MK4 2004 Golf 1.8 GTI - Diagnosis

Hi All,

Haven't been back here for a little while, and was hoping someone here can give some advice/or help regarding an issue Im currently having with my GTI, done a quick search here but couldn't find anything

It all started when I was low on fuel, and the low fuel warning light came on, the car started to shudder and loss of power, almost like it was chocking, (was just as warning light came on)
I filled the tank and it was still happening.
Took it to my local mechanic who does the basic servicing on it. He suggested it sounded like the plugs, so we changed them - still no good, checked the coils and injectors and assessed it was cylinder three fuel injector (code machine confirmed) He also did a compression test on cylinder three and it was fine. As he recommended they would need cleaning we left it at that as it was late in the day and to take back the next day.
Had another mechanic look at it today who did all the same tests and came back as an electrical fault to cylinder three (not firing) said the wiring from the ECU to the coil could be faulty and would need an auto electrician to look at and confirm, in other words could be a new ECU (worst case scenario) and to not drive.
Im thinking on taking it to VW specialist workshop?

Any help or guidance on what to do next is much appreciated

Jim
