It's not just the belt, as you can see there is a comprehensive list of parts that would be replaced. Here's an extract: :shock:
Service Action
Check of the noise coming from the camshaft drive chain.
Identification of the type of camshaft drive chain fitted to the internal combustion engine.
Replacement of the camshaft drive chain with an 8 mm chain (Modernisation of the internal combustion engine ).
Engine management ECU downloading (if necessary).

Parts required
1Camshaft kit (Part No. 16 381 598 80).
1 Camshaft pulley bolt (Part No. 0806 49).
1 Crankshaft pulley bolt (Part No. 0516 A3).
1 Camshaft seal (Part No. 98 239 200 80).
1 Seal (Part No. 3111 27).
1 Timing belt kit with coolant pump (Part No. 16 289 261 80).
1 Injection pump outlet pipe (Part No. 98 162 963 80).
1 Cylinder 1 injector supply pipe (Part No. 98 117 373 80).
1 Cylinder 1 injector supply pipe (Part No. 98 117 375 80).

1 Set of oil separator seals (Part No. 16 381 593 80).
1 Set of vacuum pump seals (Part No. 4556 24).

1 Diesel injector return pipe (Part No. 98 247 231 80).

N.B.: To optimise logistics, the parts kit available contains the camshafts, the camshaft carrier, the chain, the tensioner and an information label to be affixed in the engine compartment
Went out to my car this morning and started it up with a horrible thud noise from the engine coming from left side, noise disappeared on first rev but got it booked in as it originally sound like the bottom end was dropping out

Sounds like a ticking to me - what is this a C3 or C5 AIrcross?

Yours has a 7mm timing chain (pictured at '3' below), and the actual build date of your vehicle is 13 December 2019, so would be one of the affected blocks despite it not being a Euro 6.3 (yours is Euro 6.2).

So very likely yes.

Not unless it has been booked in for this issue after being diagnosed with the timing issues - it has not been the subject of any recall at present.

To determine if it has had the work done, either check the reference number on the casing as described in the first post, or check with a dealer by giving them the VIN / Reg and they should be able to access any historical repairs undertaken.
