I sent 5 injectors in for testing, all were failures due to coil resistance or flow rates. I asked for them to be cleaned as per the listing & returned. In my opinion they had not been cleaned as there were still significant carbon deposits. I then tested the coils & all appeared to be showing exactly the resistance that they should be when tested as per online instructions. I do not feel that I can recommend the service as I still have a running car as I did beforehand and am worse off for it.

Siemens injector coils, primarily piezoelectric stacks, are prone to failure, and replacing the stack is nearly impossible due to the lack of spare parts. If damaged, the entire injector must be replaced. Resistance testing of Siemens injectors requires a special insulation resistance meter, not just an ohmmeter. Measurements should be taken under consistent conditions, as temperature changes or nearby interference can affect results. Care must be taken to avoid damaging testing equipment

As advertised, good price we'll packed for shipping and fast delivery (ordered late Thursday evening, arrived Saturday morning). Injector looked like new, in sealed packaging, with all new seals etc, test report and some other useful information included. Installed and all good so far, engine running much smoother. Would definitely use this company again.
