Caterham Idle Noise
Discussion
Thanks for the comments folks.
My dealer Oakmere watched the video and said that the noise is normal. Apparently the new (2016 onwards?) plastic plenum can be noisy around that area. Prior to that the plenum was metal (cast alloy?) which dampened the noise. Very interested to hear if anyone with a plastic plenum also has no noise, which would debunk this theory.
Also, they noticed my idle is really fast, ~2,000 RPM when it should be ~1,000 RPM. I think that may be contributing to a noisy idle.
Will adjust and report back.
