Am I right in believing that the injector on diesels should be replaced at some point in an engines life? If so, how do you know when that point is?
I have a record of all sorts of work that the AA carried out to my 110 while they had it but I can't see any mention of injectors anywhere. Hopefully that means that they are OK.
It has now done 146,000 miles so I was wondering what the symptoms of faulty injectors would be. At night I can see exhaust smoke in the lights of cars behind me but during the day I can't really see any. It also chucks out a puff of black smoke when starting and sometimes when working the engine hard.
So, does that sound normal or not? Also can anyone recommend someone who knows their diesels in Herts, I have had Oaktree garage in Peters Green recommended to me but I was wondering if there are any others.
TIA.
