HI,
I think I need to change the head gasket on my A6 1.9TDI 2000, as I'm getting pressure in the coolant expansion tank, but no other symptoms.

I'm told that I need to remove the bumper to be able to get enough room to change the headgasket, but looking at it I think I can get in (it will be tight), can anybody confirm this?

Also if I cahnge the head gasket, I assume I need to change the bolts, but what about any other gaskets. The head gasket seems to come on it's own and there is another gasket set, do I need it?????

Also how long should it take to change and is there anything I need to be aware of?

Any advice greatly recieved.
