Hi all.
My 2010 B8 S4 has started making an intermittent (every few seconds) rattling noise from the engine when idling. It sounds like a bearing or loose shaft noise, the video better shows what I mean.
I've recently done quite a bit of work on the car and not many miles since so hoping I've not left something loose.
I walnut shell cleaned the intake valves and intake flaps as I was getting the "P2006/7 intake runners stuck" fault code. Supercharger oil changed and charge coolers pulled and cleaned. Engine oil changed to 5W-40 as I was topping up frequently. Spark plugs changed and gapped. The car's done 116k miles. It's running a lot smoother now and no more engine warning light since cleaning and freeing off the intake flaps.
Can anyone easily identify the likely cause of this noise:
Cheers
