D4 VEA 'check engine' light / EGR fault thread

Clan, re the continuous software updating, I don't quite get it ?

if everything is running well as designed with no problems, why update the software continuously ? and surely constantly changing the software could introduce problems that were not there before ?

is it just a ploy to get owners to use only dealers for servicing ?

If you saw the lines of communication between the dozens of control modules you would be astounded , it's an incredibly complex network system . But that is the designers problem , we can't possibly understand it all together in the car .
99% of it runs as designed of course , but fine tuning is found to be needed to cure some minor undiscovered issues . Interaction unaccounted for in the design may be found later . The safety system is added to as time goes by as fresh accident data comes in , they may alter timings etc .
the emission EGR system has been tweaked a lot to get the cooler and valve working as designed .

Yes only dealers can sort the majority of problems out as they are the only ones with factory training , test equipment and back up , no one else can do anything as they are not trained on the specific systems . The only specialist here is the dealer .
The new xc 90 has been remarkably reliable mechanically , but the software has cured most of the small niggles and problems , that is one of the advantages of an electronic computer controlled car .
the same goes for anything these days .

thanks for the reply and info Clan, maybe I'm just a wee bit cynical ?

Hi I have a v60 2014 now well out of warranty with 95000 Miles last week I had a small water loss for the first time ever and now today the dreaded warning light
It has never had any egr issues is this likely to be the dreaded and do you think Volvo will still cover this as it has a full Volvo history
Any comments would be greatly received

yes it is possible there maybe still help available on the EGR system , but you need to let them see what the problem is first , and advise you ...

You've done well to get it to last that long.

However, the EGR issue isn't usually associated with water loss, so it may be that you have a different problem or two problems at once!

Almost 3 months of trouble-free miles and then the dreaded light came on again, followed by the tantrum from the Mrs about why oh why did you buy this blo**dy car and so on...

Back to our local maindealer who reports ECM-PO14C00-02 O2 sensor requires clean. They have removed, cleaned and refitted. Also upgraded ECM software. I don't which version of software it was on previously, nor now, but it would be interesting to know if forum members have found if any particular version is the best.

I hope this is the permanent fix (as I was assured it was last time), what will be next after a dirty O2 sensor I wonder

The latest is always the best version , you have no choice in which software goes in it is always the latest , your latest software contains a fix for the dirty lambda sensor , it has not been out long .

Sorry to dig up an old thread but I’m potentially going to buy a used d4 and don’t like the look of this.

Have they fixed it? Can I do short journeys, 5 miles?

Can the egr be blanked?

yes just about fixed it now , 5miles will be ok as long as you get out for longer journeys once a week I would say . There is probably still help available from volvo even if it is out of warranty , get your nearest dealer to check its egr history . A good sign is the top radiator hose , If it has a big T piece half way along it , It means it will certainly need further work at a later date .

No you cant blank the egr ! This was the worlds most advanced diesel 3 years ago .
