Ran out of Ds for the title.

Any talk of diesels these days usual includes DMFs, injectors-this, DPFs and fuel pump-that. However, it's rare to see said faults when talk is of Volvo 5-cyl diesels. Do they suffer from the same problems that plague the diesels from seemingly every other make?

Don't these things usually cause more hassle in cars used for short trips, pootling round time? I believe DPFs etc need a bit of a good thrash every now and then...

We have a D5 XC90. 5yrs old, 75k miles or so and thus far it's been fine. But does get a good clear out (a bootful on long trips) now and then.

2008 D5 in S80, 152k miles now not a single issue at all with the engine although it has just developed a water leak on the sunroof . . .

If you have a DPF you need to spend 30-40 mins a week at 50+ mph on a dual carriageway so it can regenerate. Don't drive a diesel lightly either, they need a thrash now and again to keep them clean, at least once a week.

They do seem to be pretty robust, that stty swirl arm lever causing more trouble than the usual diesel suspects. You get the odd person with DPF problems, I wonder if the problems kapiteinlangzaam had with the sensors were caused by some sort of fuel contamination, or as suggested related to the intercooler fault. Certainly not common parts to fail on any car.

My C70 D5 manual needed a new clutch at 68K miles when I remapped it, but it was down to the spring becoming weak rather than plate wear and there was a batch of duff clutches in 2008. They measured the DMF for wear and it was absolutely fine, so I didn't replace it.

I wonder if the relative lack of DPF issues is because people are less likely to buy the large cars you find the D5 in for Miss Miggins half mile runs to the cat food shop like a smaller car? The technology and suppliers they use are exactly the same as everyone else uses, although I imagine their is all sorts of proprietary integration and calibration work that makes a big difference to the systems reliability.

You don't even hear of many of the Euro 4 engines with the electronically controlled EGR system fouling the valves and cooler like the older engines.

Hoping to view a 2003 V70 D5 (163) manual later this week. Do they have DPFs on that generation?

Its the age before most of the reliability destroying emissions equipment was fitted. The early Hdi engines are probably the best of all, I have a Peugeot 406 with 246k miles, still with original DMF, clutch, head gasket and injectors, I also have a C5 with the same engine at 203k with the same criteria. It only applies to the 2.0. 8 valve engine.

No.

No DPF
No swirl flaps
Much simpler EGR system.

Lovely!
Music to my ears! So other than standard diesel issues, dmf and injectors not a huge amount to worry about!
