Many thanks.

Nevertheless this video is related with the petrol engine, with several issues in the US.
Concerning the diesel engines (2.0 VEA), there are people complaining, but nobody is giving the final conclusion or even the solution for the issue.
It is a mechanical issue, i mean, piston rings and even the pistons?
Or it is a software issue?

A new design of piston and ring was fitted from the middle of 2016 ...

Interesting they seem to have switched to a more traditional looking oil control ring. I guess us old farts knew what we were doing after all!

If I have understood correctly, the fix that my local Volvo specialist has adopted is to recondition the cylinder head (because the valve stem oil seals often become hard) and to replace the pistons, piston rings, and crankshaft bearing shells. In short, a partial engine rebuild.

He has advised that this has worked for his customers. Not cheap, however....

Many thanks for your answer. It is almost an engine rebuild.
In my opinion does not make sense in cars with less than 10 years and less than 200k quilometres.

If a person's car has the oil consumption issue then they need to work out the cost of repair and compare it with the true cost of replacement.

Repair will be a cost but it will add no resale value to the car. If, however, the car is in good condition in all other respects then the repair will add value in terms of what the car is worth to the owner.

Replacement depends upon what the replacement car is, how much it cost, what it will be worth to the owner, how much maintenance it will need, the cost of depreciation, what profit the seller made etc. A complex calculation.

For most brands the decision is probably a no-brainer, but Volvos are a bit different. I bought my first Volvo in 2011. It was a 1998 V70, i.e. 13 years old but a lovely car. That car is still on the road in 2022. You won't find many 1998 BMWs, Mercedes, Audis or Fords on the road, however.

There is another way to see this, as Volvocano linked a video showing the problem and it's suggested to get the car hot and keep the rpm up to 3000 for 5 minutes to decoke the rings,

However having had a Passat 2.0 PD in the past that thought oil was tasty that used enough oil in 250 miles to chuck the warning light on even though it had been serviced the day before, upon checking the manual mine wasn't even close to what VW said is acceptable so although it's a bug bear to have to top it up a couple of times a year I wouldn't let it bother me, the Pishat would use at least 2L per oil drop which was 10k, always passed it's MOT didn't have a DPF and as much as I like some of the VAG range across the brands I wouldn't want another one as I felt after 2007 the whole ethos of the brand changed from reliable and tough to flimsy and weak.

Did I miss something? Who suggested this?

The guy who made the video suggests it in his comment to one of the comments on the video,

The idea is like a dpf cleanse, you get things hot enough to turn the carbon into ash and then it should scrape into the sump and hopefully get caught in the filter.

0.5 litre every 2500km/1500 miles ain't too bad! My redblock with 168,000 miles eats 1 litre every 1000 miles, although it runs like a top.

I heard on a youube video that VW's acceptable oil consumption is 1 litre every 1200 miles, and I think they have updated the piston design on their 'problem' engine. I imagine Volvo has a similar acceptable limit.
