timing belt

You don't, they are adjusted when they are fitted new, if it has stretched & become slack replace it,

Steve.

are you therefore saying, as it stretches the timing goes out. There must be a way of resetting it while this happens.

You need to find out if your engine is what's called an interference engine. If it is and you have been turning it over you will have bent some valves probably. Best to find out before you mess with it anymore

A £ saved can be £££££££££££££££ lost...........

Why didn't you replace the timing belt at the same time?!

have a look here

There is an article on setting up and replacing a timing belt on an Audi - it is not the same model as yours, but will give an idea of what is involved in setting the timing properly.

Does Haynes not cover timing setup for your car?

Unfortunately, if your engine is an interference engine, you might have caused quite a bit of damage internally already, but you may be lucky!

Buy a manual, find the timing marks, line them up, refit the belt, pray very hard nothing is broken.

The message from "mw3" contains these words:

Read the Haynes manual for that engine. It'll tell you how to set the cam sporcket and the crankshaft in relation to each other to get it all together.
