It means that you have a coolant leak. Do you see clouds of white "smoke" (water vapour) from the exhaust after first starting the engine?

The leak results from flattened 'O' rings caused by movement because the straight pipe plastic clips have not been set correctly.

I'm afraid that's an incorrect assumption. It takes a lot of abuse to cause a KV6 MLS gasket to fail.
You say that the garage renewed the fuel filter. Did they fit a complete new assembly? Does it have a clip fitted?
Has the garage performed any tests to verify the claimed overpressurised cooling system and cylinder misfiring? Is there any mixing of oil and coolant?
