you can connect a glow plug up to the battery and it should glow red hot within a few seconds.

mount it in a vice though and let it cool for several minutes before touching it.

When you remove them check for damage, if they are damaged even slightly replace them.

Just another thought, I had starting problems on the last diesel I had, wanst a disco but it turned out to be a pin [ed - prod with a sharp implement] hole in the fuel supply line.  Only affected starting.  I put a clear fuel filter in the fuel line, like the filter used in old ford sierras, its an inline filter so you can move it around the system and look for air bubbles.

Some 300's need a slight timing change to the pump. Not sure if it can happen to a 200tdi. Paul might know. He did his 300tdi.

My 300tdi was slugish to start when cold,

Checked all the normal stuff like, Battery, Glow plugs etc...

In the end I found the timing was out. :roll:

If you have had the timing belt done reasontly that might be the problem.

a mechanic told me an looking on other threads to confirm , it can take one worn/faulty glow plug to cause problems when cold starting !! :?
if its starts fine in the warmer months and gets worse in the colder months you've got your answer. !!

Last week, my 300TDi wasnt starting too well, it took the 3rd attempt before it fired correctly. Over the last few days it has been fine, but my thoughts are that the diesel itself may have been waxing a little...... dunno if this is correct or not but no doubt someone out there will put my head straight :)

Apparently........  direct injection engines should fire up pretty easily without glow plugs.  

I had a similar prob with mine at the start and air was getting in the system from the leak off rails.

Also check your lift pump. Fuel may be draining back overnight and thus a !Expletive Deleted! to start. Replace if necessary.
