Ok, I started noticing this a couple weeks after getting my car...its come and gone, but continues to bug me every once and a while. When taking a mild to hard turn, the seat feels like it shifts. Just a tiny little bit, but there is definetly lateral movement at the base. I saw someone post this on another forum about thier P5 and was wondering if anyone knew of a cause or has experienced the same problem. Thizanks.
