device is called a KD-Peilstab T40178 and is only used for temporary checks.

Since it's not a leased vehicle, I would follow Herbert's advice and do a proper oil change with an engine flush. After that, carefully fill the amount and observe.


Personally, I use Liqui Moly products, but I can't say whether they are better or worse than other brands.
I think the technical hotline and support are good.



Best regards,

Michael.

As of now, with approximately 32,000 km on the odometer, my brother-in-law has added 0.8 liters of oil twice within the last 21,000 km. According to the on-board computer display, i.e., without using a dipstick.

Perhaps this is the new contribution to environmental protection for a modern engine .

Just a note: He should ideally aim to change the oil every 15,000 km if he values his engine.

That is always advisable. However, this will only mitigate the wear and tear, because I still maintain that something is wrong with the engine.

Has anything fundamental been changed in this engine compared to its predecessors? Not that it will be like with AMG, where engine damage costing between 80,000 and 150,000 will occur, due to the high-strength Alusil coating on the cylinder walls.

It's perfectly normal for an engine to burn a certain amount of oil, as a 100% seal is not possible. However, a mechanic might be able to explain this in more detail...

Here's the translation:

"The fact is that there's always some amount of fuel, water, and soot entering the engine oil, which degrades the additives and accelerates wear. Consequently, every owner contributes to internal engine wear through the use of long-life oil."

"As a good example, I have the AFN engine in my neighbor's A4, which I maintain. It currently has approximately 675,000 kilometers on the odometer. I change the oil every 15,000 kilometers, and I've observed that it consumes almost no engine oil for the first 10,000 to 12,000 kilometers. However, in the last 10,000 kilometers, I have to add about half a liter. After the oil change, the consumption returns to zero."

I completely agree with you. Your statement has been valid since the invention of internal combustion engines. However, in my opinion, it cannot be the case that his old ASB (3-liter V6 TDI) with over 330,000 kilometers on the clock consumed significantly less oil than the new engine.

Therefore, I am particularly interested in whether anything was "improved in a way that made it worse" in the "construction/coating of the engine." The numerous plastic parts and the cost-cutting measures evident in the design and handling of the product are definitely not a good sign.

You can have two identical cars with identical engines, one that uses 0.00 liters of oil and another that uses 0.2 liters per 1000 km... and how are you supposed to explain that, other than by manufacturing tolerances?

Then, the ASB has a completely different type of fuel injection and, above all, exhaust gas treatment compared to the current engine.

The engine oil is subjected to much greater stress and, consequently, becomes more contaminated, which in turn leads to increased wear and tear, especially when the engine oil loses its original lubricating properties.

An oil analysis of both engines, based on their respective operating hours, could provide valuable insights.
