I'm looking for a source of refurbed injectors for a 2006 Facelift E220 CDI. It's difficult, as with all things, it's hard to know if you getting quality items from a reputable source, or a bit of a bodge job! Two places I've found from google ads (never a good sign!) are: Specialist Diesel Injection Services Ltd. bosch_inj However I have no info on them. They look OK, but has anyone tried them? Is there a better source that's reasonably priced? Thanks!
