Banging radiator noise

I've been having some recent issues with my bedroom radiator. It is banging every 20 seconds or so, only when heating. We have a central heating system based on hot water in our flat, and my bedroom is the furthest from the boiler. The whole heating system is not very old (~12 years). It has only been so loud for the last 2 nights, and I noticed it gets louder with the dropping temperature at night (for example, in the first night, when this started, there were -2°C at night). We've tried bleeding the radiators on both ends of our flat and "padding" some of the possibly colliding pipes, but it didn't cut the noise at all.

Do you have any suggestions on what we could do? It's getting really annoying and prevents me from sleeping / wakes me up at night.
