3-series 2005 E46 Touring 46kmiles 318i exhibits a 'metallic clatter/chatter' at warm idle is this normal? No different after oil change.
Also I find that at low RPM, circa2000, noticeable when changing up, the car tends to lack power. It takes careful operation to avoid a stutter when changing up. Top end above 4000rpm goes very well, is this normal for this car?
Or I am spoilt in my Astra G 120kmiles 1.6 16v estate which is superior in this aspect?

Is this coming from the front of the cam-box area? VANOS unit gone?
Can you confirm that this is an N42 B20/A engine?

Screwloose thanks
How you I find about engine type/number?
Do you mean the DOHC 'rocker' box for cam box?
How do I recognise te VANOS? (=VVT control?)
I as thinking more of timing chain noise vs tension adjustment?
