Hi

Mercedes 300E diesel 1996.  I am having occasional start problems from cold.
It sounds like the engine is trying to turn over on a flat battery, but I
know the battery to be good.  Once it is started it is fine for the rest of
the day.  I usually park in an underground car park, and do not have this
problem, but parking outside is a real pain.  My local garage mechanic
thinks it may be an air leak into the fuel line via the filter, other than
that, he doesn't know.

No pressure, but if you guys can help me today, I would be very grateful.  I
am taking my car back to the mechanic tonight and leaving it outside his
workshop.  The temperature will be about 3-5 degrees tonight so he should
see the problem OK in the morning.  Otherwise it is over to you for help.

Many thanks
