I am waiting to hear the outcome of your problem. When I said try it 20 times I meant within a reasonable time frame. Also, I have never heard of air getting in the hydraulic system. I am not saying it can't happen but I have been a member of "the other" board for a while and haven't seen this mentioned there either. I agree on the fact that I would find out what dealership worked on it and call them and ask for a copy of the invoice.
