High Oil Consumption Linked to EGR Cooler and Valve Issues?

[Sotosound]

To try to answer one of your questions, the oil consumption issue can be solved in many cases by a partial rebuild of the engine, with new pistons and rings plus a reconditioned cylinder head.

Not cheap, and it also assumes that the issue is caused by blocked oil control rings and knackered valve stem oil seals.

Sorry.

Fun is different, it's not an 'R' Design, but in my time I've done ten ton, 0 - 600 in 40 seconds and 8g, so internal pollution of piston rings chiefly. How do the different driving modes affect the quality of and cleanliness of combustion?
And is there a recommended oil flush or treatment that can de-gunk oil control rings or is it time to give up and call it a day with this car?

Volvo Sheffield said Volvo UK refused any goodwill on my D4. "Computer sez no."
Should have kept my 5cyl D3. The engine was running sweet as a nut at 150k miles. It also had a number plate that somehow confounded ANPR cameras.

It's a difficult situation that you're caught in and I'm sorry that it's so. There's also no easy way out that doesn't cost real money, either in repair costs or in money spent on trading in for a different car.

If the cause is oil seals and piston rings then the repair option has its attractions provided that the rest of the car is sound. The engine will have had its life extended and also the replacement pistons rings should be of a new design that's less prone to getting blocked. Even more than this, your D4 is ULEZ-compliant and only costs £30 annually for Road Tax.

A trade-in for a younger vehicle with a warranty would, in theory, represent a quick extrication from the issues, but used car prices are very high right now and I'm not sure whether or not the V70 was ever built with the revised pistons and rings.

Firstly, however, you do need to establish exactly what the cause or causes of your issues are, and that will also cost money. And while the car has issues it's not really saleable either.

Quite depressing, and a bit like life in December 2021, really.

If your smart enough to conclude that the dealer only fixes their wallets
Why bringing your out of warranty car there?
They are expensive ,always the "official (expensive)protocols"
Its an horrible bureaucratic "authority that is praised by the volvo cult also on this forum (not all but many) and not to be questioned
Try to fix it yourself ,there are many sources and hobbyist with instruction clips on youtube to help you.
If you cant or want do it yourself...seek out an independent garage without the marble floors and suits (where you pay for) and good credentials

Thats a bitmof a sweeping statement. Not all are that way.

Ive found a dealer that has proven superb across the life of 3 x XC90's, and seen them past a combined 500+ k miles without a single breakdown beyond bulbs. 2 year guarantee on all work, which is double or quadruple that which most indies will give, and all parts have a lifetime warranty.

They've faltered occasionally, no one is perfect, but have always entered into sensbile discussions and provided an effective and timely resolution. Twice I've been given a free service worth 300 quid by way of an apolofy for a minor issue.

Conversely, there are plenty of threads on this forum about people who've taken their steeds to an independent, paid hand over fist, and then ended up having to take it to a dealer to resolve the problem anyway.

My nearest 'reputable' independent, often lauded on this forum, is 40 miles away, and I've since found out that they farm a lot of work out to local specialists anyway, so where is the incentive to jump ship to them?

A sheet garage is a sheet garage regardless of what it says over the door.

The OP needs to find a good garage that will identify and repair the fault, not merely keep addressing the symptoms. The nature of their business structure is utterly irrelevant if they are good at what they do, and im sure the OP won't care what overalls they wear or how shiny the floor in their ateium provided they can do the job.

It is relevant.... if the business structure is focused on sales ,suits and marble floors then its not focused on old fashioned diagnosing but on selling overpriced parts and man hours (and the marble floors and suits ofcourse ) it has to go from the wallet and work quality in the end
Just replacing everything because computer says so aint work quality

But they sell the volvo cult and if you want to buy that ....your free to do so

Most of the small repair garages go unfortunately out of business as they are unable to keep up with the "digitalized cars" we are using now and which will even increase in numbers in the years to come. Not much we can do about it, but very regrettable indeed. I have maintained my cars myself the last 40 years, but I am about to throw the towel as well for all problems engine related. I can't afford to buy all the sensors needed for trial and error diagnosis.

The big brand dealers over here have no other possibility than to follow car makers instructions with regard to buildings, marble floors, show rooms, and the tie wearing staff. They either follow or loose the dealership. But all this fancy stuff has to be financed by the customers of course. So I understand your reasoning. I try to avoid them as the plague or Corona for that matter, but sometimes there's no other choice.

So you guys have agreed that dealers can be an issue.

What is really needed now, however, is good practical advice for AlienInThisWorld in terms of what he can do other than to distrust Volvo dealers.

Are you able to assist?

Distrusting the dealers is the begin of his journey to a solution. There are specialists that do the piston ring replacement
