I have just been to one of these with warning light on and "check injectors" message on dash-board. Fault code PO670 was stored (Pre-heater Control Unit). This vehicle runs fine etc and code cleared down. However, it came back on again this evening - hence this rummage through the archives. My question is: Did your car have starting problems ? This one hasn't - maybe it is not cold enough yet. I am not well versed in diesels and if it has a glow plug fault, would it be prudent to change all 4 and are they a problem to replace? Your thoughts would be appreciated.
Regards
Pete M
