Diesel Particulate Filter - recall
 

I had a recall letter from my dealer in Northampton
--asking me to take my 2006 S60 D5 in for a recall.

Recall Campaign A29101

Something to do with the Diesel Particulate Filter - DPF ??

I took it last Friday and was told that they had found that bio-diesel fuel was leaching into the sump and raising the level of oil in the sump?
Their action for cure:-

Drain of oil in the sump to about 2/3 on the dip stick
Do a software update so that the oil level light don't come on too soon ?

I asked:-
-- if they had marked the dip stick with the new level -- NO.
-- if there was a new dipstick with the now corrected [?] level - NO
-- can you tell me the new capacity of the sump - NO

This concerns me as if I put my car in for service - the "mechanic" will fill the oil to the full level on the dip stick.. and so may cause problems..

Should I get a plate engraved to fasten to the dip stick to say "only fill to 2/3 full"
Should Volvo be more proactive and provide a new dip stick?
and or a label

Have others had this recall -- and what has been done??

So what is the recall on the DPF about?

The rising oil in the sump is a known problem caused by the 5% bio additive in the diesel fuel. The only diesel fuel that does not have this bio additive is Shell V-Power Diesel. This instead has a Gas to Oil additive exclusive to Shell. If you keep having this problem and it can't be fixed then try this fuel.

Have done a lot of reading up on the DPF on all makes and the following is the general consensus.

All manufacturers of euro IV compliant dpf diesels have regeneration problems if :-

1]the car runs on cheap diesel :- use low particulate diesel such as shell v-power and Bp Ultimate to eradicate problems

2] If the car is used on short runs and the revs rarely go above 2500, Run the car in lower gear with revs of 3500 for twenty mins to clear DPF of soot once every 400 miles.

3] The driving style is gentle and pedestrian. Give it some welly and apparently the engines loves it.(I drive like a granny so this one is hard for me)

I personally have had no problems but I use V-power diesel now as it appears to be worth the extra cost. Car runs quieter and has not regenerated since using it.Mpg seems to be 2mpg better but early days yet!

V-power also has added Liquified gas rather than bio diesel.Bio diesel is supposed to be the cause of oil levels rising as it gets into the sump during regeneration and does not evaporate.

Diesel particulate filter and rising oil levels discussion
 

There are a number of threads scattered around the various boards for the models affected and it has been suggested to keep the discussion here as the issue is particular to the engines and not the cars.

All the other discussions are indexed in that thread and can be linked to from there to read the previous discussions. If you know of any other discussions let me know and I will add them to the list.

This problem has not gone away
 

Hi
This problem does not seem to have gone away, I am a new poster on here because up to now I have owned a 2002 V70 D5 SE Auto that has been pretty bullet proof. Last Thursday I collected a 2007 registered C70 D5 SE LUX Auto with 42,000 miles on the clock and full dealer service history.
From the decall on the bonnet slam panel it appeared to have had the DPF/overfueling mods done and, looking at the paperwork and the dipstick, the dealer had done an oil and filter change with the oil level at the maximum mark. not the 3/4 mark that the new decall suggests. After a brisk but not silly 150 mile drive home along a mix of motorways, dual carriageways and fast A roads the engine service light was on and the dipstick showed that the oil level had increased by around 8mm. On Friday I accessed the stored codes and found EMC codes 6663 (heater plug/ relay on number 3 cylinder) and 5660 (oil level faulty reading) I therefore removed sufficient oil to return it to the reccomended 3/4 full level using our oil sampling facilities and this sample is on it's way to the laboratory. The engine service light went out after I cleared these two codes.

On Saturday, after an early morning cold start, there was no engine service light showing but out of curiosity I used the code reader which showed a fault code EMC 6663 so presumably I have a dodgy heater plug/relay.

Having driven the car around for about 50 miles over the weekend mainly on short local runs with the occasional bit of motorway the engine service light is back on and the oil level on the dipstick is marginally above maximum ie an increase of about 6mm, so in 200 miles the oil level has increased by around 14 mm or the equivalent of 1/2 litre of diesel entering the oil.
