A work in progress.

Yep.

I've set a new record !

Unfortunately, it's not a fuel economy record

The most recent Diesel Particulate Filter regeneration has taken a whopping 78 km (that's 48.5 miles !) instead of the normal 10 km (6 miles)

Over this 973km (605 mls) tank, the DPF has been regenerating 7 times, over a distance of 185km (115 mls) - or during 1 in every 5.26 km/mile !

During regeneration the fuel consumption often doubles on the OBC, so the overall FE suffers greatly.

Better check the oil level once more, tomorrow morning.

Back to Ovlov ?

Gah!!!

This is not making me feel comfortable with getting a diesel..although I'm tempted as 50+mpg with out trying would be lovely.

You have the patience of a saint.

Not quite
So far, I haven't seen a bill for the work nor for the replaced parts, so I'll give them some slack.

Never going to happen.

Though the fact that I can now do 70 kph in 5th with similar or even lower fuel consumption as in 4th, makes me wonder how long those defects have been there. That didn't work out before, and I know I've been trying it back in 2009.

The "control" sample here seems to have been Snert - you got 21% over govt figures and I seem to recall no regen issues when you had him ? And I assume you drove him like you wish to drive Hagar ?

320 - Just avoid a Diesel with DPF ?

I'd have to agree with him here Euromodder.. modern engines are built to microscopic tolerances, so there should be little/no difference between cars.

I know if you're on this site that you're not thrashing the car..and darn tootin you should see no bills.

How about asking for them to provide you with a replica of your car (there must me one of a similar age/spec/mileage in the dealer network) that way you can compare apples and apples-another thing to consider is take a volvo mech out with you whilst you drive so tehy can see the regeneration/driving style/conditions?


As for DPF- I'm tempted by 1.9 tdi PD lumps or the bulletproof 1.9SDi

Yes.
Driven the same way over the same route, the S40 got 10% better mileage.
The S40
- is 0.01 Cd point better;
- has 195 / 15" tyres instead of my 205 / 16" ;
- has 2 tyres of an older, less efficient version;
- has far bigger mirrors

It regenerated fairly often as well, but only for short periods, and unnoticeable if it weren't for the ScanGauge.

I've spotted 4 regenerations in 1500km, but I may have missed one.
Quite a few regenerations on my V50 last longer than those 4 combined .

320 - Just avoid a Diesel with DPF ?

That would be my advice if it has to be a diesel.
There's plenty of troubles with them - it's not limited to Volvo.

Better search one that will tolerate biodiesel than one with a DPF.

Working on converting a BMW...turns out it is still not easy to find the parts, EMotorWerks is a good source, prices are great.

Any updates on the regen issue ? This hit UK TV last week with the BBC Watchdog program reporting issues with several Diesels - mainly FIAT 500s and Nissans but obviously not limited to those. Also just read a couple of mag articles and ads

- A reprogram of the ECU to disable the DPF - not sure how this is done.
- An additive which cleans it out
- A description on how to clear it out manually
