Horrible solution for intake manifold/EGR soot recall "fix"

[mattjeu]

Hi All,

In 2019, we had 2 (even 3 or 4) recalls for the 2014 V60 D4 cars, the one's I am most angry about are the EGR / intake manifold carbon buildup recalls. Volvo delivered the 4-cil D4202T5 and other diesel engines in the V60 diesels in 2014 and later. So much gunk could build up in the EGR system including the air intake manifold, that it could actually catch fire.
Instead of really fixing the issue, they decided to do a "software update" that warns users when your car is about to catch fire. (simply said)

This is what I learned from reading about it on several posts and the recall descriptions itself.

So, if you have an engine with this EGR circuit, it's supposed to be Euro-6. however since this and last year, several european countries started with particle filter measuring of diesels, causing thousands of diesels to fail and not pass the yearly check.
Some of those have removed the DPF filter but many are unsuspecting customers like me, who paid thousands of euro's over the lifespan of the car on maintenance and parts.

Looking with wide open eyes at the youtube video's on cleaning this EGR system and the intake manifold, I am wondering how a company like Volvo would willingly allow their customers to destroy their engines with carbon buildup where "clean" air should be.
Of course the emission is affected by this carbon and soot on the intake. and of course your oil will get dirty and clog the piston rings. It will also destroy your DPF filter much sooner then needed. Why not do the right thing and periodically clean this gunk off?

I am paying 80 euro for a crappy interior filter but my engine is destroying itself with crap from the exhaust and nothing is cleaned?

Is anybody suing Volvo for this? can they really get away with a crappy fix for this serious recall? I will ask for Volvo to do the right thing and not let me pay full price for cleaning something that they designed..
No Volvo diesel with EGR like this will reach 300.000 without falling apart I think..

Sorry its my first post but after my car failing the emissions test I started reading and my love and respect for Volvo has plummeted. I could say goodbye forever and spread the story about how a "quality" brand like Volvo destroys the environment not by emissions but by destroying their own product prematurely causing more cars needing to be build and sold. great...

What about the engines that have reached 300k miles and didn't fall apart?

I guess betting red or black in a casino makes a good comparison.. At least looking at some of the news articles;

https://lenews.ch/2023/03/24/new-pol...f-swiss-roads/

(many more in Dutch/Belgian/German language)

At least the parts needed (sometimes a new DPF filter is all you need) are also not available.. many have severe shortages in demand vs supply.

I think you missed my point.

Exaggeration and misrepresentation is pointless, no matter how unhappy you may be.

Your 300,000 mile comment served no purpose and is apocryphal, so why bother?

And the other issue is that EGR reduces NOx, quite considerably when working properly. Particulate filters are exactly as the name describes. You could disconnect the EGR or even blank it off entirely and it will not cause a car to fail a particulate or smoke opacity test. In terms of function and effect they are unrelated systems.

And the mechanism behind piston ring gumming is a third matter entirely.

I do not doubt that you have problems, but you're attributing cause and effect in the wrong places.

What would be your attributions?

Doesn't strike me as something specific to Volvo - Manufacturers had to fit this tech to meet the standards, and anything with EGR is going to fill itself up with soot, thats just the way it is.


If you are going to clean it out, make sure you wear some nitrile gloves. Some of the particles are so small, trans-dermal absorption is a possibility
