You should have power from 1500rpm. The peak torque figure is 1900rpm.
On TDi200 there is no EGR valve - so that's not a quick fix !!
We had a TDi 200 and always found there there was plenty of pull lower down, noticeably better than TDi 300, so something is not right.
Here's a general list of things to check/replace:
1. Air filter - just replace it, don't faff around trying to clean it. You get a kit of the three filters (air, oil and fuel) from paddocks for about £11+vat so why muck about.
2. Fuel filter ditto
3. Do an engine oil and filter change - use 10w-40 semi synth.
4. Clean out the sedimenter on the rear chassis rail just infront of the offside rear wheel. DON'T try to open the little white plastic tap, it's likely to break and you don't get a good clean that way. Take the sedimenter bowl right off and clean it - only takes 10 mins tops. 11mm spanner needed.
5. Clean out the intercooler - use white spirirt or petrol but make sure it is THOROUGHLY dry before re-installation.
6. After checking the efficiency of your cooling system, remove the viscous fan and store in the boot. They really don't need them unless you get stuck in long queues of stationary traffic in 35°+.
7. Change your transmission oils for Evo1 (main gearbox) and Evo2 for trans box and axles - not cheap but ours ran noticeably freer and smoother afterwards.
8. Check that you don't have any brakes binding.
Hope that helps

PS The rev counter problem is almost certainly a lose wire on the back of the alternator - remake the connection and watch with amazement !!!
Anyone know of a GOOD diesel place down South?

The 200tdi is gutles from tickover especially when it's cold. However there are a couple of easy adjustments you can make to inprove it. Don't go too far though or you'l have a black cloud following you. Try here

Bit of a thread revival here, rather than start a new thread I'll ask here.
Discovery 200 Tdi recently transferred to my 110 CSW
Having similar problem to the OP - a bit of a lack in low end grunt, but as soon as the turbo starts to kick in at higher revs, she's flying. It's particularly noticeable in fourth gear when accelerating to cruising speed. Once I'm in fifth, I can comfortably hold 60mph all day long up hill and down dale, as the revs are high enough for the turbo to be working nicely.
The air filter is clean, and I've just changed the fuel filter. The oil is only 300 miles old. Anything else I can check?
Cheers

I would clean the little filter out in the back of the pump. It's inside the banjo bolt that handles the fuel return and it has a pin hole in it to clear as well. Check lift pump and then if no better, start giving it more fuel via the screw at the back of the pump half a turn at a time. That should cure the hesitation when pulling away.

Ok cheers, didn't know there was a filter there. I was going to try adjusting the fuelling anyway (don't get any black smoke at all once running). I'll see if it makes any difference.

Had this done to the 300 different vehicle all round

That's cool, good to see people have had positive results with it.
I'll give it a go later this week when I get a chance, along with refreshing my coolant, adjusting the throttle cable and changing the clutch slave cylinder...... Tis a labour of love...

Well, I had a go at increasing the fuelling today - think I got to about 1.5-2 turns before it started to get dark. It does seem to have made a difference - it pulls very strongly now at mid range, and still no black smoke, so I think I'll go another half or whole turn tomorrow and see how we get on. Also got to check the fuel sedimenter tomorrow as well.
