I recently noticed a few knocks on start up . Knowing i needed a new flywheel & engine mount i had them changed but the knock is still there . Drives / steers fine just on initial start up i get a few clunks then goes . VW had my van recently for a timing belt / water pump & DSG service & they come back with an advisory of “front top mounts noisy” I’m wondering if it could be this ? Cheers
