I had my timing belt replaced at Heubueger Motors last week. I occasionally notice a grinding sound when I start the engine. It sounds like if you kept cranking the engine after it has turned over. It seems to only happen when it is cold out but since this is a new issue, I cannot confirm this fact.
They replaced the timing belt, adjuster assy, and 2 idler cp belts. The dealer is 40 minutes one way.
I uploaded a youtube video with the sound. It is at the very end. I will try to get a better one probably tomorrow morning when it is cold outside.

Any help is greatly appreciated.
