Been round and round with circles with this. I can't work out what the tinkling/whistling noise is in the below video. It happens under load and is loudest between 3-4K and 5-7K RPM - it get's louder as the car gets warmer.
I have replaced the knock sensor, spark plugs (correct ones used), it's got 98 RON fuel in, the HT leads and coil pack have also been replaced.
I have just sealed up my down-pipe to cat and cat to mid-section with high-temperature silicone and can't for the life of me find anything that is loose under the car.
Any help would be a hugely appreciated.
