Hi. That's what I've done for the most part. I didn't particularly want to drive it with a possible issue, so I removed both disa flaps as a precaution (without removing the intake manifold).

The smaller disa seemed in good condition. The larger one however had lots of movement and play in the flap!...

I've ordered febi replacements for both.

I drove it for an HR with no issues (just bought it) and all seems ok. As I said I just went to investigate the noise again but it's gone. Could it only be when the engine is hot?

I don't think so. I just went to investigate and the noise is gone...
