Thats the same plate that holds the acc cable

That plate should be seperate to the rear plate that holds the pump....

I'll take a pic for you

When Land Rover upgraded from the 200Tdi to the 300Tdi, they did a number of things that lead to the timing pulleys getting misaligned, causing the belt to track off and wear away.

The cover that the injection pump mounts too was distorting. Only the idler pulley had flanges to prevent the belt running off. The tensioner gets out of line. The pressed pulleys pull out of line under belt tension.

Besides the support bracket between the engine block and the rear of the pump, and the timing cover discussed above, they have:

Changed the tensioner assembly, changed the crankshaft pulley to one with flanges both sides.

The new idler pulley does not have flanges now. It is not unusual for one of the flanges on the crankshaft pulley to be worn away.

Wear in the idler pulley bearings allows the pulley to misalign, so it is always safer to install a new kit.

There was a factory direction, to reduce the torque used to tension the belt (before tightening the bolt in the tensioner), from 14 Nm to 11 Nm. The workshop/overhaul manuals still state the old value.

The system is so poor that the cr&p pressed pulleys distort and the idler pulleys move under the belt tension.

If you refit the support bracket at the rear of the pump, you must be careful of the procedure, so that it doesn't pull the pump out of line.
