Hi
i have balanced all four wheels last week. It's weird it only happens about 80% of the time.
it feels like a misfire rather than running gear. Maf, coils, plugs, lamda all changed. Fuel consumption is down to 25mph.
garage (Bosch specialists) are just randomly changing components so costing at the mo.
i had same issue on a 1.8t and practically changed every component on car including flywheel clutch and both subframes.
the AA ran a diagnosis last week (vw specialist) and mentioned it needs a software update but diagnosed lamda sensors. Was wandering if the software update is required. Any thoughts anyone?
