E39 525tds 1997 with rough idle and shaky
My '97 525tds with over 300th km's has a rough and shaky idle on some occasions. When the engine is hot, it often starts to shake when I put it in neutral or use the clutch when heading to a stop. When I come to a stop, it disappears, or by adding a little gas. There is no lack in power and it's never with a cold engine.
The car has a full inspection history from 0 untill now, last two inspections (I and II) I have done myself using the TIS inspection manual.
I have looked for vacuum leaks, changed the dieselfilter once more, cleaned the AGR valve and read out the computer with my carsoft interface, no faults detected.
I am planning on checking the injectors and timing, but can't do it myself. So to save costs, does anybody have an idea what this could be?
Thanks a lot!
