So now we also have a problem with our nasty: Statement of my wife who is on cure: The car once banged on the AB and dan started the clacking in the engine room… So: I listened to it today because I visited her…. it’s really a speed dependent loud clacking that comes from the valves…. ????? What my people ???? And what might have banged…. Oil is in it… However, it all doesn’t look so oily when I remove the plug from the top u nd inlook (where you fill in oil) RiX
