Misfire
#5
Ah, you're not that near me then (Bristol Way). Not much point in offering for you to pop over to plug in to PP2000. Am pretty sure there will be someone closer with it.

I had a similar problem a few years ago n like you went down the route of replacing all the critical sensors in the hope of solving the problem. It's a fairly hit n miss strategy n potentially expensive too. You could replace them all n find you still have the issue. Like I did. That's why I'd approach it differently now, particularly as using cheap replacements can make things worse.  I used an unbranded MAP sensor & it ran like a dog. Now use Bosch if poss, or Intermotor or Cambierre likely to be OK too. 

Many of the sensors can be tested to a certain extent with a multimeter n checking they receive the correct reference voltage is important. The 306gti6 site has a guide. http://www.306gti6.com/forum/showthread.php?id=80340.

Btw, my misfire was, in part at least, due to a poorly fitted cam belt which had altered the valve timing slightly. I haven't mentioned it before, but the EVAP system is also a potential source of issues. Paying a good garage (with a reputation for quickly diagnosing issues) could save you money in the end.
