I think he is trying to say he has a different point of view? :

Indeed, I got that impression too.

Keep it civil please.

Thanks,

Its great when someone else trys something that shouldnt work and finds it does work especially when its not me paying for the experiment , when the injectors time has come I will now have no hesitation in pulling them apart and trying to get them back together knowing that someone else did it first , ultrasonic cleaning get away , I will use a Brillo pad .

Well .... a year later and the same injector #1 replaced by Volvo under warranty need replacing !!!

What is the likely of ths happening ???

Does anyone knows if Volvo fits recon injectors under their own warranty scheme ? I suspect they do as the my local indie that has no replaced the injector was told by Volvo he needed to return the faulty one otherwise the charge will be higher !!!

Sound like a rip off to me at £230+vat for an injector AND faulty pone to be returned to volvo

I agree I also think its very unlikely but garages get away with this because most normal motorists like myself dont know enough about the component to question them , I have been repairing all kinds of things that are supposed to be unrepairable without professional help and expensive equipment and once you have discovered what it is that caused the problem and worked out a way to fix it it for next to nothing there is a great deal of personal satisfaction to be had in doing it . I would be very interested to hear again from freshlo who took his injectors apart earlier in this thread now that some time has passed to see if he is still motoring with the same injectors as I am not brave enough to do this myself due to all the warnings you read about it but if someone else has got away with it then I will be willing to give the needles a polish with a brillo pad . Has anyone done a step by step guide on injector cleaning in photos something similar to the one on turbo refurb would be great ? I think that the official refurb procedure is maybe do a test on them and then replace springs and seal and do the ultrasonic clean on them and at £234 each that sounds a bit steep to me ?

hi there, the volvo problem is not unique to the D5. I've got a 51 reg D5 that has now done 163,000 and yes starting problems. interestingly I read on the forum that one member was pouring hot water on the injectors to get it to start. A gentle warming with a heatgun resulted in that the car started easily - not very practical when out and about. The problem with common rail diesels is that the injectors are very very delicate and sensitive to the quality of the fuel.

I took the car to a bosch specialist and did a leak test (£40) which showed that one injector was leaking badly. As the car is getting on a bit I didn't fancy the relatively huge bill and working with fuel and chemicals I fancied trying a very strong fuel injector cleaner and from not starting without heating the injectors with the heatgun it now starts. I'm now down to 5 seconds when it has been standing for a couple of days and temperatures around 5 degrees C. Since first adding the fuel injector cleaner concentrate I've done 2000 miles and it is getting easier and eaiser to start.

so consensus is that it is not a mechanical failure - it is a build up of varnish which can be avoided if fuel injector cleaners are used regularely. I'm going to try another mix shortly and let you know if the progress is still positive.

when you buy your normal fuel injector cleaner they only contain 2% of active fuel injector additive (the rest is typically karosene). these normal fuel injector cleaners will not be able to clean a failing injector. the ones that I'm testing are 100% concentrate.

the car goes also much better since starting the cleaning procedure and much cheaper than changing injectors.

That woudl certainly explain why Volvo wants to have the injector back ... a bit of cleaning and then pronto a recon injector that can be re-used in any volvo that is still under manufacturer warranty !!! Nice profit for Volvo byt rather expensive for the end user !!!

What make of injector would you recommend and what sort of dilution ?

I am still not convince that I would return the faulty injector to Volvo as at £220 for a replacement, I think I earned to right to keep the faulty one ....

Anybody with experience of buying spare against returning the faulty part ?

sorry been working too much since last posting. I'm trying a new product that is highly concentrated and now after 3000 miles the car starts fine and runs really sweet. on motorway journeys at constant 78 mph on the clock it returns 54 mpg easily. I did an injector leak test when I started this trial and will do another one in a couple of months to see what the diffference is. the problem is to find a high concentration injector cleaner on the market. If you are interested I can send you one to try (I got this from an american company to try so more tests would be excellent).

hi hilda

ive had the starting problem on my D5 S60 after just one month of ownership. I wouldnt mind trying to get my hands on some strong injector cleaner, are there any good brands in the UK?

however a friend of mine put some in his audi and apparently it destroyed the fuel filter, resulting in bits of filter entering the pump and messing up 2 injectors in the process,
