Just an update on this, in case it helps anyone else out.
Car has been with the VW dealer in Tamworth for nearly 3 weeks now. Repeated repair attempts appear to not solve the issue. I'm not certain what the extent of their repairs have been so far (other than the initial two new injectors), I was told "wiring needs changing and re-coding" so I assume some harness has been replaced (not sure why that would need coding to the vehicle though). As of right now, I'm told VW UK technicians have advised to replace the inlet manifold, which is being delivered tomorrow and is being fitted on Monday. We'll see. Will update on any further replacements or progress as and when. What a faff.
I'll be contacting my lease company and the broker v. soon to apply some pressure to VW and enquire about some form of compensation. I'm paying for a GTI and I've been driving a T-Cross for the last three weeks. Pretty big downgrade...
