Hi guys,

I have a 2014 Subaru Forester XT with about 124,000km on the clock. It's been making a chugging noise on cold start and matches the revs, so I'm wondering if it's an idler pulley or similar?

Below I've found this YouTube video where the engine is making the same chugging noise.

Any thoughts or similar experiences?
