What were the TRUE circumstances though? Were you sitting in high water and started the car? It would be almost impossible to hydro lock without being in an awfully big body of water. I used to run a front mount CAI in my GTI and lived in Portland ORegon, we get more rain than Boston and I never heard of Hydro lock till I started driving Hondas/Mazdas 5 years ago. We get plenty of rain here in Michigan. I bought the hydro shield and am just careful as one can be. Do you know how much water you got into your motor? Also, your insurance should cover Hydrolock if the dealership doesnt. How did you get the dealership to cover it in the first place?
