Same here, with my previous V60 - took them 3 attempts to diagnose a duff DPF pressure sensor as they don't have a directly related fault code.

How did you get on with Volvo Germany ? I found them to be somewhat indifferent with a UK registered car. Not interested though your car is still under manufacturers warranty.

They didn't want to know when I had a complaint with my out of warranty Volvo which was totally bu99ered brakes wise by one of their approved dealers.

Volvo HQ didn't want to know and Volvo UK had nothing to do with it as it was a main dealer in Germany who screwed up the rear brakes of my S60.

The moral for me is never trust a main dealer out of your home market when the vehicle is out of warranty. They couldn't give a stuff. New car rates under the arches service.

If the V40 D2 was an auto, then I would possibly be able to compare them.

Volvo Germany?
No complaints. They were very helpful. They highlighted a suspect oxygen sensor and when I told them that I thought it had been changed before, they went into the system and found it had been replaced in September 2014.
They even allowed me into the workshop.

My friend has a V40 D2 CC lux. It's a lovely car but very underpowered for me.

It's only a 1.6 engine.

Yes, I thought it was slightly underpowered, but not being used to a manual box, I was not sure.

Got my car back this afternoon.
Work done: Oxygen sensors cleaned, regen to DPF and the latest software applied.
Last software update was in June.

Am I convinced this is the end of my problems?
I live in hope, but no.

I hope you have better luck this time. You definitely deserve it.

I've driven it in D2 DSG and D3 Geartronic.

It doesn't feel underpowered with the DSG gearbox at all. I struggle to justify even the D3 version which has more power than is of use really. I was rarely able to give it full throttle. However the Geartronic is a bit smoother than the DSG I think. Would I buy the D4? Yes, but my wife won't be persuaded!

Well, I started this thread, and 9 months and about 9,000 miles since I had the uprated EGR cooler and valve fitted, I got the Check Engine light again today. No detectable difference in performance or economy.

Called the dealer, and interestingly, my car is probably going to be used as a guinea pig to try and resolve the EGR issue.

The dealer mentioned that a technical team from Volvo Sweden is coming over in early November and they are asking dealers to earmark several D4-engined cars that have already been fitted with the revised EGR & cooler as per factory instructions, and that have since had the CEL light recur.

The technical guys then plan to drive the car for a couple of days and do live datalogging to see what's actually happening in real-world conditions to the various EGR duty cycles etc, in an attempt to understand why the problem keeps happening.

Now, an optimist would say that they're really taking steps to iron out the problems once and for all. In contrast, a cynic might interpret it as a sign that they actually don't know why the EGR problems keep occurring, and that this sort of testing should've really been done two years ago.

I'm an optimist, of course I'll update with further news when I have it.

If you watched Building Cars Live on the BBC you'll know that the car design testing nowadays relies an awful lot on computer simulations and monitored indoor tests in controlled conditions. With the ever changing emission regulations I don't think the car companies have the time to do prolonged testing in all countries. I'm sure they will have tested the EGR to the best of their ability. I'm just totally in awe of all car manufacturers after seeing that program. Car engineering is way beyond good nowadays.

Hence the specialist team from Volvo to find out why this problem is arising in the UK with a number of cars.

They had an IT specialist work here last spring at Charlwood Volvo to resolve the bugs in the 2015 VIDA software.

Never make the mistake of thinking Volvo don't care about their cars or the quality of their engineering.

I agree to an extent, and I'm glad that Volvo is being active on this. It must be costing them a fair bit in warranty work.

However, Volvo did make a great play in the press and elsewhere of betting its future on the VEA engine. So I do find it surprising that a fault which has occurred (and is now recurring) so early in the service life of what must be a fairly significant percentage of the cars fitted with the D4 motor, wasn't picked up in pre-production testing.
