05 Toledo 1.6 petrol rattling noise on cold start

[Toledo Driver]

When I start car from cold it makes a rattling/tapping noise, sometimes louder than others. If I switch off ignition and then on again noise goes, then drive car and in less than 5mins car jumps/jerks and then seems fine until next start. Timing belt, tensioner and water pumps changed at 71,000km (Feb 009). Now have 108,000kms on clock. Think it may be Timing Belt Tensioner or Dry Bearing or Alternator Belt. Have car booked in with local VW dealer next week as no local SEAT dealer. Any help or advice would be great so that I have an idea once VW let me know their diagnosis.

I'd say either the coolant temperature sensor, or Lambda sensor. Both should show an error once plugged into a diagnostics machine
