Having now picked the car up from the Dealership I am happy to report that the rattle that had been driving me nuts has now disappeared!
I believe it was tied in with me having window tints done on the fronts by a third party
....by the time I dropped the car off at the garage this morning the passenger door wouldn't even open!!!
That's also fixed, and I have the chrome mirror caps on as well (fitted for free).....but they were unable to resolve the dink on the passenger door in house so Dentmaster are definately going to have to come and look at it. Bang goes another of my (valuable) days off....all in a good cause though. The only trouble with them fixing that rattle is I'm now noticing a rattle from the rear split seats,
but it's probably that they aren't fully engaged in the seat releases. I'll save that one for Sunday when I can see what I'm doing....and I can also fit my new uprated headlamp bulbs from mikeythemini.....oh, the deep deep joy of it all!!!
