When my A4 1.8T did that it turned out to be the key (RFID Chip) it started and cut out after a few seconds. Tried the spare key and nearly fell over when it worked.
Could be anything in reality and as said you need to run a diagnostic on it.

Could it be anything worse than the above like cambelt or engine knackered?

No.

Look on here for a member closest to you with VCDS, get a scan and report back.
