I have a 57 reg Focus 1.8 TDCI.
Have also got a 1.6 58 dpf version as well.
Have a noise when coming off revs on the 1.8, hard to explain, kind of like a metallic vibration.
Dealer said it was engine cover laying on air con pipe and they had sorted (but they havent)
Anyone got any ideas what it might be, or whether it is normal on the 1.8.
My 1.6 is a completely diff sounding engine
