I have a 1.6 2011 golf. Starting having the revs jump about and then eventually started cutting out. No fault codes stored. Automatically I assumed fuel filter may have started to block. Put a new fuel filter in and managed to get the car to run for a few minutes but sounded like possibly 2 of the injectors were making a ticking noise and then the car would not start again. If the injectors are not performing as they should would I have any fault codes stored in the car? as I've seen previously injectors do not always give you fault codes if their not performing as they should. I could carry out a leak off test but unsure whether this would definitely confirm that the injectors are to fault. Any advice would be grateful.
