Well according to Fords Maintenance Schedule the Eloy's additive reservoir [which your car has] should be refilled at it's third annual and every sixth year service and so one or every 37.5k whichever comes first. The car in question being on 44k, well I doubt in all honesty that it will have been done. Lets be fair if you were moving your motor on after three years ownership, you would not pay for a service prior to selling it. Nor would you spend the additional £150 or more that dealers are asking to refill the additive reservoir and the ECU reset.
If I were you having it done would be part of the deal, and I'd want a stamp on the log book stating it had been done prior to you taking delivery of the car. Research the cost of "Forced Regenerations" or replacement Filters and you will understand why I'm telling you it's important that it is known to have been done.
Read link in my sig relating to DPF's.
Forget the £1,000 service quoted in the opening post on the linked to thread, peeps on here have recently had quotes of over £1,500 for DPF replacement.
Cheers for the reply. I am buying the car from a car supermarket (not Carcraft) so will have to investigate what has been done already, though I doubt there is any wriggle-room to get them to do it, as they operate a very strict policy on negotiations (ie they just don't do it) so it may have to be something I get done as soon as I collect it.
However, other than it being recorded in the log book, is there any visible checks an owner can do to check whether it has already been topped up?
I apologise for all the questions, I have been reading up on what I can find out, but searching on my phone isn't the easiest thing to do.
