*HELP* 2006 Urban Fox Misfiring. Where is TDC Sensor ? Changing coil pack & plugs didn't work.

[D1CKY]

I have a 2006 1.4 Urban Fox on 42k miles that has just started misfiring and has a engine light illuminated down the bottom right of tye instrument cluster.

I have plugged the car into Diagnostics and got back a 0304 code telling me cylinder 4 was misfiring.

I then went to change the coil pack as it was one of the parts listed as a possible cause on the Diagnostics scan and is a common VAG problem.

I fitted it and and nothing changed, i then changed the plugs for OEM NGK ones as they had never been done.

The leads are ok.

My next step was to check the TDC Sensor is functioning as it should and give it a clean if required.

I cannot locate it around the bell housing area (I must be blind).

Can someone tell me if this car has a TDC sensor or a cam sensor ?

Assistance welcome.

Fire away with ideas.
