i posted about this before and i've now sorted this?

i was told when i last had a service that some bolts "along" one side were missing.
i went into vw and asked what fixings are there.. 3 are hex bolts and 3 are star washers.. months ago i bought a whole set as it came to about 2 quid for the lot.. but due to cold weather i put it off..
i thought the bolts and washers went together...
after looking over the weekend i now know that the engine bash plate thingy that goes under the engine is held in 6 places.
the 3 bolts go along the back end.. the 3 star washers push onto 'threaded spikes' at the front.
what has happened is.. the 3 hex bolts were replaced another? time my car was worked on.. but the 3 star washers were just left off... (probably busted when removed) and the mechanic didnt do sh!t about it...
so jacking the car up a little and putting the three star washers onto these threaded spikes has sorted rattle.
