Out of the frying pan into the fire then. Previous Discos are renowned for EGR issues. And that's with the much lower Euro 5 Nox limit. Costs about £700 to fix at the main dealers.

It only needs a few of them to take the affected D4 engines off the lists and sales will be affected.

The problem effects every VEA engine from D2 to D5 so basically every diesel engine that volvo now fit to there cars,

There is a fix on its way but due to parts production there is a delay in its release,

Production line cars get the fix first then it is getting released to dealers,

From what we were told volvo have been working really hard on a fix but the EGR cooler clogging seems to be more of an issue in the uk that other countries and volvo have been in the uk testing fixes,

I would go with the Hyundai out of that pair.

Have there been EGR issues with the XC90 D5 VEA ?

2 cases apparently altho there was an engine issue with one of them from what we were told,

The xc90's are a bigger heavier car with a 4wd system and tend to warm up the engine quicker than the rest of the cars and it is the egr valve and cooler temprature that is the main issue as it doesn't get any warm coolant until the thermostat opens and its the condensation build up inside the cooler that is causing them to block,

The rework involves altering the cooling system pipework so that the supply to the cooler bypasses the thermostat so it gets warmer quicker

sounds quite logical , but its obvious with this and other types of fault on recent cars that they no longer properly test the prototypes these days .. They used to go to the sahara desert and North pole doing 100's of 1000's of miles before the car was launched .. I bet they stick them in a room and let a computer do it now . Do they do flat out testing at 150 mph all day long around Millbrook like Bentley do ( or did ! ) ? no the engine wouldn't take it now like they used to . Do they do Testing at the other extreme at Millbrook on the inner bowl doing 30 mph stop and cold starts all day long for days like lotus did with the Elise ? no i bet they don't ...If they did they wouldnt have had this EGR problem . you have massive multi million pound correction bills unless you do it properly , I guess that's factored in as being cheaper ! Volvo learned too many of fords bad habits and carried on with them after 2010 in my opinion . Where are all the Volvo factory engineers from 17 years ago , the ones who developed the XC90 and those before it ? Not a lot went wrong with the xc90 until about 2009 when a batch of problems arose !

TBH, my current 2014 XC60 VEA D4 has been much more reliable in the first two years of ownership than my 2006 D5 XC90. The rear wheel bearings started whining on my XC90 at 23k, the seatbelt clutch mechanism was clicking in my ear when we stopped and my chest moved under breathing and I recall that we had issues with the parking sensors too. We loved our XC90 but she was an expensive girl to fall in love with. It got progressively worse each year (bar one) until we parted company. So, on balance, our XC60 has only had the one issue, albeit reoccurring, and it's been the pet turtle / warning lamp. I think the XC60 has proved a much more reliable car than the first generation XC90, IMHO.

I appreciate that's based upon a sample size of just one XC90 so is hardly reliable, compelling evidence from which to draw any extensive trends. But my bank account certainly took a hit for Volvo and the local dealership.

PS. It sounds as if a proper attempt at a permanent fix is almost with us, but it'll take a long time for the dealers to work through all the VEA cars and I doubt it will be a recall - so I suspect they'll be given the proper remedy as and when they fail?

Land Rover decided it was the warm air that was the problem and did the opposite and removed the cooling system from their EGR's.

Volvo have made 12,274 new XC90's so far this year so 2 with a problem is hardly in the same league as the D4 Egr issue. They have made 19.679 XC60's so far this year for comparison. The V60 CC stats are 2,449 since launch.

[Rooster]

Well 2017m/y diesel volvo's will have the addition of adblue so looks like they may be changing the amount of egr the VEA engines use again,

Altho i think its spa platform only

[volvorocks]

So is that kind of Volvos way of saying 'the current egr set up is unfixable'..??
