If you swap the plugs and coils around and the problem remains on the same cylinder, suggests a failed injector.
I would not drive the car anymore!
Give R-tech a call, they'll be able to help you. Get the car there (somehow) Or get the injectors out and sent to them and their 'Injector clinic' for flow testing, then cleaning and rebuilding with new filter buckets.

 

Tried all that mate already sent the injectors away, and the results are back from r tech...

3 bad injectors

Need to source more

Jesus those are bad! Should be all around 66? If my memory serves me right, mine were all above 60 but some lower than others, think they said 56/58 was low enough to run lean enough to start potential hot cylinder pressures/damage-melting to the pistons.
Assuming under 60 ones are not saveable? Least you have the results and should be able to fix the issue man

 

How big a job is it to get the injectors out?

 

Wasn't to big of a job the fiddly part was removing the inlet manifold, I have done a compression test and they all came back at 175psi per cylinder, I've ordered new injectors as the old ones were to damaged, apparently the worst ones they've ever seen lol, new parts have arrived

 

It's alive !!!! Turns out it was the injectors, new ones have been installed, valves cleaned from carbon and rubber flap delete installed

Massive thanks to r tech for all their help would highly recommend speaking to these guys if anyone ever has a similar problem [emoji1362]

 

How much were the injectors?

 

£110 each from awesome gti mate £452 inc postage

 

Glad its sorted!

Is there any ideas as to whats caused them to go so badly? Is it a high mileage car?

 

It's done 80,000 no idea of cause guess it's just wear and tear ?

 

Cheers. It's looking like mine are also playing up.

 

Ian get them sent or get the car up to R-tech to get it all sorted. They are good blokes and know exactly what they are doing.
Injector cleaner I hear helps brake down the plastic filter buckets and block the injectors, these are then replaced with metal ones by R-tech.

 

Does the Injector have filter at the top?

I'm not sure mate r tech will know if you give them a bell

Yeah might message them, may be worth the mega trip up there if they can do it in a day.

 

Looks like mine has gone the same ok one day left for a month, then bang running like rubbish, swapped over plugs coils still the same , say cylinder one and multiple misfire
