Just spotted this thread has come alive.
An update on this car is well overdue, and it's not a great ending..... So, rockers replaced and done, car ran really well for 3000 miles and then my wife complained it the oil light was on... Sure enough, the oil was low but there was no sign of burnt oil or smoke. Did an oil change and it did another 3k before burning throught that lot. Decided to blame the DPF filter and changed that. Car was fine for another 3k, and this time less oil was used, although it more than I felt comfortable with. A mate took a shine to it, and my wife upgraded to a V50 D5. Anyway, mate had it for six months, DPF blocked again, oil low again... Changed oil, cleaned out DPF fine for a few weeks, and then it all came to a sad end and threw a rod out the side of the case. We put a low mileage D5 XC90 engine in, including using the turbo from the XC90 and it's been perfect since... I think the turbo was burning oil, but because of the DPF and low ash oil, it wasn't noticeable? Not come across another car like this since😁😳😳 |

Thanks for the update, the oil consumption and dpf blocking sounds very much like my XC70 euro4.
I came to the same conclusion re turbo, but (still) haven't got round to changing or replacing the core yet! The dpf blocking has been reduced by drilling a few 20mm holes asymetrically through it, but the side effect is the smoke is visible :-? my plan is to sort the turbo and if that sorts the oil/smoke problems then I might look at the lifters and followers to remove the occasional chug-chug sound!

Drilling holes in a DPF as some have mentioned is an MOT failure point and oddly enough, tampering with required emissions equipment is a breach of criminal rather than civil law. It can also partly invalidate the insurance policy, as it's an unapproved modification for no track only use cars.

Sorry to drag this old thread up but I am facing similar issues with my D5244T13. Deep engine note, almost blowy, poor MPG (e.g. on my 10 mile drive I lost 1.5mpg average from this tank of fuel and lost well over 100 miles of range).
The strange thing is this only happens when the engine is warm/hot but its frustrating as it doesn't happen all the time! I can leave it for a few hours and come back to it and it will be fine. MPG and range will slowly recover, until it happens again. I've just serviced it and it's currently on 193,000 miles. I have a new PCV valve ready to fit but taking out the dipstick briefly whilst engine running and having this problem makes no difference to the sound. Any ideas if it still would be the tappets if the problem is intermittent like this? Or is it the EGR valve? |

Tappets could be intermittent due to hot or cold oil (had this myself..under some cold conditions the thumping was not there)....in these engines with dpf its a common thing that the tappets fail and go soft....and if an exhaust tappet goes soft the exhaust valve closes later and burbs into the inlet hence the thumping noise.

If it is your tappets I would get them changed, my d5 snapped a rocker and took the whole engine out it was on 193500 miles.
Not sure what year yours is but was told 06 and 56 plates there were a bad batch of lifters and rockers that went soft not sure how true it is but I have a 10 plate engine in mine now and it is very quiet compared to my old one. |
