Did they give you an estimate? I have heard of timing chain replacemets
going as high as $800.

That is right, this would be anywhere between $900 and $1400, depending
on whether they have to replace the chain.

I cant see leaving it as it is causing any problems if you dont race it
around - it has a failsafe of falling back to normal valve timing so
you will just lose the top end performance gain of VVTi. If its the
actuator thats in the cam end you'll need a belt change, but it could
be the valve that controls the oil pressure to the VVTi mechanism, in
which case i cant see it needing a new chain/belt - you'd need it
clarifying , try to find an online Owners Club for your car and ask
there - they'll know the engine inside and out with any luck.
