injectors for D5 needing work after 50k miles
Hi all,
Just had an oil leak fixed on the rocker cover and while it was off they checked the injectors. The result was that one was barely working while the others were also not as good as they should be. As getting at the injectors requires removing the rocker cover, I had it done. My question, is it reasonable to expect to have this work done at 50000 miles? Don't know exactly what they did, but it involved replacing something on each injector costing about 40 quid each. Cheers, Kevin |

you cant change parts on an injector they are complete units the only check a garage can do is a leakage check and if an injector fails that it will need a new injector .
If they removed the top cover then they will need new injector pipes perhaps this was the part? And you dont need to take the cover off to get the injectors out ,,,, No it is not reasonable to have this done at 50000 miles what ever they did , it sounds fishy ....

As Clan said, and I forgot to post, the injectors come out without removing the cam cover - Not sure if there are seals in the leak off pipes that have to be replaced if disturbed?

work on injectors
The local dealer, Kings Volvo, had previously commented on the engine running rough and it probably being an injector. I hadn't mentioned this to South Hants Volvo, so it is quite a coincidence if they decided to invent that fault. All I know is that they said one injector was barely working and the others were not working as well as they should. The invoice says "injector overhaul" at 38.50 per injector. Any ideas? I will be perfectly willing to phone them up and get a detailed explanation.

oil leak and 5 replacement in my Xc90 too
Last september I had an oil leak in my XC90 D5 MY07, combined with an oil level above the MAX mark (1-2cm). They made some kind of re-sealing to the engine to fix the oil leak. However, they didn't give me any explanation about the oil excess.
Since then, I have had to take it into the dealer 7 times because the oil level being above the MAX, which turned up to be an oil-diesel dilution problem. They changed 5 times the oil engine. Every time they did it, the problem (oil above MAX) reproduced in a brief period (2-3 weeks). They have tryed several things: a forced particle regeneration, replacement of 5 inyectors (with only 45,000 Km), and some kind of reprogramming of the engine (this was done by a volvo engineer via Internet from Sweden (I live in Madrid), with a laptop conected to my car). As the car is in guarantee, I haven't payed a single pennie. However, I am still waiting for a satisfactory solution after 5 months... Can you tell me if your VIN code is close to mine 3665XX? Maybe it is a manufacturing deffect affecting several cars. Excuse my English. Last edited by musicman; Feb 15th, 2009 at 07:42. |

one place fuel can get into the oil is from a faulty fuel pump have they changed that? Have they analysed the oil to see if it is diesel contamination?

Clan,
are volvo dealers doing injector fuel return or leak off tests? Diverting injector returns one by one and measuring fuel returned from each injector. Gives an indication of injector wear. The D5 operates EDC 16 with injectors being coded to the ECU (calibration coding) with the D5 having no ability to dynamically tune the individual injectors cycle by cycle? I wonder if the new D5 with piezo injectors will also get a engine control update.... The oil dilution case above where the oil kept going high. I agree, could be by at least one injector dribbling or overfueling. HPP seal is another one but also....if you vehicle is operating in town and is persistently unable to complete an automatic particulate filter regeneration (ie it starts the post combustion injector procedure but doesnt run long enough for the particulate filter to regenerate fully) it would then need to keep starting the procedure over and over again. This would dilute the oil with diesel due to the failed regeneration attempts. howeer, the ECU would be noting the post injection total time and the number of attempts so should have switched on the engine warning light with a code like "too many regeneration attempts" or "oil dilution above critical" That latter code knows how much excess diesel is allowed in the oil from regeneration attempts before the vehicle requires an oil change. At such an oil change, the dealer might need to carry out a forced regeneration depending on the mass of soot in the particulate filter and indeed if the vehicle's use was consistently preventing regeneration Do Feather diesel in Halifax not carry out D5 / EDC 16 common rail injector rebuilds? |
