Citroen Picasso Engine - cjwheeler
My 2001 Citroen Picasso 1.8 SX petrol has started making a rattling/ticking noise that sounds a it like a diesel. I can hear it when idling and it seems to increase in speed as I accelerate.

The car runs as usual in all other respects.

Any ideas what the cause may be? Is this something I should get looked at urgently?

Thanks

Chris
