Hi, it looks like you have the same or similar model that I have. How
difficult is it to change the glowplugs? It looks like they are covered by a
piece of plastic shroud on top of the engine but I am not sure how exactly
to get to them and the manual is no help. Can you help me?

Thanks a bunch!

Ahh... yes, same engine as mine. I just did mine... it is quite a bit of
work. You have to take off alot of thing... especially the intake manifold
(which you need new gasket to do this job). It is not a hard job... just
alot of things to take off. Since your car is 9 years old, you should
consider chaning all the fuel lines while you are at it... because it is all
fully accessible at this time. I also changed the injectors return fuel
lines at the same time.

Tiger,
Speaking of fuel lines, what's the ID of the overflow lines which go from
injector to injector on 240D and 300Ds? I want to use the newer translucent
tubing which doesn't leak after a short period of time.

1/8" ID... It is best to use the biodiesel compatible hose. TG bought some
that he say never leaks from NAPA... but I don't know if those are biodiesel
compatible.
