Belt squeeling.

[mudski]

Mine squeals for the first 30 seconds while accelerating then stops. Have replaced the belt and tensioner. If I stop for ten minutes and start up again it'll do it for 10 seconds before it stops

Have a look at your egr pipe. If it does it while accelerating then stops, your motor is under load and high exhaust temps. As for the second part, when you stop the pipe cools, the metal shrinks and the split opens just that little more, then when it gets hot the metal expands, closing the split slightly.
Ive seen this before on a crd, but it could be something else too. Best thing to do is just make up a plate for the egr pipe on the exhaust side. So if the pipe is split it wont matter.
