w210 300td glow plugs
For anyone changing the glow plugs. Never give up and take your time is the key. You can do it yourself , borrow some tools of your mates , and then put the car on some ramps. Tell the wife you'll be back on the road in about an hour, then .........
6 1/2 hours later 
job done. first 5 plugs 35 minutes, the last 1 was seized in 
, Oh yeah nothing special done, I used nearly a can of WD40 and patience, lots and lots of patience. the key to it is just don't rush and take your time.. Good luck . A lot of thanks to all that posted advice on how to get the manifold off and the pitfalls of rushing the job ... Thanks.
Next job front suspension clunking so bushes and other bits.... It should be fun...

Did them (only 4 on my engine) myself about two years ago. I was lucky they came right out! I didn't have a torque wrench at the time so I fear I might've over-tightened them. I'll find out next time one of the plugs wears out...
btw, upon removing the manifold I found out how much sooth and grease buildup there was because of the EGR system. Removing the EGR became my next project! It cannot be done on your 300TD however...

OP doesnt say what year his is. Appears to be a wagon (TD) so ought to be a 96 or 97. The 606.912 egr is easliy deleted.
The .962 requires an electronic delete; search "E300 EGR Delete" and "Kartek" using advanced search features on Peachparts.com to learn how to do this.

300TD can also be TurboDiesel
Mine's a 604.912 it only has a air-inlet-temperature-sensor like the 606.912 300Diesel.
The 300TurboDiesel has a MAF and needs an electronic delete indeed, the ECU checks EGR functioning by measuring airflow through the MAF with the EGR valve open vs closed...

egr
hello,
new to all this techno speak I think the egr is the bit from the turbo pipe to the inlet manifold,
I didn't manage to get this off as someone had kindly nackered the allen bolt holding it in , so I had to undo the 4 torx bolts to the manifold from under neath, (actually wasn,t to difficult). got the inlet off to reveal to glow plugs..
when I get to the ball joints. bushes and drop links I'll hopefully post another success...

All been worked out on the 606.962 using off the shelf (Radio Shack) lil electrical do-dads. Costs $15-20 to make. Disables EGR by emulating electrical parameters ECU monitors.

Thought I would give you guys my two cents. On mine, the number 1 glow plug went bad, total open, I revmoved it yesturday evening. This is how I did it, by the way my Diesel has 93K on it:
1. Use lots of WD 40.
2. Take your time.
3. Be attentive when you break it lose then work it clockwise and counter clockwise a quarter turn or less to break any carbon/trash build up.
4. When you start to unscrew it, go slowly and if you notice any, I repeat any resistance, stop, saturate it with WD40 and let it cool down.
5. When you are unscrewing the plug the friction causes it to heat up enough to expand and it will get tight......saturate it with WD40 and give it time to cool down, you will find that it will start to turn again with less resistance.
6. As you are unscrewing it, again, besides letting it cool down, work it clockwise and counter clockwise a quarter turn or less to break any carbon/trash build up.
It took me about thirty (30) minutes to remove it but was sucessful.

Couple of things i would add.
1. Take top cosmetic cover off first.
2. Take car out for a short run 5 miles
3. And when i've loosened the torx bolts on the inlet i use a drill with a bendy adaptor to remove the torx bolts quickly.
4. I have a (shallow) 10mm socket, standard 10 with paper wadding to make it shallow for the turbo inlet clip.
these things make it easier to get to the job.
