this comes from mondeo forum.After speaking to both Delphi and a large Delphi agent today, I think it may be worth passing on some info regarding reconditioning of TDCi injectors.
Hopefully this can be made a sticky as it is a question that comes up regularly.
After having my injectors reconditioned 18months ago by United Diesel, my injectors are now shot again. That is approx 20,000 miles for the injectors to fail. If truth be told, there was only the first 8-9 weeks when they ran well. After that the cold start smoke returned. Keith at United Diesel suggested I return them for him to recheck and after he suggested they were fine, even though the smoke was still present. The smoke has gradually increased on cold starts till there is an embarrising plume again. A few days ago, one of the injectors stopped working all together. United Diesel are not willing to correct any wrongs and suggest any failures will be down to parts used and should be taken up with the relevant manafacturer which could take anything upto and beyond 12 months. The price for 4 reconditioned was £460 that is £115 each.
At the time I had the injectors overhauled, I had the option of getting the job done by a local Delphi agent. The deciding factor against them was price. The Delphi agent wanted around £143 for each injector.
Today I spoke to another leading Delphi agent Merlin Diesel in Preston:

According to both Delphi and Merlin, any injector that is taken apart and overhauled should be put through one of their machines to give it a new 16 digit code along with checking that it works correctly within the parameters. If a new code is not used, the injector can fail prematurely. Merlin added that the 2 parts that are usually changed (nozzle and valve) aren't enough and that the valve sandwich plate should be changed as well. By doing this, they have had a massive reduction in failures.
The price for a reconditioned injector from Merlin is £115 + 15% VAT = £132 x 4 = £530. There is the fitting and recoding on top. Recoding should be around £40 as long as you don't go to a main dealer......fitting will vary on price. It is a 15 min job to remove and refit the injectors and in reality shouldn't cost anywhere near the £125 Ford charge.
If I knew 18months ago what I know now, there is no way I would have gone to a NON delphi agent to recondition my injectors. For the price difference it is worth a Delphi agent doing that bit extra and checking the injectors properly.
