Whilst you may have genuinely had a faulty anti-shudder valve (intake flap motor), it is not related to the warm starting issue.

The warm starting issue almost certainly indicates a failing camshaft or crankshaft position sensor. Unfortunately, these sensors don’t always generate a fault code during the earlier stages of failure, when their operation is intermittent / dependent upon temperature.
I’d start by changing the camshaft position sensor, as this is the more likely culprit. Don’t be tempted by the really cheap ones, as they either don’t work at all or don’t work for long.

Cheers,

Tom
