Hi all. I've noticed a rough/slight rumble to my Idle. It only happens when I've done some short journeys about town, low speed, stop and start & even once the engine is uo to temp. If I've been on a good steady run like my commute I don't get it. It's not the DMF I don't think as engaging the clutch doesn't stop it. I had the exact same thing on my old 2006 T5. Is this just something to live with or is it the start of something that needs sorting?
