Just a small update, had a service at awesome recently and they discovered that my fuel filter was contaminated. After looking on here I came across volksmaster in bury so I took the car there as it is not far from where I live. They replaced a cv boot and did a brake fluid service with super blue brake fluid.
They also replaced the injector seals, ultrasonically cleaned the injectors and replaced the tandem fuel pump gasket. The injectors are now spotlessly clean! Don't no if it's just me but the car feels a lot better. I would definitely recommend volksmaster, they are a good bunch of lads and the service was spot on.
