PROBLEMS WITH XANTIA!

[espzetec]

OK, I have a 1.9 TD.
when the engine is running, i get a very slight noise. every 1-2 seconds on tick over. i can only describe this as a knocking sound. it increases with engine speed but is not so apparent as the engine noise drowns it out. it doesnt become worse under load it just speeds up i think.
secondly. again when the engine is running. i get a kind of hiss/squeel for want of a better word. i can only presume this is something to do with hydrolic suspension?
Brakes: i get a slight vibration under foot when i apply the brakes lightly. this only occurs for the first second or so when braking and then stops. again, is this a hydrolic problem?
final problem:
the rev gauge seems to work correctly when it wants to. it jumps about most the time, and not at all at others!!!
any help much appreciated

Apart from the rev gauge your problems could all be caused bt a flat accumulator sphere.
It's a green ball attached to the front of the engine.
Changing it isn't that difficult if you can get a decent tool to it.
