If you go to dieselgiant.com, there is an excellent article on troubleshooting the glow plug system.

The clunk when stopping is due to insufficient vacuum reaching the transmission modulator. In other words, you have a vacuum leak somewhere. On my car, the clunk problem was due to intermittent leaks in the vacuum switches mounted on the valve cover. I ended up just bypassing them to correct the problem.
