Hi guys, got a 1.2 TSI 2012 (but 61 plate). CBZB engine.
Quite as a mouse when it is idling normally. Turned it on this morning, and there's now this tapping sound? It doesn't go away after a few seconds or anything, no variation when the engine warms up. I can hear it in the cabin (normally you'd think the engine was off when idling).
84k Miles on it. I have since had the oil and filter changed later today, still the same tapping sound (a little quieter but still there, quite noticeable).
Is it really the timing chain going overnight? Or something else I'm missing?
